+
+	* exp_inter.c: https://sourceforge.net/p/expect/patches/22/
+	Fix interact bug - handle reads of 0 length on
+	non-blocking channels by explicitly checking if the channel
+	is non-blocking. Fix by Jack Bates.
+
+	* expect.c: https://sourceforge.net/p/expect/patches/21/
+	Fix eof bug introduced with previous bug fix - ensure that data
+	received just before an eof is processed. Fix by Sergei Golovan.
+
+2014-05-01  Andreas Kupries <andreask@activestate.com>
+
+	* exp_main_sub.c: Updated EXP_VERSION to 5.45.3
+	* configure, configure.in: Updated expect to version 5.45.3
+
+	* expect.man http://sourceforge.net/p/expect/bugs/86/. Report
+	  and fix by Vitezlav Crhonek.
+
+	* expect.c http://sourceforge.net/p/expect/bugs/76/. Report and
+	  fix by Mutsuhito Iikura. On finding a full buffer during
+	  matching the sliding window mechanism slides too far, truncating
+	  the whole buffer and preventing matches across the boundary. Fix
+	  is shortening the slide distance (slide only one 1/3).
+
+	* expect.c: http://sourceforge.net/p/expect/patches/18/. Report
+	  and fix both by Nils Carlson <nils.carlson@ludd.ltu.se>.
+	  Replaced a cc==0 check with proper Tcl_Eof() check.

+
+	* tclconfig/tcl.m4: http://sourceforge.net/p/expect/patches/17/
+	* configure: Extended Tcl header detection for OS X Mountain Lion.
+
+	* exp_main_sub.c: Updated EXP_VERSION to 5.45.2
+	* configure, configure.in: Updated expect to version 5.45.2
+
+	* expect.c: http://sourceforge.net/p/expect/patches/16/. Report
+	  and fix both by Per Cederqvist. Replaced a memcpy with memmove
+	  as the latter properly handles overlapping memory, whereas the
+	  original code does not.
+
+2012-08-15  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_main_sub.c: Updated EXP_VERSION to 5.45.1
+	* configure, configure.in: Updated expect to version 5.45.1
+
+	* exp_chan.c: Applied patch sent in by Ogawa Hirofumi
+	  <hirofumi@mail.parknet.co.jp>. The patch fixes a problem when
+	  talking a tty where the writer has died. Some operating systems
+	  report the condition as EIO with nothing read, while this
+	  actually an EOF. Without the patch the returned data is
+	  incomplete due to the error reported immediately and dropping
+	  data in buffers.

+2012-05-16  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_chan.c: Bug 3526461: Applied patch by Michael Cleverly

+	code which prevents the package from registering with Tcl

+	* exp_inter.c: Hack access to TCL_REG_BOSONLY when not present,
+	became private with Tcl 8.5 and higher.
+	* expect.h: Remove the local fiddling with the memory allocation
+	and panic macros.
+
+	* Dbg.c: Bug 2972727: Applied the parts of Larry Virden's patch
+	  which were still current. Most of it applied to the partially
+	  ansified sources we had in trunk for a time and where errors in
+	  that set of changes, thus out of date now.
+
+	* example/unbuffer: Bug 2949748: Applied patch by Vitezslav
+	  Crhonek <vcrhonek@users.sourceforge.net> to prevent unbuffer
+	  from eating the exit code of the command it ran (regular mode
+	  only, not -p). Slightly modified, I removed the superfluous
+	  'eval' used to invoke 'wait', invoking it directly.
+
+2010-08-27  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* retoglob.c: Fail if the generated glob contains more than
+	two asterisks.  Fixes Expect SF Bug 3010684 (cederqvist)
+
+	* exp_main_sub.c: add return to silence compiler warning.
+	Updated EXP_VERSION to 5.45.0
+
+	* config.guess, config.sub, expect.m4 (removed):
+	* configure, configure.in, tclconfig/tcl.m4: Update to TEA 3.9

+
+	* Dbg.c: account for removal of tcldbgcf.h
+	* DbgMkfl.in, Dbgconfig.in, Dbgconfigure, DbgpkgInd.in (removed):
+	* tcldbgcf.h.in (removed): removed Dbg debugger subcomponent as it
+	no longer built and debugger functionality is included in expect
+	library and binary
+
+	* pty_termios.c: add HAVE_STRING_H include string.h
+	* exp_trap.c: add HAVE_STRING_H include string.h
+
+	* expectk.man, exp_main_tk.c (removed): expectk no longer
+	built. Use tclsh with package require Tk and Expect instead.
+
+	* tests/all.tcl: add package require Expect
+
+	* example/archie, example/autoexpect: minor code cleanup
+	* example/tkpasswd, example/tknewsbiff, example/tkterm: use
+	package require statements in lieu of expectk
+
+2009-11-03  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_command.c (Exp_SpawnObjCmd): Expect SF Bug 2891422. Fixed
+	  error message when the command to spawn could not be executed.
+	  Tried to use a Tcl_Obj* as argument for a %s. Replaced with the
+	  correct char* variable. Thanks to Elchonon Edelson
+	  <eee@users.sourceforge.net> for the report.
+	  Expect SF Bug 2891563 Ditto for the same type of bug when
+	  emitting error 'usage: -ignore unknown signal name'. The
+	  remainder of the exp_error calls are ok however.
+
+	* configure.in: Bumped version to 5.44.1.15.
+	* configure: Regen'd, autoconf 2.59.
+
+2009-07-14  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_clib.c (TclRegComp): Fixed memory leak reported by
+	  <ettlmartin@users.sourceforge.net> in Expect SF Bug 2814263.
+
+2009-06-22  Andreas Kupries  <andreask@activestate.com>
+
+	* pty_unicos.c (pty_stty): Fixed missing double-quotes for sprint
+	  formatting strings. Thanks to <ettlmartin@users.sourceforge.net>
+	  for the report, i.e. Expect SF Bug 2809496.
+
+2009-06-18  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_command.c (Exp_LogFileObjCmd): Fix argument parsing logic
+	  error in the log_file command breaking the use of options -open
+	  and -leaveopen. Applied patch supplied by Andy Belsey
+	  <Andrew.Belsey@Sun.COM>. With thanks for both the analysis of
+	  the problem and the patch.
+
+	* configure.in: Bumped version to 5.44.1.14.
+	* configure: Regen'd, autoconf 2.59.
+
+2009-05-27  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_tty.c (Exp_SttyCmd, Exp_SystemCmd): Applied patch by
+	  Reinhard Max (max@suse.de) fixing buffer-overflows in the 'stty'
+	  command due to an off-by-one error in the buffer size. See the
+	  bugs https://bugzilla.novell.com/show_bug.cgi?id=506873
+	  and  https://bugzilla.novell.com/show_bug.cgi?id=501291
+
+	* configure.in: Bumped version to 5.44.1.13.
+	* configure: Regen'd, autoconf 2.59.
+
+2009-05-06  Andreas Kupries  <andreask@activestate.com>
+
+	* retoglob.c: Accepted the patch by Mike Cumings
+	  <mcumings@users.sourceforge.net> fixing Expect SF Bug 13179.
+	  The updated code checks a (?...) sequence that it contains only
+	  ARE options before processing it as such. This prevents the
+	  misinterpretation of non-capturing paren groups as ARe options
+	  with subsequent segmentation fault.
+
+	* configure.in: Bumped version to 5.44.1.12.
+	* configure: Regen'd, autoconf 2.59.
+
+2008-09-30  Andreas Kupries  <andreask@activestate.com>
+
+	* configure.in: Bumped version to 5.44.1.11.
+	* configure: Regen'd, autoconf 2.59.
+
+	* exp_command.c (Exp_OverlayObjCmd): Fixed Expect SF Bug 2127456
+	  reported by <eee@users.sourceforge.net>, with thanks. Changed
+	  retrieval of command from objv0 (== 'overlay' itself), to
+	  objvi containing the actual user command.
+
+	* expect.c (string_case_first, string_first, eval_case_string):
+	  Applied patch supplied by Andy Belsey <Andrew.Belsey@Sun.COM>
+	  fixing the seg.fault in 'expect -exact'. With thanks for both
+	  the analysis of the problem and the patch. See also Expect SF
+	  Bug 2114547.
+
+2008-08-28  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_trap.c (tophalf): Fixed inverted condition setting the
+	  interpreter used for trap handling to NULL, causing a crash when
+	  trying to handle ^C. This fixes SF Bug 1757471 reported by
+	  Matthias Kraft <matzek@users.sourceforge.net>.
+	* configure.in: Bumped version to 5.44.1.10.
+	* configure: Regen'd, autoconf 2.59.
+
+2008-08-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* exp_main_sub.c (exp_interpreter): cleaner handling of commandPtr
+	to prevent crash. (das)
+
+2008-06-03  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_glob.c (Exp_StringCaseMatch2): Fixed bug in the handling of
+	  glob classes, see SF Bug 1873404. The code tried to match the
+	  closing bracket of a class in the input because it was not
+	  properly skipped after the class was matched successfully.
+	  Additional trace output added.
+	* configure.in: Bumped version to 5.44.1.9.
+	* configure: Regen'd, autoconf 2.59.
+
+2008-05-05  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_pty.c: Minimal ansification of function definitions to match
+	  them to their prototypes where promoted types are otherwise
+	  causing a mismatch for some compilers, like AIX in 64bit mode.
+	* configure.in: Bumped version to 5.44.1.8.
+	* configure: Regen'd, autoconf 2.59.
+
+2008-04-03  Andreas Kupries  <andreask@activestate.com>
+
+	* configure.in: Bumped version to 5.44.1.7.
+	* configure: Regen'd, autoconf 2.59.
+
+	* The following set of changes was sent our way by Reinhard Max
+	  <max@tclers.tk>.
+
+	* exp_command.c: Fixed more compiler warnings, and started
+	* exp_command.h: to ansify the code base, beginning with
+	* exp_inter.c: the introduction of proper function prototypes.
+	* exp_main_exp.c:
+	* exp_pty.h:
+	* exp_tty.c:
+	* exp_tty.h:
+	* exp_win.c:
+	* expect.c:
+	* pty_termios.c:
+	* retoglob.c:
+
+2008-04-03  Andreas Kupries   <andreask@activestate.com>
+
+	* configure.in: Bumped version to 5.44.1.6.
+	* configure: Regen'd, autoconf 2.59.
+
+	* The following set of changes was sent our way by Reinhard Max
+	  <max@tclers.tk>.
+
+	* configure.in: Fixed checking of stty on linux, do not restrict
+	  to specific cpu's. Further try with stdin, and stdin redirected
+	  to /dev/tty when determining if stdout is read.
+
+	* testsuite/configure.in: Brought up to TEA 3.5.
+	* testsuite/aclocal.m4: New file, to import the TEA definitions.
+
+	* Dbg.c: Added missed CONST in declaration and definition of
+	  'debugger_trap'.
+
+	* exp_command.c: Fixed pointer aliasing trouble with
+	  'Tcl_DetachPids', and added the missing initialization of the
+	  command string in the 'overlay' command.
+
+	* expect.c: Fixed missing initialization of 'simple_start' element
+	  of 'ecase'.
+
+	* exp_inter.c: Fixed bogus use of 'slen' in 'intMatch'. The
+	  relevant string is Tcl_Unichar, not Utf.
+
+	* Makefile.in: Replaced bogus INSTALL_ROOT with DESTDIR, and added
+	  missing DESTDIR references to the target for the installation of
+	  the manpages.
+
+2008-02-27  Andreas Kupries  <andreask@activestate.com>
+
+	* expect.c: Fixed refcounting error when parsing a single expect
+	* configure.in: argument into a list of patterns and
+	* configure: actions. Updated the version number to 5.44.1.5.
+	* Dbg.c: Added missing 'return TCL_OK' to debugger_trap.
+
+2007-12-13  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* exp_log.c (expStdoutLogU): correct which buf is output.
+
+	* exp_command.c (Exp_SendLogObjCmd): fix '--' handling
+	(Exp_SendObjCmd): fix '--' handling to expect last argument
+
+2007-09-24  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_inter.c: Changed inclusion of tcl.h to tclInt.h to get the
+	* expect.c: definition of TCL_REG_BOSONLY, which was moved to that
+	  header in Tcl 8.5. Ditto for expect.c, for the macro
+	  TclUtfToUniChar (was a function in 8.4). Expect now compiles
+	  again for both Tcl 8.4 and 8.5.
+
+	* configure.in: Bumped version to 5.44.1.4.
+	* configure: Regenerated.
+
+2007-09-19  Andreas Kupries  <andreask@activestate.com>
+
+	* retoglob.c (EMITC): Keep the characters '^' and '$' quoted as
+	  well, we do not wish to invoke their special interpretation by
+	  the Expect glob matcher.
+	* configure.in: Bumped version to 5.44.1.3.
+	* configure: Regenerated.
+
+2007-08-09  Andreas Kupries  <andreask@activestate.com>
+
+	* retoglob.c: We had ExpChopNested and ExpBackslash locally
+	  ansified (prototypes) to avoid a compiler error on AIX (type
+	  promotion trouble). This now integrated into the mainline
+	  sources, conditional to AIX.
+
+	* expect.c (Exp_TimestampObjCmd): Fixed argument processing broken
+	  by objc,objv conversion. Tried to use command name as the
+	  argument for -seconds. Also did not detect when one argument to
+	  many was specified.
+
+	* configure.in: Bumped version to 5.44.1.2.
+	* configure: Regenerated.
+
+2007-07-17  Andreas Kupries <andreask@activestate.com>
+
+	* expect.c: Circumvented problems with the C compiler by use of a
+	  temporary variable to hold the unicode pointer of a glob
+	  pattern. The computed pattern length given to
+	  Exp_StringCaseMatch was bogus.
+
+	* exp_glob.c: Added tracing of the glob matcher internals (Can be
+	  enabled by define EXP_INTERNAL_TRACE_GLOB). Fixed bug in a guard
+	  condition in the optimized handling of '*'. The bad condition
+	  caused the code to miss possible matches at the beginning of the
+	  input (first char).
+
+	* tests/expect.test: Added tests which check the glob matcher and
+	  RE gate keeping.
+
+	* configure.in: Bumped to 5.44.1.1 to separate this from the
+	  regular 5.44.1 sources.
+	* configure: Regenerated.
+
+2007-07-12  Andreas Kupries  <andreask@activestate.com>
+
+	* expect.c: Found bugs mismanaging input and pattern in the
+	* exp_glob.c: updated glob matcher. We cannot check for '\0'
+	  anymore to find the end of the string, these are counted
+	  arrays now. Rewritten to use sentinel pointers.
+
+2007-07-11  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_chan.c: Converted the buffering system from UTF-8 in Tcl_Obj
+	* exp_command.h: to UTF-16 C-array, to avoid the repeated conversion
+	* expect.c: of the input from utf-8 to utf-16. Updated the glob
+	* exp_glob.c: matching code to use the same tricks for speed which
+	* exp_inter.c: are used by the Tcl core. Extended the regexp
+	* exp_log.c: matching path with a glob matcher which uses a gate
+	* exp_log.h: keeper glob pattern to weed out most non-candidates
+	* retoglob.c (New file): in a speedy manner. Regexp matching now
+	  has to be done only for the small number of candidates
+	  identified by the gate keeper. Overall speed improvement as glob
+	  matching is faster than regexp matching. Added code translating
+	  regular expressions into their gate keeper glob pattern.
+
+	* Dbg.c: Converted the lot of argc,argv based command
+	* exp_command.c: implementations over to objc,objv.
+	* expect.c:
+	* exp_main_sub.c:
+
+	* Dbg.c: Cleaned up the direct access to interp->result,
+	* exp_command.c: replaced with the proper functions and
+	* expect.c: Tcl_Obj's.
+	* exp_main_exp.c:
+	* exp_main_sub.c:
+	* exp_main_tk.c:
+	* exp_prog.h:
+	* exp_trap.c:
+	* exp_tty.c:
+	* exp_win.c:
+	* exp_win.h:
+
+	* tests/cat.test: Added proper 'package require Expect'
+	* tests/expect.test: to the test setup code (JeffH).
+	* tests/logfile.test:
+	* tests/pid.test:
+	* tests/send.test:
+	* tests/spawn.test:
+	* tests/stty.test:
+
+	* exp_command.c: Reformatted overlong lines, whitespace,
+	* expect.c: comments. Added braces to some if-constructs.
+	* exp_inter.c: Reworked if-constructs interleaved with
+	* exp_tty.c: #if for better formatting in emacs.
+
+	* Dbg.c: Added note about unhandled cases in a switch.
+	* exp_chan.c: Added code to suppress unhandled warning for
+	  unreachable code.
+	* exp_command.c: Removed unused variable.
+	* expect.c: Removed unused static function, added code to suppress
+	  unhandled warning for unreachable code.
+
+	* exp_command.c: Fixed typo in comment.
+
+2007-06-28  Andreas Kupries <andreask@activestate.com>
+
+	* Merged changes from the official version 5.44.1 of expect into
+	  the SF sources. See the details below.
+
+	  --------------------
+	  Marius Schamsula <marius173@mchsi.xcom> reported tclconfig
+	  missing, evidentally for new TEA.
+
+	  Lots of massaging to fix TEAification of Makefile and configure
+	  including that version numbers will now be full three part.
+
+	  Daniel Wong <danielwong@berkeley.xedu> noted the home page
+	  should note that Wikipedia has a very readable entry for Expect.
+
+	  Andre Alves <aalves@escloyalty.xcom> noted passmass needed some
+	  fixes to handle Solaris 9 passwd prompt changes.
+
+	  Andreas fixed several things: changes to better support TEA, fix
+	  debugger interaction with nonblocking mode, and probably other
+	  things I'm overlooking.
+
+	  Martin Dietze <di@fh-wedel.xde> noted that autoconf 2.59 is
+	  confused by C comment after undefs in expect_cf.h.in.
+
+	  Added additional code to unbuffer -p so that if a process
+	  earlier in the pipeline exits, unbuffer attempts to recover any
+	  remaining output from the spawned proc before unbuffer itself
+	  exits.
+
+	  Jeffrey Hobbs noted that once stty was called, a bg'd script
+	  would be suspended at exit.  Turned out to be overaggressive
+	  code in stty that recorded what 'damage' the user might have
+	  caused when calling stty in the first place.
+
+	  Jens Petersen provided patch to make setpgrp configure better on
+	  some Linux systems.
+
+	  Added example/getpassck script to test for getpass bug.
+
+	  multixterm had debugging stuff leftover ("hello").
+	  --------------------
+
+2006-02-27  Andreas Kupries <andreask@activestate.com>
+
+	* exp_main_sub.c: Added command 'exp_configure' for magic configuration.
+	* exp_command.c:  Accepts option -strictwrite. Default is 0, ignoring
+	* exp_chan.c:     write errors (compatible to 5.41). Setting to 1 re-
+	* expect_tcl.h:   activates 5.42 behaviour.
+
+2006-01-25  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tclconfig/tcl.m4, configure: Fix LD_SEARCH_FLAGS setting in tcl.m4
+
+	* example/unbuffer: whitespace police
+
+	* example/beer.exp: brace exprs
+
+	* expect.man: use clock instead of exec date, minor nroff fixes.
+
+2006-01-24  Andreas Kupries <andreask@activestate.com>
+
+	* tclconfig/tcl.m4: Updated to TEA 3.5
+	* configure.in:     Ditto.
+	* configure:        Regenerated.
+
+2006-01-10  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tests/expect.test: ensure iso8859-1 for /tmp/null (steffen).
+
+2005-09-19  Andreas Kupries <andreask@activestate.com>
+
+	* exp_chan.c (ExpOutputProc): Added guard to intercept and ignore
+	  empty write operations, i.e. operations trying to write zero
+	  bytes.
+
+2005-09-09  Andreas Kupries <andreask@activestate.com>
+
+	* exp_chan.c (ExpBlockModeProc): No, stdin is not ok (See last
+	  entry). Fixed.
+
+2005-07-07  Andreas Kupries <andreask@activestate.com>
+
+	* exp_chan.c (ExpBlockModeProc): Expect SF Bug 1108551. Excluded
+	  manipulation of the blocking status for stdin/stderr. This is
+	  handled by the Tcl core itself and we must absolutely not pull
+	  the rug out from under it. The standard setting to non-blocking
+	  will mess with the core which had them set to blocking, and
+	  makes all its decisions based on that assumption. Setting to
+	  non-blocking can cause hangs and crashes. Stdin is ok however,
+	  apparently.
+
+	  This problem was introduced at '2004-06-14'.
+
+2005-06-22  Andreas Kupries <andreask@activestate.com>
+
+	* exp_chan.c:    Fixed bug causing crash of expect on exit when a
+	* exp_command.c: Tcl channel is used with -(leave)open more than
+	* exp_command.h: once. It tried to close such channels multiple
+	  times, going through already freed memory. Added data structures
+	  to track and refcount all such channels, to close them only when
+	  the last user goes away.
+
+2005-06-09  Andreas Kupries <andreask@activestate.com>
+
+	* Makefile.in:  Upgraded build system to TEA 3.2.
+	* configure.in:
+	* config.guess:
+	* config.sub
+	* exp_main_sub.c:
+	* aclocal.m4:
+
+2005-03-29  Andreas Kupries <andreask@activestate.com>
+
+	* exp_chan.c: Fixed problem with debugger introduced at '2004-06-14'.
+	* tcldbg.h:   For a nonblocking stdin the debugger blowed up on the
+	* Dbg.c:      empty reads it could get, exiting the application. I
+	              guess that this was an implicit 'panic'. Fix:
+
+		      - Split ExpBlockmodeProc into high- and lowlevel
+		        code, the latter for use by the debugger. The
+		        high-level code tells the debugger which state
+		        stdin is in (doing this explicitly because if
+		        FIONBIO is used it is not possible to query the fd
+		        directly, and I saw no reason to #ifdef for fcntl
+		        which can).
+
+		      - Debugger now exports a function for use by the
+		        blockmode proc, and in each interaction it checks
+		        for nonblocking input, forces blocking if
+		        necessary. At the end of each interaction the true
+		        mode is restored. Both operations use the
+		        low-level blockmode code.
+
+2005-03-07  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* exp_tty.c (Exp_SttyCmd): fix from Libes that controlling
+	terminal check example (book p372) by restricting set of
+	exp_ioctled_devtty variable.
+
+2005-02-15  Andreas Kupries <andreask@activestate.com>
+
+	* Merged changes from the official versions 5.42.1 and 5.43.0 of
+	  expect into the SF sources. See the details below.
+
+	  --------------------
+	  Martin Forssen <maf@tkrat.xorg> fixed bug in ExpOutputProc
+	  that caused misbehavior during partial writes.
+
+	  Someone noted that gets stdin behaves differently (returns -1
+	  immediately) from tclsh because with 5.42, stdin is unblocked by
+	  defaults.
+
+	  Robroy Gregg <robroy@armory.xcom> noted that expect_background
+	  ignores timeouts.  Added to documentation.
+
+	  Jens Peterson <peterson@redhat.xcom> provided patch for
+	  "mkpasswd -vo".
+
+	  Gary Bliesener <gary.bliesener@nextel.xcom> noted that
+	  multixterm failed on his system which had an old Tk that didn't
+	  support the Tk package.
+
+	  Removed beta designation.
+
+	  Daniel A. Steffen <steffen@ics.mq.edu.xau> provided patch for
+	  MacOS to avoid panic-redefinition.
+	  --------------------
+
+2005-01-21  Andreas Kupries <andreask@activestate.com>
+
+	* exp_inter.c: Changed all uses of 'time(3)' to Tcl_GetTime. IOW
+	* expect.c:    go through the abstract core API instead of
+	               directly acessing OS time. This makes the code
+	               dependent on Tcl 8.4, as Tcl_GetTime was not public
+	               before. See TIP #73 for its introduction into the
+	               public API. As for the reason behind _this_ change
+	               see TIP #233. Our change here now causes Expect to
+	               be automatically in sync with any virtualization
+	               set up in the core.
+
+2004-08-19  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_chan.c (ExpOutputProc): Added code posted by Don on
+	  c.l.t. to handle interrupted system calls (EAGAIN).
+
+2004-07-15  Andreas Kupries  <andreask@activestate.com>
+
+	* Merged changes from the official version 5.42b0 of expect into
+	  the SF sources. See details below.
+
+	  --------------------
+	  Alexander Doktorovich <alexander.doktorovich@ericsson.xcom>
+	  wanted to use Expect as a filter.  This is possible but 'too
+	  hard'.  To make it easier, added close_on_eof command to control
+	  whether expect/interact automatically close the channel on eof.
+	  This should simplify/enable other scripts.
+
+	  Kurt Heberlein <kurth@3pardata.xcom> noted that Expect would
+	  hang. Andreas tracked it down to a change in Tcl such that when
+	  Tcl had data left in its buffers, it would check for more data
+	  rather than returning what it had to Expect first.  If no data
+	  was forthcoming then Tcl would hang because the pty driver runs
+	  in blocked mode.  Recoded to use nonblocking mode.
+
+	  Yi Luo <yluo@brocade.xcom> noted that multixterm xterms were
+	  reporting the parent's X window ids (via the WINDOWID env
+	  variable) instead of the new ones.
+
+	  Dick Van Deun <dirk@dinf.vub.ac.xbe> noted that kibitz expects
+	  to find write in /bin but it is in /usr/bin on Slackware.  Seems
+	  safe to drop the prefix.
+
+	  Steve Lee <steve@tuxsoft.xcom> noted that building Expect failed
+	  on Linux when built from scratch because stty ends up in
+	  /usr/local/bin rather than the assumed /bin.  Added code to
+	  support this.
+	  --------------------
+
+2004-06-14  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_chan.c: Integrated the block mode proc I got by mail from
+	  Don Libes into the channel driver. This fixes an error with
+	  expect hanging on some input if the situation is just
+	  right^Hwrong. Basically if the buffers in driver, Tcl IO core
+	  and Expect itself are aligned just so it can cause Expect to
+	  block in all call to the OS for more data even if all the data
+	  it needs is in ts buffers. Because the driver is blocking and
+	  the Tcl core was told that it can run in non-blocking mode. with
+	  the block mode proc in place the driver knows that it should be
+	  non-blocking and is able to tell this to the OS as well. The
+	  call to the OS still happens, but is not blocking anymore, and
+	  so the problem is gone.
+
+	  A number of incompat changes in the Tcl IO core to work around
+	  this problem in Expect will be removed now.
+
+2004-06-03  Andreas Kupries  <andreask@activestate.com>
+
+	* aclocal.m4 (TCLHDIRDASHI): Extended with path to unix headers as
+	  well.
+	* expect_tcl.h: Added inclusion of <stdio.h>.
+	  Both changes required for Expect to compile against Tcl 8.5
+	  after the header reform.
+	* configure: Regenerated.
+
+2004-05-19  Andreas Kupries  <andreask@activestate.com>
+
+	* Merged changes from the official version 5.41 of expect into the
+	  SF sources. See details below.
+
+	  --------------------
+	  Simon Taylor <simon@unisolve.com.xau> provided fix for interact
+	  -o which was completely broken by 5.40.1.
+
+	  Added scroll support to official tkterm.  Copied all fixes
+	  from/to term_expect to/from tkterm.
+
+	  Kiran Madabhushi <maskiran@hotmail.xcom> encountered interact
+	  diagnostics incorrectly pointing to expect_background.  Also,
+	  found multiple -o flags behaving unexpectedly.  Added diag.
+
+	  Kristoffer Eriksson <ske@pkmab.xse> noted typo in SIMPLE code in
+	  exp_inter.c.  However, this is extremely unlikely to affect any
+	  machines.
+
+	  Reinhard Max <max@suse.xcom> noted that "make test" failed when
+	  run in the background.  The log testcase was testing the
+	  send_tty command.  Added code in both Expect and in the test to
+	  handle this.
+	  --------------------
+
+2004-02-25  Andreas Kupries  <andreask@activestate.com>
+
+	* Merged changes from the official version 5.40 of expect into the
+	  SF sources. See details below. Partially already done (Rich
+	  Kennedy's patch).
+
+	  --------------------
+	  Eric Raymond <esr@snark.thyrsus.xcom> provided troff-related
+	  fixes for the expect, lib, and dislocate man pages.
+
+	  Rich Kennedy <rickenne@cisco.xcom> noted a bug having to do
+	  with our caching of whether we have registered a filehandler.
+	  This broke when Tcl was setting a handler on the same file.
+
+	  Ken Pizzini <ken.pizzini@explicate.xorg> provided patch for
+	  leak in spawn error handling.
+
+	  Pete Lancashire <plancashire@columbia.xcom> noted autopasswd
+	  example broke on Solaris which capitalized prompts.
+	  --------------------
+
+2003-10-20  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_event.c (exp_get_next_event): Applied a patch made by Don
+	  Libes in response to a bug report posted to news:comp.lang.tcl
+	  by Rich Kennedy <rickenne@cisco.com>. Patch was posted to c.l.t
+	  too.

+2003-09-05  Andreas Kupries  <andreask@activestate.com>
+
+	* Merged changes from the official version 5.39 of expect into the
+	  SF sources. See details below. Partially already done.
+
+	  --------------------
+	  Poorva Gupta <poorva@cup.hp.xcom> noted that grantpt/unlockpt
+	  order was backward.  Strange that this was never a prob before!
+
+	  Eric Raymond <esr@snark.thyrsus.xcom> provided a troff-related
+	  fix for the multixterm man page.
+
+	  Nicolas Roeser <n-roeser@gmx.xnet> noted confusion with md5 so I
+	  made the Expect page more explicit about which file that hash
+	  was based on.
+
+	  Josh Purinton noted that earlier fix wasn't quite right.  Exit
+	  on INT/TERM should cause Expect to exit with signal embedded in
+	  status.  He also requested I obfuscate email addresses in this
+	  file.
+
+	  Guido Ostkamp <Guido.Ostkamp@t-online.xde> and Igor Sobrado
+	  <sobrado@string1.ciencias.uniovi.xes> noted that fixline1
+	  rewrote scripts to be expect scripts even if they were expectk
+	  scripts.
+
+	  Dirk Petera <dirkpetera@yahoo.xcom> noted that any_spawn_id used
+	  to work but did no longer.  Looks like a bug left over from the
+	  the I18L conversion.  Fixed.
+
+	  Steve Szabo noted exp_log_file -open channel failed.  Fixed.
+
+	  Fixed bug from 5.31 that prevent stty from returning messages
+	  from underlying program.
+
+	  Thomas Dickey <dickey@herndon4.his.xcom> noted that ncurses
+	  ignores 2-char term names because of, well, poor assumptions and
+	  coding.  Changed tkterm to use longer names.
+
+	  Heath Moore <hmoore@systran.xcom> noted that exp_clib could lock
+	  up if remtime happened to be precisely 0.  Recoded to avoid.
+
+	  At request of Per Otterholm <otterholm@telia.xcom>, wrote script
+	  to read from stdin and echo passwords (exercise 9 in Tk chapter
+	  of Expect book).  Added to example directory as passwdprompt.
+
+	  Josh Purinton <josh@purinton.xorg> pointed out that by default,
+	  SIGINT/TERM should cause expect's return status to be 1, not 0.
+
+	  Paul Reithmuller <paul.reithmuller@eng.sun.xcom> noted that
+	  unbuffer shouldn't postprocess its output.  Added stty_init.
+
+	  Mordechai T. Abzug <morty@sanctuary.arbutus.md.xus> noted that
+	  log_file wasn't recording -append status.
+
+	  James Kelly <macubergeek@comcast.xnet> noted weather example
+	  needed new source.
+
+	  Dimitar Haralanov <mitko@tahoenetworks.xcom> noted that interact
+	  dumped core with interact { timeout 1 }

+
+2003-02-17  Andreas Kupries  <andreask@activestate.com>
+
+	* Makefile.in:
+	* configure.in: Removed the check of configure against
+	  configure.in and Makefile.in. It is a hassle to deal with when
+	  trying to build straight from CVS, making unsupervised automatic
+	  builds difficult
+
+2003-02-14  Andreas Kupries  <andreask@activestate.com>
+
+	* configure.in:   Made expect aware of tcl stubs. Derived from the
+	* exp_command.h:  patches to expect done by Steve Landers
+	* exp_command.c:  <stevel@digital-smarties.com>. Modifications:
+	* exp_main_sub.c  No global cmdinfo structures for 'close' and
+	* exp_main_exp.c: 'return'. Made this per-interpreter information
+	* exp_main_tk.c:  as it should be. Using interp assoc data for this.
+
+	NOTE: stubs is not default, but has to be activated via '--enable-stubs'.
+
+	* configure:      Regenerated.
+
+2003-02-14  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_chan.c (exp_close_all): Save the nextPtr in a local variable
+	  before calling 'exp_close' as 'expStateFree' can be called from
+	  it under some circumstances, possibly causing the memory
+	  allocator to smash the value in 'esPtr'.
+
+2003-02-03  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_log.c (expLogChannelOpen): Fixed the bug reported on
+	  comp.lang.tcl by Mordechai T. Abzug
+	  <morty@sanctuary.arbutus.md.us>. The bugfix itself was provided
+	  by Don Libes.
+
+2002-10-09  Andreas Kupries  <andreask@activestate.com>
+
+	* exp_command.c (Exp_SpawnCmd): Tcl_GetChannelHandle expected a
+	  ClientData*, but got an int*. sizeof(int) != sizeof(ClientData)
+	  on 64bit platforms. Crashed the command on a PA-RISC 2.0 machine
+	  with --enable-64bit set. Fix: Use temp. variables of type
+	  ClientData to retrieve the fd's, and copy this into the actual
+	  variables, with a cast to int.
+
+2002-09-25  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* configure: regen'ed
+	* configure.in: use tcl_libdir in EXP_LIB_SPEC instead of
+	${INSTALL_ROOT}${exec_prefix}/lib (steffen)
+
+	* exp_main_tk.c (Tk_Init2): don't call XSynchronize on OS X.
+
+2002-08-08  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* Merged changes from the official version 5.38 of expect into the
+	  SF sources. See details below.
+
+	* Makefile.in: Added generation of MD5 checksum for distributed
+	  archive.
+	* rftp:         Bugfix by Curt Schroeder, see HISTORY
+	* HISTORY:      Updated with new info.
+	* configure:    Updated version info.
+	* configure.in: Updated version info.
+
+2002-06-26  David Gravereaux <davygrvy@pobox.com>
+
+	* example/weather: Updated script to use rainmaker.wunderground.com
+	instead of cirrus.sprl.umich.edu.  The old service is closed.
+	Added Larry Virden's notes about how rainmaker needs reverse DNS
+	from the peer making the connection or no data can retrieved.
+	This appears to be a blind error condition.
+
+2002-06-17  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* exp_main_tk.c: #ifdef'd definition of "matherr". This hack is
+	  not required for 8.4 anymore. But still for 8.3.
+
+2002-03-25  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* exp_main_sub.c: Fixed typo in merge of #459646. Thanks to Hemang Lavana.
+
+ 	* exp_log.c (expStdoutLogU): Merged fix for SF Bug #513382 into
+	  the HEAD (The source of the patch is "expect-sf418892-sf439042-branch").
+
+	  Use Tcl_WriteChars/Tcl_Flush instead of 'fwrite' for tcl 8.1 and
+	  beyond to enforce correct conversion of the internal UTF/8 into
+	  the external representation.
+
+	* Merged fix for SF Bug #459646 into the HEAD (The source of the
+	  patch is "expect-sf418892-sf439042-branch").
+
+	* Merged fix for SF Bug #439042 into the HEAD (The source of the
+	  patch is "expect-sf418892-sf439042-branch").
+
+	* Merged fix for SF Bug #418892 into the HEAD (The source of the
+	  patch is "expect-sf418892-sf439042-branch").
+
+2002-03-23  Don Libes  <libes@users.sourceforge.net>
+
+	* Andreas Kupries mods to provide CONST support per TIP 27 (Fixed
+	  SF Patch #525074).
+
+2002-02-25  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* expect.c: Applied patch by Don Libes fixing improper
+	  internationalization.
+
+2002-02-21  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* expect.man: Changed the paragraph about exp_continue to
+	  contain information about the flag "-continue_timer". This fixes
+	  the bug SF #520630.
+
+2002-02-08  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* expect.man: Changed abbreviation of "-notransfer" from "-n" to
+	  "-not". "-n" is no longer unique due to the addition of
+	  "-nocase". This fixes the bug SF #514994.
+
+2002-02-07  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* Applied patch for SF #514590 to correct behaviour of expect when
+	  expecting and send from and to bogus spawn id's.
+
+2002-01-16  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* Resynchronization of SourceForge with Don's sources to Expect
+	  version 5.34. The changes are
+
+	  Don Porter <don.porter@nist.gov> provided package-related fixes
+	  for test suite.
+
+	  Brian Theado <brian.theado@usa.net> noted that interact's -re
+	  support broke when offsets kicked in.  Turned out that the
+	  regexp engine supports them during execution but the results are
+	  delivered RELATIVE to the offset.  (I suspect this was done
+	  due to expediency.)
+
+2001-12-05  Andreas Kupries  <andreas_kupries@users.sourceforge.net>
+
+	* exp_inter.c: Applied patch posted by Don libes to c.l.t. on his
+	  behalf to keep the SF repository in sync with his changes. Don's
+	  notes: I obviously missed the fact that although
+	  "Tcl_RegExpExecObj" supports offsets, they aren't delivered to
+	  "Tcl_RegExpGetInfo".
+
+2001-09-12  David Gravereaux <davygrvy@pobox.com>
+
+	* 'telco-tec-win32-branch' branch created.
+
+2001-08-01  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* Dbg.c (Dbg_On): fixed handling of stepping. Bug: #446412
+
+2000-04-26  Rob Savoye  <rob@welcomehome.org>
+
+	* pty_termios.h: Only include stropts.h if it exists, rather than
+	deciding it exists based on HAVE_PTMX.
+	* configure.in: Make sure libpt exists, rather than blindly using
+	it for all our configure tests, which then all fail. Also assume
+	our svr4 style ptys are broken, if /dev/ptmx exists, but stropts.h
+	doesn't exist.
+
+1999-08-31  Jennifer Hom  <jenn@scriptics.com>

+	* expect.c: Fixed bug in token parsing where index was not being
+	incremented properly.
+
+	* configure.in: Changed version number to 5.31.
+
+	* aclocal.m4: Fixed CY_AC_LOAD_TKCONFIG so it tests for Tk_Init

+	added TCL_BUILD_LIB_SPEC to the set of flags used in this test to
+	avoid linker errors.
+
+	* Dbgconfig.in: move CY_*_TCLCONFIG tests below AC_PROG_CC so it
+	will work with gcc
+
+Thu Mar 20 14:27:45 1997  Geoffrey Noer  <noer@cygnus.com>
+

+
+        * configure.in, configure: For a solaris2 machine doing a static

+
+Wed Nov 22 08:49:01 1995  Rob Savoye  <rob@chinadollchinadoll.cygnus.com>
+
+	* Most files: Update to expect 5.18.1.
+
+Fri Nov 17 17:31:55 1995  Rob Savoye  <rob@chinadoll.cygnus.com>
+
+	* configure.in: Add support for SCO OpenServer. It doesn't like
+	the trap either.
+
+Thu Nov 16 09:28:53 1995  Rob Savoye  <rob@chinadoll.cygnus.com>
+
+	* configure.in: Use $host to get the OS type rather than trying to
+	get the host name ourselves. Use the $host to set the

+	also now configures in the background.
+	* configure.in, Dbgconfig.in, testsuite/configure.in: Use

+	X11_LDFLAGS, X11_LIBS.  Link X11 statically on Solaris, SunOS and
+	HPUX.
+
+Thu Oct 19 20:55:54 1995  Fred Fish  <fnf@cygnus.com>
+
+	* Makefile.in: Remove extraneous tabs and blanks in otherwise

+
+	* testsuite/aclocal.m4: New file.  Include ../aclocal.m4.

+
+Thu Aug  3 22:47:36 1995  Jeff Law  (law@snake.cs.utah.edu)
+
+	* pty_termios.c (HAVE_PTMX): Undefine if both HAVE_PTYM and
+	HAVE_PTMX are defined (as happens for hpux10).
+
+Thu Jul 27 16:31:23 1995  J.T. Conklin  <jtc@cygnus.com>
+
+	* Makefile.in (configure): Removed rule that automatically
+	rebuilds configure script.  Users might not have autoconf.
+
+Tue Jul 18 23:15:03 1995  Fred Fish  <fnf@fishbowl>
+
+	* expect.c (Exp_ExpectGlobalCmd):  Cast ckrealloc first arg to char*.
+
+Sun Jun 18 13:02:41 1995  Fred Fish  <fnf@amigalib.com>
+
+	* configure, configure.in (XLIBS):  When adding -lX11, also preserve
+	the previous libraries that we went to the trouble of finding.
+
+Sun Jun 18 12:15:44 1995  Fred Fish  <fnf@amigalib.com>
+
+	* Makefile.in (exp_clib.o): Add dependencies.
+
+Mon May  1 16:50:22 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* configure.in: Also set XINCLUDES in the Makefile.
+
+Fri Apr 28 18:56:02 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* aclocal.m4: Create a clone of AC_C_CROSS called CY_C_CROSS that
+	has better error handling in case the native compiler is hosed.
+	* aclocal.m4: Look for tcl and tk directories as just tcl (and tk)
+	or tcl0-9 (and tk0-9) so it doesn't match the tclX
+	release. Print an error and exit if any of the --with-{tcl,tk}*
+	options are used and point to bogus paths. Based Tcl header search
+	on tclInt./h rather than tcl.h.
+	* Makefile.in: Add dependancies for back in for configure and
+	Dbgconfigure targets.
+
+Mon Apr 24 16:46:01 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* exp_command.c, exp_event.h, exp_inter.c, exp_main_tk.c,
+	exp_poll.c, exp_select.c, exp_simple.c, exp_tk.c, exp_trap.c,

+
+Fri Apr 14 12:00:39 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* configure.in: Copy Dbg_cf.h to objdir, not srcdir.
+
+Tue Apr 11 18:52:24 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* aclocal.m4: Split the macros so header and library searches are
+	seperate macros. AC_PATH_{TCL,TK} nows only calls the macros. Lots
+	of optimization to the AC_PATH_T* macros. Supports the use of
+	--with-tclinclude, --with-tcllib, --with-tkinclude, --with-tklib
+	to specify alternative search dirs for tcl and tk stuff.
+	* Makefile.in, testsuite/Makefile.in: Re-write targets for
+	configure, Dbgconfigure so they work in an unconfigured srcdir.
+	* configure.in: Put AC_PATH_X before AC_PATH_TK and make the TK
+	test conditional. Fix how Dbgconfigure gets passed the Tcl header
+	dir to use --with-PACKAGE which is much simpler. Removed the test
+	for user override of X search paths since AC_PATH_X uses.
+	--x-includes and --x-libraries instead.
+	* Dbgconfig.in: Use AC_PATH_TCLH to find just the headers, and
+	test for LynxOS.
+	* debugger/: Remove directory. Recursive configuring is so much
+	easier...
+	* DbgMkfl.in, Dbg_cf.h.in, Dbg.c, Dbg.h, Dbgconfigure,
+	Dbgconfig.in: Sigh, moved back to the top-level expect directory.
+
+Wed Apr  5 17:25:45 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* configure.in: Add a trap so the configure runs in the
+	background.
+
+Thu Mar 16 16:56:08 1995  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* debugger: New directory for the Tcl debugger.
+	* debugger/Dbg.c, debugger/Dbg.h, debugger/Dbg_cf.h.in: Moved from
+	the top level expect directory so it builds standalone.
+	* DbgMkfl.in, debugger/Makefile.in: Moved to debugger dir and
+	renamed.
+	* install-sh, mkinstalldirs: New files borrowed from the autoconf
+	distribution.
+	* aclocal.m4: New autoconf macros.
+	* Makefile.in: Tweaked so it's recursive.
+	* configure.in: Use new macros in aclocal.m4 rather than hunting
+	for the Tcl and Tk stuff ourseleves.
+	* debugger/Makefile.in: Build debugger standalone.
+	* testsuite/Makefile.in, testsuite/configure.in: New files for
+	autoconf support.
+	* exp_test.c, testsuite/exp_test.c: Move test file.
+
+Fri Jan 13 15:30:30 1995  Ian Lance Taylor  <ian@sanguine.cygnus.com>

+
+Thu Oct 20 18:04:06 1994  Rob Savoye  <rob@darkstar.cygnus.com>
+
+	* Makefile.in: Add X11_INCLUDE_FLAGS so top level flags get used
+	too.
+
+Tue Jun 14 12:32:07 1994  David J. Mackenzie  (djm@rtl.cygnus.com)
+
+	* aclocal.m4: Copy from TCL directory.
+	* configure.in: Improve checks for installed Tcl and Tk.
+	* configure: Rebuilt.
+
+Tue Jun  7 13:52:34 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

+Wed May 18 12:21:06 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

+
+Fri Apr 29 16:49:36 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
+
+	* Makefile.in (install): Always use else in if conditional to
+	avoid Ultrix sh bug.
+

+	bounds. (ok since it doesn't get used).
+
+Mon May 17 19:51:52 1993  Rob Savoye  (rob@cygnus.com)
+
+	* configure.in: Change test for ranlib so it kicks out "true"
+	rather than "@:" if it can't be found.
+
+Thu Apr 15 14:11:50 1993  Rob Savoye  (rob@cygnus.com)
+
+	* configure.in, Makefile.in: If using ptmx's (SVR4 style pty's)
+	then check for libpt.a too.
+
+Thu Apr  8 17:13:39 1993  david d `zoo' zuhn  (zoo at cirdan.cygnus.com)
+
+	* Makefile.in: all doesn't depend on $(SCRIPTS).  When building
+	$(SCRIPTS) using fixline & sources in $(srcdir), not the current
+	directory.  When installing manpages, install from $(srcdir).
+	Don't install like "install foo $(bindir)" but rather "install foo

+
+Thu Oct 22 17:35:07 1992  Rob Savoye  (rob@cygnus.com)
+
+	* command.c: Added a "send_log" command. It only writes to a log
+	file if one was opened by the "log_file" command.
+
+	* main.c: Added setbuf commands for stdin, stdout, stderr to turn
+	off buffering.

+Expect FAQ (Frequently Asked Questions)
+
+An HTML version of this FAQ can be found in http://expect.nist.gov/FAQ.html
+
+This FAQ lists common questions, usually about subjects that didn't
+fit well in the book for one reason or another (or weren't
+indexed sufficiently well so that people can't find the answers easily
+enough).  In some cases, I've left the original questions.  I suppose
+I could've stripped off the headers, but it seems more realistic to
+see actual people who've asked the questions.  Thanks to everyone who
+asked.
+
+The man page and the papers listed in the README file should
+also be consulted for highly technical or philosophical discussion of
+the implementation, design, and practical application of Expect.

+
+Expect is a tool primarily for automating interactive applications
+such as telnet, ftp, passwd, fsck, rlogin, tip, etc.  Expect really
+makes this stuff trivial.  Expect is also useful for testing these
+same applications.  Expect is described in many books, articles,

+O'Reilly.

+To: libes@cme.nist.gov
+Subject: Re: pronunciation?
+Date: Tue, 29 May 90 21:26:10 PDT
+
+Those of us in the family pronounce it "OH-stir-howt", where the
+first syllable rhymes with "low", the second with "purr", and the
+third with "doubt".  Unfortunately this isn't the correct Dutch
+pronounciation for a name spelled this way (someplace along
+the line it got misspelled:  it was originally "Oosterhout"), nor
+is it what you'd guess if you use common sense.  So, we've gotten
+used to responding to almost anything.
+
+					-John-
+
+I suppose I should say something in kind.  "Libes" is pronounced
+"Lee-bis" with stress on the first syllable.  Like John though, I've
+gotten used to responding to anything close.
+
+By the way, notice the date on this message.  I had only written
+the first cut of Expect four months earlier.  I asked John how to
+pronounce his name because I had already got a paper accepted into
+USENIX and needed to be able to say his name correctly while giving

+
+Ironically, Tcl was written specifically to halt this very problem.
+
+The author recognized that every utility seems to have its own
+idiosyncratic .rc file or programming language.  Tcl was designed as a
+general-purpose language that could be included with any utility, to

+
+Good point.  While I'm not a Perl guru, I've used it quite a bit
+and it's nice for many things.  But I wouldn't have bothered writing
+Expect in the first place if I thought Perl was ideal.  And many Perl
+experts agree - I know a lot of them who call out to Expect scripts
+rather than do this stuff in Perl - it's that much easier with Expect.
+Expect is also much more mature.  It's portable, stable, robust, and
+it's fully documented - with lots of examples and a complete tutorial,
+too.
+
+In response to someone complaining about how difficult it was to do
+something in Perl, Larry Wall once remarked: "The key to using
+Perl is to focus on its strengths and avoid its weaknesses."  That
+definitely applies here.
+
+Even if you do proceed with Perl, you will find the book
+helpful.  Automating interactive applications has unique pitfalls to
+it and many of the descriptions and solutions in the book transcend
+the choice of language that you use to implement them.

+
+It is my understanding that you are allowed to do just about anything
+with Expect.  You can even sell it.  You need not ask our permission.
+You need not pay for it.  (Your tax dollars, in effect, already have
+paid for it.)
+
+You should not claim that you wrote it (since this would be a lie), nor
+should you attempt to copyright it (this would be fruitless as it is a
+work of the US government and therefore not subject to copyright).
+
+NIST would appreciate any credit you can give for this work.  One line
+may suffice (as far as I'm concerned) although there should be
+something to the effect that this software was produced for research
+purposes.  No warantee, guarantee, or liability is implied.
+
+My management is always interested in feedback on our work.  If you
+would like to send letters of praise describing how Expect has helped
+your business, we would be delighted.  Letters (on letterhead please)
+are strong evidence used by policy makers when deciding where every
+dollar goes.  If you want to send these letters to NIST directly, you
+may send them to the following individuals:

+
+It doesn't matter (much).  What the rules address is whether a gift
+might cause me to make an official decision differently.  This is
+especially a concern because I may very well have to decide whether or
+not to buy products from your company in the future.
+
+There is a clause that says "you may accept gifts from friends,
+regardless of value ... but you should be careful to avoid accepting
+gifts which may create an appearance of impropriety, even if permitted
+as an exception to the gift rules."
+
+I'm still permitted to accept small token gifts, such as a t-shirt
+or reasonably-priced dinner (under $20 per gift to a maximum of $50
+per year from any person or company) - so things are not totally
+ridiculous.  Although the precise values in the gift rules seem rather
+arbitrary, I actually like the gift rules.  They stop a lot of the
+nonsense that used to go on involving gifts.

+
+I know that a lot of other packages have *huge* FAQs but I
+have always believed that this is an indication that their regular
+documentation sucks.  As questions arise that are not addressed well
+by the original docs, the docs themselves should be fixed rather than
+new ones created.
+
+In contrast, I believe that an FAQ should literally be a list of
+frequently asked questions and little else.  An FAQ should not be a
+replacement for good documentation.
+
+In that sense, I have tried to use this FAQ as a second place to
+look rather than a first place.  The place you should always look
+first is Exploring Expect.  At over 600 pages, the book is very
+comprehensive, well-organized, and includes three indices and two
+tables-of-contents to make it very easy to find what you want to know.
+
+The book was not a rush job.  During the three years I spent
+writing it, virtually every question I was asked became incorporated
+as subject material for the book.  I wanted to make sure that the book
+wouldn't need much of an FAQ!
+
+It would not make sense to try and distill the entire book into an
+FAQ (that is actually comprehensive rather that truly frequently asked
+questions).  There's simply too much material there.
+
+So this FAQ is short.  It really tries to stick just to *truly*
+frequently asked questions.
+
+Don
+
+======================================================================
+
+#9. How was this FAQ created?
+
+The Expect FAQ is regularly recreated by a Tcl script which
+produces either text or HTML depending on how it is called.  Using Tcl
+has two nice results:
+   +  I didn't have to choose one format and worry about
+converting it to the other.  (Remember that the FAQ appears in HTML on
+the web and it appears in text in the Expect distribution.)  The more
+common approach - doing conversions in either direction - is really
+painful - plus, it's now easy to generate other formats, too.
+   +  It's much, much easier to keep track of questions and
+answers.  For example, when I add a new question, I don't have to add
+it twice (once at the top and again later with the answer), nor do I
+have to worry about making the links between them.  All this and a lot
+of other stuff is handled automatically - and the source is much more
+readable than the actual HTML.
+(see "FAQbuilder")
+
+You can read about these ideas in a paper that appeared at Tcl '96
+called Writing CGI Scripts in Tcl.  (CGI scripts are the primary focus of the
+paper, but it also spends time on HTML generation for other purposes -
+including the example of highly stylized documents like FAQs.)
+
+I encourage you to examine the source to this FAQ - it
+comes in two parts:
+   +  Expect-specific FAQ source
+   +  Generic FAQ Builder source
+
+The generic FAQ builder has also been used to build several other
+FAQs (unrelated to Expect).

+Perhaps I'm too myopic, but I don't see the need for it.  Most of

+answers to them.
+
+For one reason or another (occasionally a bug fix, but often, just

+Personally, I'd hate being on the other end of something like this.
+Who needs patches every two weeks for problems that are likely not

+
+NIST doesn't distribute software written by other people but if
+you've got relatively small scripts that show off unique ideas and
+techniques that would be educational for the Expect community, I can
+include your script with Expect or put it in a publicly accessible
+directory so other people can get it.  I'm also willing to list links
+in Expect's home page to other web pages about projects that use
+Expect.
+
+There is a Tcl newsgroup, comp.lang.tcl, which many Expect users
+read.  It's pretty good for asking questions about Tcl, and many of
+the readers use Expect so Expect questions are encouraged.  The
+newsgroup is gatewayed to a mailing list (tcl@sprite.berkeley.edu)
+which is further described in the Tcl documentation.

+The overlay command has been in Expect for a long time.  In all that

+
+There is some real humor here.  There seems to be considerable
+debate over what the creature is!  The colophon at the end of the book
+says that it is a chimpanzee.  I like that idea much more than a
+monkey which is what it looks like to me.  My wife, who has a degree
+in zoology, explained to me that chimps are actually the second
+smartest of primates (humans are the smartest).  Chimps are very
+intelligent and can do many things (but not everything) that humans
+do.  Perfect for describing Expect.  Anyway, she says I should be
+honored to have it grace the cover - even in theory.
+
+I remarked to Edie (the cover designer at O'Reilly) that even though
+the cover was nice looking, everyone was going to stare at it and say,
+"Gee, but it looks like a monkey."  She replied "The purpose of the
+cover is just to get people to pick the book up. This cover will do
+that. Don't worry. If you get any rude comments from anyone, at least
+you know they are paying attention."
+
+After being inundated by people pointing out that the animal
+really is a monkey, O'Reilly subsequently decided to acquiesce and has
+changed the colophon to admit that yes it is a rhesus monkey.
+Evidentally, the book from which O'Reilly has been taking those
+pictures from was wrong on this one.

+
+======================================================================
+
+#18. Can Expect understand screen-oriented (Curses) programs?
+
+Yes, it can - with a little clever scripting.  Look at the
+term_expect script for an example.  It uses a Tk text widget to
+support screen-oriented Expect commands.  This technique is described
+very thoroughly in Chapter 19 of Exploring Expect.
+
+Adrian Mariano (adrian@cam.cornell.edu) converted the term_expect
+code (see above) so that it runs without Tk (exercise 4 in Chapter
+19!)  Both term_expect and virterm can be found in the example
+directory that comes with Expect.
+
+An alternative approach to screen-handling was demonstrated by Mark
+Weissman (weissman@gte.com) and Christopher Matheus who modified a
+version of Expect to include a built-in Curses emulator.  It can be
+ftp'd from the Tcl archive as expecTerm1.0beta.tar.Z.  (Note that
+Expecterm does not run with the current version of Expect.)
+
+I like the idea of keeping the curses emulator outside of Expect
+itself.  It leaves the interface entirely defineable by the user.  And
+you can do things such as define your own terminal types if you want.
+For these reasons and several others, I'm not likely to return to
+Expecterm.

+
+#19. Can Expect be run as a CGI script?
+
+Expect scripts work fine as CGI scripts.  A couple pointers might
+help to get you going:
+
+Many Expect scripts can be run directly with one change - the
+following line should be inserted before any other output:
+
+puts "Content-type: text/html\n"
+
+Be sure not to forget that extra newline at the end of the puts.
+
+Next, make sure you invoke external programs using full paths.  For
+example, instead of "spawn telnet", use "spawn /usr/ucb/telnet" (or
+whatever).  Remember that the PATH and other environment variables are
+going to be different than what you are used to.  This is very similar
+to dealing with cron and you can get other good tips and advice from
+reading the Background chapter in the book.
+
+ Another tip: If a script runs fine by hand but not from CGI, just
+log in as "nobody" to the host on which your CGI script runs.  Then
+try running it by hand.  This generally makes it very obvious what's
+going on.  (If you can't log in to the server or can't log in as
+"nobody", use the kibitz trick described in the Background chapter.)
+
+You may find it helpful to use cgi.tcl, a nice collection of
+CGI support utilities for Tcl scripts.  It includes an Expect example
+among many others.  The package includes just about everything:
+tables, frames, cookies, file upload, etc...., with some nice
+debugging support.  It's pure Tcl, no C code - so it's very easy to
+try out and use.

+#20. Can Expect act like a browser and retrieve pages or talk to a CGI script?
+
+From: jasont@netscape.com (Jason Tu)
+Date: Sat, 02 Nov 1996 09:51:03 -0800
+
+I read your book "Exploring Expect" and find Expect is just the tool
+to test Netscape's enterprise server product, since it is very easy to
+use and quick to develop. I figured I would use telnet to send HTTP
+protocol dialog to a HTTP server and simulate how it behaves.  But I
+couldn't get it to work at all.  I am wondering that there might be a
+quick example that you can share with me.
+
+Yes, this is a useful way of testing HTTP servers and running CGI
+scripts (and winning Web contests :-).  You can add error checking and
+other stuff, but here's the minimum your script should have to read a
+web page: 
+
+match_max 100000
+set timeout -1
+spawn telnet $host 80
+expect "Escape character is *\n"
+send "GET $page\r\n"
+expect
+puts "$expect_out(buffer)"
+
+If you want to communicate information to a CGI script, you'll want
+more.  One way to see what needs to be sent is to load a real browser
+with the form and then send it to a fake daemon such as this one:
+
+#!/bin/sh
+/bin/cat -u > /tmp/catlog
+
+Enable this by adding this service to inetd.  Then save the form in
+a temporary file, modify the form's host and port to correspond to
+your own host and whatever port you've chosen to associate with your
+fake daemon.  Now fill out the form and you'll find the form data in
+/tmp/catlog.  Using this, you can determine exactly how to amend your
+Expect script to behave like your browser.

+#21. Can Expect be run from cron?
+
+Expect itself works fine from cron - however, you can cause
+problems if you do things that don't make sense in cron - such as
+assume that there is a terminal type predefined.  There are a number
+of other pitfalls to watch out for.  The list and explanations aren't
+short - which is why there's a whole chapter ("Background") on the
+subject in the book.
+
+Here's one that someone tried to stump me with recently: They told
+me that their program started up and then Expect immediately exited.
+We spent a lot of time tracking this down (Was the spawned program
+really starting up but then hanging - which would indicate a bug in
+the program; or was the program NOT starting up - which would indicate
+a bug in the environment; etc.)  Turned out that Expect wasn't even
+running their program.  They had assumed cron honored the #! line
+(which it doesn't) and so the first line in their script (exec date)
+was being interpreted by the shell and of course, the script did
+nothing after that - because that's what the shell's exec is supposed
+to do!)

+
+ 
+In short, there's no tty when you run a process from inetd.  Echoing

+
+Root-access is needed to open a pty under Unicos.  Thus, all programs
+accessing ptys must be setuid root.  If you do an "ls -l" of programs
+like "script", "xterm", etc, you'll see this.
+
+I have no idea why this is.  The requirement was probably for security
+reasons to begin with, but it has the ironic effect of making more

+
+In fact, there is one known Unicos bug relating to the way uids are

+I've seen this happen because gcc was partially installed.  configure

+You can account for this behavior in your patterns.  Alternatively,

+
+spawn initializes the terminal by using your current parameters and

+The output you are seeing wasn't printed by the send command.
+(I.e., the log_user command is working just fine.)  The output you see

+
+The send command doesn't wait for responses.  The echoing you see

+
+On most systems, Expect does not automatically make a utmp entry.  (A
+utmp entry normally indicates login information which seems kind of
+pointless for Expect scripts.)  This allows Expect to run non-setuid.
+
+Normally, this lack of utmp entries doesn't mean much.  However, a few
+programs actually refuse to run without a utmp entry.  Fortunately,
+there are workarounds:
+
+Program-dependent solutions:
+
+"talk" is the only program I'm aware of that falls into this category.
+One solution is to get ytalk.  ytalk doesn't have this problem plus it
+fixes many other bugs in talk, such as being able to communicate with
+both old and new talk.
+
+Program-independent solutions:
+
+Use a program specifically intended to create utmp entries.  Such
+programs are easy to write or get if you don't have them already.  For
+instance, sessreg is one which comes with the xdm distribution.  And
+Solaris uses utmp_update.  I like this approach because it isolates
+the setuid code in a small single system utility rather than in every
+program on the system that needs this ability.
+
+Tod Olson <tao@stone.lib.uchicago.edu> sent in the following
+example of how to use sessreg.  He says: sessreg works nicely.  Here
+is a fragment showing how we invoke sessreg on our Linux machines.
+Note: sessreg must be able to write utmp.  We decided to make utmp
+work writable, since it's a kinda bogus creature anyhow, rather than
+make sessreg suid root (or whatever).

+Yes, there are some packages that follow this convention, but I don't

+
+I find that I actually write the ^\n pattern very rarely.  And

+
+In fact, the more common line-terminating sequence in Expect is \r\n,

+The problem is that telnet is not recognizing EOF.  (This is quite
+understandable since real users can't actually generate one from the
+telnet user interface.)  The solution is to either 1) explicitly drive
+telnet to kill itself (i.e., a graceful logout) followed by "expect

+
+No, there is no interact-like function in the C library.  The reason
+is three-fold:
+
+1) It is simple enough to write your own.  It's just a loop after
+all:
+
+	while 1 {
+		select/poll()
+		read()
+		write()
+	}
+
+2) There's no way I could possibly provide all the options you might
+need.  In Expect, it's not a problem because the environment is very
+controlled, but in C, it's impossible to control what you might want
+to do.  For example, you mention that you're embedding your code in a
+graphics application.  Graphics packages typically have their own
+event manager, so you wouldn't want a monolithic interact function.
+
+3) The library is intended for embedding in other applications, where
+it rarely makes sense to give the user direct control of a spawned
+process.  That kind of thing makes so much more sense to handle with
+an Expect script than a C program.  The C library was not intended as
+a replacement for Expect.  Expect is really the tool of choice for
+interaction problems, not C.  
+
+In summary, there's very little payoff for the library to supply an
+interact function.  A simple one would only satisfy people who should
+be using Expect anyway - and it's impossible to create one that would
+do everything that everyone wants.  It's easier just to let people
+create their own.

+#46. Can't you make tkterm understand any terminal type?
+
+From: swig@teleport.com (Scott Swigart)
+Newsgroups: comp.lang.tcl
+Date: Tue, 13 Aug 1996 18:50:22 GMT
+
+I looked at tkterm, and it is promising, but it's missing some
+critical features.  For one, I need something that understands various
+terminal types, and can get it's escape sequences from something like
+termcap or terminfo, instead of having them hard coded.  Also, I
+question the ability of an Expect script to keep up if it had 50 or so
+types of escape sequences to parse.  Actual C code would probably have
+to be created to do the parsing, and if you're going to go that far,
+why not just create a terminal widget so you could do something like:
+
+terminal .myterm -type vt220
+
+which is more along the lines of what I was originally looking for.
+
+Yes, that would be divine.  But terminal emulators are horribly
+complex and very little of that complexity can be discerned from the
+termcap file.  For example, compare xterm's human-readable docs (63k
+man page + 18k appendix) to its termcap entry (654 bytes).  Now
+consider the other hundreds of terminals in termcap each with their
+own weird extensions.  I can't imagine what kind of ".myterm configure"
+interface you'd present to the user.  What would you allow the user to
+change?  The nice thing about tkterm is that everything is accessible
+to the user, but I can't imagine doing that through a widget
+interface.
+
+Unfortunately, like everyone else, I don't have the time...
+
+Me neither.  Call me lazy.
+
+As an aside, I wonder why you want the ability for a terminal emulator
+to read termcap/info.  Turns out that it's useless (unless what you
+are doing is testing termcap itself).  Because if your app is using
+termcap in the first place, then it doesn't care what terminal type
+you choose - so why not choose the one that tkterm does?  (And if your
+app isn't using termcap, then you have the converse problem.)
+
+Actually, I and several other people did a fair amount of
+experimentation (i.e., wrote a lot of C code) to do a universal
+terminal emulator - turns out that it's not possible in a general
+sense.  To support any terminal type, you are going to be forced to go
+beyond what termcap/info offers.  I.e., you'll have to handedit the
+definition or add new ones and/or accept certain limitations.
+
+After many revisions, Software - Practice & Experience is
+publishing a paper on tkterm.  The paper includes more insights on the
+difficulties I've mentioned here.  You can get a draft of the paper

+
+I haven't analyzed your script in depth, but this sounds like a
+problem I've seen before - it's due to an implementation deficiency in
+Tcl.  The problem is that when an exec'd process finishes, it raises
+SIGCHLD.  Expect's "wait" sees that it is Tcl's process.
+Unfortunately, there is no way to wait for one of Tcl's processes and
+tell Tcl that you've done so, nor is there any way to have Tcl wait
+itself.  So Expect's wait just returns.  On some systems alas, this
+just causes SIGCHLD to be reraised.
+
+The solution is multipart:
+   1  Tell John he needs to fix this problem.  (I've told him this but he
+didn't agree with me that it's a problem.)  Tcl needs to provide a new
+interface - either to clean up its process or to allow extensions to
+do the wait and pass the status back to Tcl so that it can have it
+later when needed.
+   2  Don't call exec while you are trapping SIGCHLD.  Since this is a
+severe limitation, I recommend you avoid the problem by using
+"expect_before eof" to effectively trap the same event.  If you're not
+already using expect, well, call it every so often anyway.

+
+What's going on is that the spawned process has closed the

+It would be helpful for the expect distribution to contain its version

+Sounds like a misconfiguration problem on your system.  For

+your scripts use 2-character years, you should upgrade to a modern
+version of Tcl.  If your scripts use 4-character years, than you have
+nothing to worry about.

+This is the HISTORY file for Expect.  Modifications made by Cygnus
+support are in ChangeLog. - Don
+
+Date	Version	Description
+-------	-------	------------------------------------------------------
+1/31/06	5.44.1	Marius Schamsula <marius173@mchsi.xcom> reported tclconfig
+		missing, evidentally for new TEA.
+
+1/20/06 5.44.0	Lots of massaging to fix TEAification of Makefile and configure
+		including that version numbers will now be full three part.
+
+		Daniel Wong <danielwong@berkeley.xedu> noted the home page
+		should note that Wikipedia has a very readable entry for
+		Expect.
+
+		Andre Alves <aalves@escloyalty.xcom> noted passmass needed some
+		fixes to handle Solaris 9 passwd prompt changes.
+
+		Andreas fixed several things: changes to better support TEA,
+		fix debugger interaction with nonblocking mode, and probably
+		other things I'm overlooking.
+
+		Martin Dietze <di@fh-wedel.xde> noted that autoconf 2.59 is
+		confused by C comment after undefs in expect_cf.h.in.
+
+		Added additional code to unbuffer -p so that if a process
+		earlier in the pipeline exits, unbuffer attempts to
+		recover any remaining output from the spawned proc before
+		unbuffer itself exits.
+
+		Jeffrey Hobbs noted that once stty was called, a bg'd script
+		would be suspended at exit.  Turned out to be overaggressive
+		code in stty that recorded what 'damage' the user might have
+		caused when calling stty in the first place.
+
+		Jens Petersen provided patch to make setpgrp configure better
+		on some Linux systems.
+
+		Added example/getpassck script to test for getpass bug.
+
+		multixterm had debugging stuff leftover ("hello").
+
+2/7/05	5.43.0	Martin Forssen <maf@tkrat.xorg> fixed bug in ExpOutputProc
+		that caused misbehavior during partial writes.
+
+		Someone noted that gets stdin behaves differently (returns -1
+		immediately) from tclsh because with 5.42, stdin is unblocked
+		by defaults.
+
+		Robroy Gregg <robroy@armory.xcom> noted that expect_background
+		ignores timeouts.  Added to documentation.
+
+		Jens Petersen <peterson@redhat.xcom> provided patch for
+		"mkpasswd -vo".
+
+		Gary Bliesener <gary.bliesener@nextel.xcom> noted that
+		multixterm failed on his system which had an old Tk that didn't
+		support the Tk package.
+
+8/3/04	5.42.1  Removed beta designation.
+
+		Daniel A. Steffen <steffen@ics.mq.edu.xau> provided patch for
+		MacOS to avoid panic-redefinition.
+
+7/6/04	5.42b0	Releasing as beta because nonblocking mode is a big change in
+		the code.  http://expect.nist.gov/beta.tar.gz
+
+		Alexander Doktorovich <alexander.doktorovich@ericsson.xcom>
+		wanted to use Expect as a filter.  This is possible but 'too
+		hard'.  To make it easier, added close_on_eof command to
+		control whether expect/interact automatically close the
+		channel on eof.  This should simplify/enable other scripts.
+
+		Kurt Heberlein <kurth@3pardata.xcom> noted that Expect would
+		hang.  Andreas tracked it down to a change in Tcl such that
+		when Tcl had data left in its buffers, it would check for more
+		data rather than returning what it had to Expect first.  If
+		no data was forthcoming then Tcl would hang because the pty
+		driver runs in blocked mode.  Recoded to use nonblocking mode.
+
+		Yi Luo <yluo@brocade.xcom> noted that multixterm xterms were
+		reporting the parent's X window ids (via the WINDOWID env
+		variable) instead of the new ones.
+
+		Dick Van Deun <dirk@dinf.vub.ac.xbe> noted that kibitz expects
+		to find write in /bin but it is in /usr/bin on Slackware.
+		Seems safe to drop the prefix.
+
+		Steve Lee <steve@tuxsoft.xcom> noted that building Expect
+		failed on Linux when built from scratch because stty ends up
+		in /usr/local/bin rather than the assumed /bin.  Added code to
+		support this.
+
+4/20/04	5.41.0	Simon Taylor <simon@unisolve.com.xau> provided fix for
+		interact -o which was completely broken by 5.40.1.
+
+4/6/04	5.40.1	Added scroll support to official tkterm.  Copied all fixes
+		from/to term_expect to/from tkterm.
+
+		Kiran Madabhushi <maskiran@hotmail.xcom> encountered interact
+		diagnostics incorrectly pointing to expect_background.  Also,
+		found multiple -o flags behaving unexpectedly.  Added diag.
+
+		Kristoffer Eriksson <ske@pkmab.xse> noted typo in SIMPLE code
+		in exp_inter.c.  However, this is extremely unlikely to affect
+		any machines.
+
+		Reinhard Max <max@suse.xcom> noted that "make test" failed when
+		run in the background.  The log testcase was testing the
+		send_tty command.  Added code in both Expect and in the test
+		to handle this.
+
+1/30/04	5.40.0	Eric Raymond <esr@snark.thyrsus.xcom> provided troff-related
+		fixes for the expect, lib, and dislocate man pages.
+
+		Rich Kennedy <rickenne@cisco.xcom> noted a bug having to do
+		with our caching of whether we have registered a filehandler.
+		This broke when Tcl was setting a handler on the same file.
+
+		Ken Pizzini <ken.pizzini@explicate.xorg> provided patch for
+		leak in spawn error handling.
+
+	 	Pete Lancashire <plancashire@columbia.xcom> noted autopasswd
+		example broke on Solaris which capitalized prompts.
+
+7/31/03 5.39.0	Poorva Gupta <poorva@cup.hp.xcom> noted that grantpt/unlockpt
+		order was backward.  Strange that this was never a prob before!
+
+		Andreas Kupries <andreask@pliers.activestate.xcom> noted that
+		in exp_command.c, Tcl_GetChannelHandle expected a ClientData*,
+		but got an int*. sizeof(int) != sizeof(ClientData) on 64bit
+		platforms. Crashed the command on a PA-RISC 2.0 machine with
+		--enable-64bit set. Fix: Use temp. variables of type ClientData
+		to retrieve the fd's, and copy this into the actual variables,
+		with a cast to int.
+
+		More fixes from Andreas to sync this version with SF.
+		Fixed: exp_chan, weather, exp_main_tk.
+
+		Eric Raymond <esr@snark.thyrsus.xcom> provided a troff-related
+		fix for the multixterm man page.
+
+7/29/03 5.38.4	Nicolas Roeser <n-roeser@gmx.xnet> noted confusion with md5 so
+		I made the Expect page more explicit about which file that hash
+		was based on.		
+
+7/11/03 5.38.3	Josh Purinton noted that earlier fix wasn't quite right.  Exit
+		on INT/TERM should cause Expect to exit with signal embedded in
+		status.  He also requested I obfuscate email addresses in this
+		file.
+
+7/7/03	5.38.2	Guido Ostkamp <Guido.Ostkamp@t-online.xde> and Igor Sobrado
+		<sobrado@string1.ciencias.uniovi.xes> noted that fixline1
+		rewrote scripts to be expect scripts even if they were expectk
+		scripts.
+
+5/27/03	5.38.1	Dirk Petera <dirkpetera@yahoo.xcom> noted that any_spawn_id
+		used to work but did no longer.  Looks like a bug left over
+		from the the I18L conversion.  Fixed.
+
+		Steve Szabo noted exp_log_file -open channel failed.  Fixed.
+
+		Fixed bug from 5.31 that prevent stty from returning messages
+		from underlying program.
+
+		Thomas Dickey <dickey@herndon4.his.xcom> noted that ncurses
+		ignores 2-char term names because of, well, poor assumptions
+		and coding.  Changed tkterm to use longer names.
+
+		Heath Moore <hmoore@systran.xcom> noted that exp_clib could
+		lock up if remtime happened to be precisely 0.  Recoded to
+		avoid.
+
+		At request of Per Otterholm <otterholm@telia.xcom>, wrote
+		script to read from stdin and echo passwords (exercise 9 in Tk
+		chapter of Expect book).  Added to example directory as
+		passwdprompt.
+
+		Josh Purinton <josh@purinton.xorg> pointed out that
+		by default, SIGINT/TERM should cause expect's return status to
+		be 1, not 0.
+
+		Paul Reithmuller <paul.reithmuller@eng.sun.xcom> noted that
+		unbuffer shouldn't postprocess its output.  Added stty_init.
+
+		Mordechai T. Abzug <morty@sanctuary.arbutus.md.xus> noted that
+		log_file wasn't recording -append status.
+
+		James Kelly <macubergeek@comcast.xnet> noted weather example
+		needed new source.
+
+		Dimitar Haralanov <mitko@tahoenetworks.xcom> noted that
+		interact dumped core with interact { timeout 1 }
+
+7/18/02 5.38.0	At request of Hugh Sasse <hgs@dmu.ac.xuk> added md5 hash of gz
+		to homepage.
+
+		Dave Schooler <dave@stashtea.xcom> reported that send -s wasn't
+		handling certains chars correctly.  Turned out to be those
+		that had multibyte UTF8 reps.  send -s was just pumping out
+		hunks of bytes without regard to UTF boundaries and evidentally
+		Tcl's I/O engine thought that it should translate a partial
+		UTF8 character into, uh, something else.
+
+		Curt Shroeder <c.schroeder@computer.xorg> fixed bug in rftp - a
+		a filename looked enough like a 3-digit diagnostic that the
+		script got confused.
+
+4/16/02 5.37.2	Multixterm couldn't find man page all the time.
+
+4/16/02 5.37.1	Made multixterm handle user-supplied args.
+
+4/15/02 5.37.0	Added multixterm to example directory.
+
+4/8/02	5.36.1	Backed out CONST qualifiers.  Too much trouble with older
+		versions of Tcl.  I'll let someone else worry about them.
+
+4/8/02	5.36.0	Made first cut at multixterm, a replacement for crlogin.
+
+		Fixed bug in background handler.  If an action waited on the
+		same spawn id, esPtr would become invalidated.
+
+		Ryan Schmidt <rschmidt@mac.xcom> noted configure didn't
+		recognize MacOS X.  Downloaded new config.guess.
+
+		Andreas Kupries <andreask@activestate.xcom> provided CONST
+		patches to accomodate Tcl changes per TIP 27.
+
+2/25/02 5.35.0	Joe Eggleston <joe@arbor.xnet> noted bug in full_buffer test.
+		The test hadn't been I18'd properly and was testing chars
+		instead of bytes.  Also fixed diagnostics so it printed when
+		it was testing full buffer even if there wasn't one.
+
+2/7/02	5.34.1	Bruce Hartweg <brhartweg@bigfoot.xcom> noted that direct spawn
+		ids were not being tested so something like "expect -i exp9999"
+		would dump core.  Evidentally a bug from the 5.31 transition.
+
+12/20/01 5.34.0	Don Porter <don.porter@nist.xgov> provided package-related
+		fixes for test suite.
+
+		Brian Theado <brian.theado@usa.xnet> noted that interact's -re
+		support broke when offsets kicked in.  Turned out that the
+		regexp engine supports them during execution but the results
+		are delivered RELATIVE to the offset.  (I suspect this was done
+		due to expediency.)
+
+10/1/01 5.33.0	<mark@doradosoftware.xcom> found that expect's diagnostics
+		didn't include the "no" after testing for a full buffer.
+
+		Hemang Lavana <hlavana@cisco.xcom> noted that "debug" (Dbg_On)
+		calls didn't always force the debugger into step mode.
+
+		Martin Kammerhofer <dada@sbox.tugraz.xat> noted that the man
+		page neglected to document interpreter -eof.
+
+		Chris Clare <clarec@nortelnetworks.xcom> provided fix for
+		multiple decl in C lib.
+
+		Sheng Wang <wangs@sh.bel.alcatel.xbe> found interact's
+		can-match code had broken.  It was missing the special hook
+		that Henry had added just for this purpose.  How strange.
+
+		Dieter Fiebelkorn <dieter@fiebelkorn.xnet> requested addition
+		to config.guess for Power*Macintosh:Darwin for MacOSX.
+		Aside - to download latest config.guess:
+		 cvs -d :pserver:anoncvs@subversions.gnu.org:/cvs co \
+		 autoconf/config
+
+		Added pipeline example to unbuffer man page.
+
+8/4/00 5.32.2	Allen J. Newton <anewton@alturia.fleet.xorg> provided code for
+		generating passwords with special characters in mkpasswd.
+
+		Brent Welch <welch@ajubasolutions.xcom> changed the fix1line
+		install script so that "autoexpect" and other scripts that
+		get installed into the platform-independent bin directory
+		generically invoke "expect" from the users PATH instead
+		of hardwiring the platform-specific expect pathname.
+
+		TclPro 1.4 released with 5.32.2 bundled.
+
+7/13/00	5.32.1	Uwe Klein <uwe-klein@foni.xnet> reported segfaults from reading
+		nulls.  Due to code rewrite in 5.30->5.31 transition.
+
+5/14/00 5.32.0	New version for timing with Ajuba TclPro 1.4.  This version
+		of Expect has no new features or behaviors but a lot has been
+		fixed since 5.31.0.
+
+		Martin Buchholz <martin@xemacs.xorg> noted that his
+		alphaev56-dec-osf4.0e has ptmx and ptmx_bsd (and ptm, pts,
+		pty, ptym).  He suggested that BSD things are now usually
+		deprecated so to skip ptmx_bsd if ptmx avail.
+
+		Chang Li <changl@neatware.xcom> noted that debugger's bp cmd
+		broke on every command.  Was a bug in breakpoint_trace from
+		when we installed the new regexp engine.
+
+		Jonathan Kamens fixed printf formats in several pty diags.
+
+		rm_nulls -d was set to wrong value.
+
+5/12/00 5.31.8	After receiving yet another request for fully versioned
+		archives, gave in.
+
+		Signal handler sometimes sent error to stderr inappropriately.
+
+4/27/00 5.31.7	Rob Savoye fixed Debian ptys and properly checking of libpt.
+
+3/8/00  5.31.6	Petrus Vloet <petrus.vloet@siemens.xat> noted that Expect
+		installed tclRegexp.h which included regex.h which of course
+		misbehaves when it reads the system's version.  This is new
+		since 8.0.  Since I need to revise the Clib anyway (which
+		is what this install was for), I'll back this out for now.
+
+3/6/00	5.31.5	Larry Virden noted that configure checked for threads twice.
+
+2/19/00 5.31.4	Omer Azmon <oazmon@telsoft-solutions.xcom> note errors in
+		pty_termios.c in exp_pty_test that caused problems during
+		pty testing.
+
+		Jeffrey Hobbs recommended having configure accept and warn
+		about --enable-threads.
+
+		John Ellson <ellson@lucent.xcom> noted configure's autoconf
+		testing had leftover debugging code.  Also provided a fix for
+		building w/shared libs on HP - appeared to be leftover from
+		earlier Tcl-required configuration that has now disappeared.
+
+		Susan Muston <smuston@crosskeys.xcom> noted that exp_wait with
+		no spawned processes exited immediately which is different
+		than 5.29 behavior which reported "no children".  This new
+		behavior was evidentally a gratuitous change during the
+		channel driver addition.  Backed out.  At the same time,
+		neither behavior matches documentation - doc should be fixed
+		and improved except I'm not sure if the behavior should yet
+		be something else (depending if stdin closed or not).
+
+		istvan.nadas@epfl.ch reported "spawn cat;exp_open" failed.
+		Uninited variable.
+
+		Scriptics reported memory leak.  Was bug in parse_expect_args.
+
+		"Michael P. Reilly" <arcege@shore.xnet> noted clib was hanging
+		in spawn code.  status_pipe wasn't being closed.
+
+		Egil Kvaleberg <egil@kvaleberg.xno> provided fix due to new gcc
+		which defines strchr as a macro.
+
+		Dave Morrison <drmorris@corp.phone.xcom> noted some printfs
+		in exp_log.c that misinterpreted embedded %'s with resulting
+		core dumps.
+
+		Dick Goodwin <goodwin@qosnetics.xcom> noted that "system echo
+		foo" returned with no apparent effect.  Due to closeonexec
+		in expect's channel driver.  Added skip if std channel.
+		Fixed similar bug in stty command.  Minor bug left in stty
+		which isn't passing output back from underlying exec.
+
+		Stacy W. Smith <stacy@ixc-comm.xcom> provided patch that uses
+		sigsetjmp instead of setjmp that he says fixes a problem he
+		encountered with C lib where it stopped timing out in expect()
+		as if the signals were corrupted.  The man page doesn't
+		explain the difference between these calls in a way that makes
+		sense as to why they should make a difference, but I'll the
+		names are certainly suggestive so I'll try it.  He says "it
+		  appears that the linux setjmp behaves a little differently
+		  compared to setjmp on some other OSs.  Specifically, setjmp
+		  on linux does not save the signal context.  It seems most
+		  BSDish OSs do save the signal context with setjmp.  On those
+		  machines, it appears setjmp(env) is equivalent to
+		  sigsetjmp(env,1) whereas on linux, setjmp(env) is equivalent
+		  to sigsetjmp(env,0).  My patch made a (probably bad)
+		  assumption that if siglongjmp() exists that we should use
+		  the sigXXX versions.  I specifically tested for siglongjmp 
+		  rather than sigsetjmp because on linux, sigsetjmp is just a
+		  #define for  __sigsetjmp.  It appears that linux will give
+		  the BSD behaviour if  __FAVOR_BSD is defined, but I didn't
+		  know what other implications that might have.
+
+		Michael Schumacher provided fix so that test for whether
+		configure was out-of-date worked when not using the default
+		build dir.
+
+11/1/99 5.31.3	Shlomi Mahlab <shlomi@seagull.co.xil> noted all.tcl in CVS
+		but not distribution.
+
+		More notes from Keith Brown on HP cc complaints in exp_pty.c.
+
+10/28/99 5.31.2	"Keith Brown" <surely@nortelnetworks.xcom> noted that HP cc
+		objected to auto aggregate initialization in
+		expLogChannelOpen.
+
+10/22/99 5.31.1 Official release!
+
+		P Darcy Barnett <pdb@cam.nist.xgov> noted Makefile could
+		produce "autoconf not found" for non-developers using CVS.
+		Made configure detect and provide advice on workaround.
+
+		Fixed bug in interact -echo exhibited in rftp example.
+
+		Ryan Murray <rmurray@cyberhqz.xcom> noted Expect wasn't
+		handling handling 8-bit bytes correctly.  I had accidentally
+		used Tcl_Write instead of Tcl_WriteChar.
+
+		Ashley Pittman <ashley@ilo.dec.xcom> noted that digital unix
+		V5.0 prefers openpty (4000 ptys) over ptmx (60 ptys), so I'm
+		reversing the login in pty_termios.c.  This also controls
+		linux, but no linux hackers have weighed in on this subject
+		yet.
+
+		Andrew Tannenbaum <trb@world.std.xcom> noted exp_internal
+		command and "expect -exact" were broken.
+
+6/29/99 5.31.0	See the NEWS file for this date for an overview.  (I'm
+		too tired to add all the details.  Maybe later.)
+
+		Fixed exp_clib so that it immediately reported failure of
+		exec (in spawn) rather than passing it back through pipe.
+
+		Removed error checking from ioctl(TIOCSCTTY) to pacify the
+		variety of (but not all) Linux systems and a few others which
+		define TIOCSCTTY but return an error although seem to work
+		anyway.
+
+		Added configure test for 0 vs 2-arg setpgrp.
+
+		Kenji Kamizono <kenji@math.columbia.xedu> noted it was possible
+		to compile Linux (2.2.5) so that it recognized both openpty
+		and ptmx leading to conflicts.  I arbitrarily chose ptmx.
+
+10/15/99 5.30.2	Herve Tireford <tdes46@email.sps.mot.xcom> noted extraneous
+		sleep(20) in clib.  Apparently left over from debugging, oops.
+
+8/18/99 5.30.1	Added test for newer versions of Tcl that are incompatible.
+
+		Kenji Kamizono <kenji@math.columbia.xedu> noted it was possible
+		to compile Linux (2.2.5) so that it recognized both openpty
+		and ptmx leading to conflicts.  I arbitrarily chose ptmx.
+
+4/1/99	5.30.0  Martin Forssen <maf@crt.xse> provided fix to allow configure
+		to start with LDFLAGS from environment.
+
+		Paul Tazzyman <Paul.Tazzyman@one.xat> noted that log_file
+		didn't check for logging twice without turning off logging
+		first.
+
+		Ben <spy@calvin.iconoclasm.xorg> provided updated host for
+		weather example.
+
+		Jonathon Kamens noted that Expect didn't build properly if
+		Tcl and/or Tk used build/install directories out of the usual
+		hierarchy.  At the same time, I fixed a number of other related
+		problems in Makefile/configure.
+
+		Pierre Pomes <ppomes@it.marseille-innov.assoc.xfr> provided fix
+		to ftp-inband.  It blew up from an unprotected send that
+		was handed a uuencoded line that started with a -.
+
+		Autoexpect was thrown off by simple-minded file executable
+		test picking up expect directory while searching for
+		executable.
+
+1/21/99 5.29.0	Martin Forssen provides mods to support INSTALL_ROOT.
+
+		Bryan Surles <surles@scriptics.xcom> modified configure.in to
+		map DBGX to the same value as TCL_DBGX so the .so is named
+		correctly.
+
+		Suresh Sastry <suresh@scriptics.xcom> forced $LIBS to be
+		added to EXP_SHLIB_LD_LIBS.  It's not clear to me why this is
+		necessary (since Tk doesn't) but he was having a problem
+		with openpty not being found during runtime on Linux.
+
+		Martin Forssen noted expectk was crashing if a Tcl error was
+		encountered.  He found that exp_exit_handlers() was trying
+		to write into interp->result after interp had been deleted.
+
+		Added another copy to distribution site - with version number.
+
+		Stanislav Shalunov <shalunov@mccme.xru> closed race in pty
+		code.
+
+		Fixed man page: -brace should be -nobrace.
+
+		Dan O'Brien <dmobrien@lucent.xcom> noted that Expect needed to
+		call Tcl_FindExecutable at startup for info nameofexecutable.
+
+		Robbie Gilbert <rwg@nc.fnc.fujitsu.xcom> noted indirect spawn
+		ids occasionally failed.  Fixed.
+
+9/30/98	5.28.1	Brian France <franceb@fsj.co.xjp> noted that his compiler
+		rejected label with no statement.
+
+9/28/98	5.28.0	Fixed two bugs in tcl-debugger (see that HISTORY file).
+
+		Submitted Expect documentation for official NIST review.  At
+		their request, modified a couple things.
+
+9/21/98	5.27.0	Added support for Tcl 8.0.3.  Simple compiles already work
+		fine but exotic things break.  In particular, Expect needed to
+		understand new TCL_DBGX feature.  Massaged debugger interface
+		which was recently revised.
+
+		Karun Krishnaswamy <karun@transarc.xcom> noted that pine didn't
+		run in term_expect.  The problem was that pine uses curses
+		(or terminfo) directly (!!) and insists on clear-to-eol	(a
+		really dumb thing to insist on since it's so easily emulated).
+
+		bert@xpilot.org (Bert Gijsbers) (of xpilot fame) provided patch
+		to passmass to handle ssh protocol and explanation of how to
+		create new password entries.
+
+6/15/98 5.26.1	Dean Sauder <dsauder@dcn.att.xcom> noted C-preprocessor lines in
+		configure must start in column 0.
+
+5/18/98 5.26.0	Kevin Schleicher <kms@lucent.xcom> noted xkibitz leaves xterms
+		if first xterm is HUP'd.  Kevin also noticed a resource leak
+		in dislocate.  Both problems fixed.
+
+		Robbie Gilbert <rwg@fns.xcom> noted expect_devtty was logging
+		devtty (twice) to stdout.  Fixed.
+
+		Added support inttypes.h, required on Solaris 5.6 for termios.h
+
+		Kristina  <kristina@greatbasin.xnet> noted that tip failed when
+		spawned from a cgi script (BSDI BSD/OS 3.1 i386) because tip
+		didn't see a definition for SHELL and HOME.  They need to be
+		set.  (Doesn't have to be anything useful; the empty string is
+		fine!)  Solution: documented this in Expect man page.
+
+		Zachariah Baum <zack@studioarchetype.xcom> noted that
+		config.sub didn't recognize Intel 686.  Found a newer version
+		that did in autoconf-2.11.
+
+		POTENTIAL INCOMPATIBILITY: Changed interact so that it observes
+		parity while matching.  It used to ignore parity.  This impacts
+		people who use interact to connect through to a real serial
+		device that generates parity.  If matches don't work, use the
+		exp_parity command.  (This fix should have been made years ago,
+		when the exp_parity command was added.  It is now absolutely
+		necessary now that people are doing matching with 8 bits.)
+
+		After the second occurrence of a system admin who broke grantpt
+		by removing setuid from the relevant system util, I added an
+		explicit test and explanation.
+
+		Disabled history in xkibitz.  There seems to be some new
+		incestuous relationship between history and unknown now so that
+		redefining unknown leaves Tcl calling history but without
+		knowing what it is because it's never been defined (as it would
+		be by the traditional unknown).
+
+		Fixed quoting bug in passwd.cgi example. 
+
+9/28/97	5.25.0	Switched back to hand-generating pkgIndex.tcl file after too
+		many complaints about problems running pkg_mkIndex.
+
+8/12/97 5.24.1	Chris Schanzle <chris@goof2.ncsl.nist.xgov> pointed out that
+		install fails on a virgin file system because install_shared_
+		lib depends on a directory that hasn't yet been created.
+
+		Larry Virden gave corrections to URLs in README.
+
+8/21/97	5.24.0	Bo Johansson <bo.johansson@mbox2.swipnet.xse> noted TclWordEnd
+		had changed and provided fix.  This caused crash in expect.
+
+8/18/97	5.23.0	This version supports Tcl 8.0 and continues support for 7.6.
+		Refs to Tcl_Files dropped.  inter_return and close became
+		obj cmds.  Rewrote notifier (again) to accomodate new notifier
+		model.  Lots of other miscellaneous tweaks.  Also see debugger
+		HISTORY file.
+
+		Finally removed long-deprecated commands "continue -expect",
+		"send_spawn", and "getpid" and their exp_ versions.
+
+		Harold Brauer <harold.brauer@canada.cdev.xcom> reported problem
+		with an old SCO system (i386-unknown-sco3.2v5.0) that turned
+		out to be due to a typo in the configure script.
+
+		Jimmy Aitken supplied mods to config.guess for brand new and
+		very old Pyramid systems.
+
+		Buz Owen noted memory leak in use of expect_background (with
+		no args).
+
+		Jonathon Kamens noted provided patch for pty_termios.c for
+		modern Sequent (which ptmx).
+
+		Jonathon Kamens noted that TCL defined RANLIB for shared lib
+		(if --enabled-shared) which isn't appropriate when Expect tries
+		to build both shared and unshared libs.
+
+		Jonathon Kamens noted that shared lib config didn't work on
+		SunOS.  I had used Tcl's SHLIB_SUFFIX instead of its
+		SHARED_LIB_SUFFIX.
+
+		Qingyi Liao <liao@casabyte.xcom> encountered core dump when
+		exp_bg -i $exp_spawn_any was retracted.  Bug in ecmd_remove_fd.
+
+		Fixed a bunch of bugs in example/gethostbyaddr.
+
+		Josef Sachs noted that stty cannot be caught when no /dev/tty.
+		It calls exit instead of returning an error.
+
+		Gordon Chaffee <chaffee@plateau.CS.Berkeley.XEDU> patched
+		Exp_WaitCmd - it was zeroing pid element instead of wait.
+
+		Bob Manson <manson@cygnus.xcom> provided fix for HP on which it
+		was possible for timer to be mistakenly deleted in
+		exp_get_next_event while processing a pty open event.
+
+		Jeff Slonaker <JSlonaker@osc.uscg.xmil> noted that exp_poll.c
+		had wrong signature and poll had arguments out of order!  That
+		would suggest that no one has ever used exp_poll.c before...
+
+	5.22.1	Larry Virden noted that TCL_BUILD_LIB_SPEC can't be used if
+		build directory has been removed.  Added check to configure.
+
+		Worked more on package command.  Buz Owen pointed out that my
+		code wouldn't support redefinition of TCL_LIBRARY.  Bumped up
+		minor version to avoid package loading mishaps.
+
+		Nigel Standing <nigel@idiom.xcom> noted lack of C-u binding in
+		tkpasswd - must be due to change in tk4.2.
+
+		Forced env(SHELL) to be defined inside kibitz for when using
+		with CGI.
+
+		Charles Packer <packer@fermi.gsfc.nasa.xgov> noted that
+		CRAY-YMP needed sys/types.h in exp_console.c
+
+		Extra / when developing defn of TCL_LIBRARY.  Shouldn't
+		actually cause any problems though.
+
+2/3/97	5.22.0	Fixed package support - again.  Sigh.
+
+		David Pasirstein <dpasirst@sun.cs.wcupa.xedu> noted that RedHat
+		Linux 2nd passwd prompt requires slightly different pattern -
+		modified mkpasswd and tkpasswd.
+
+		Toshiaki Nomura <nom@yk.fujitsu.co.xjp> provided patch to
+		config.guess for Fujitsu DS/90.
+
+		Roger Brooks <R.S.Brooks@liverpool.ac.xuk> noted C lib passed
+		argv0 instead of file to first arg of execvp.
+
+		Cary D. Renzema <caryr@mxim.xcom> noted that a simple puts -nnl
+		might never appear - Expect closes all of its fds before Tcl
+		gets a chance to flush.  Stdout is the obvious problem since
+		Expect thinks it can cavalierly close that too.  Hmm.
+
+		At request of Tom Tromey, solved possible missing tclRegexp.h
+		problem by having Expect install it.  Cleaned up TCLHDIR and
+		TCL_LIBRARY hackery in Makefile.
+
+12/27/96 5.21.7	Nelson Beebe noted unset is not portable in /bin/sh.  Removed
+		and converted everything to understand CONFIG_SHELL.
+
+		Modified cryptdir to strip out shell metachars from filenames.
+
+12/10/96 5.21.6	Michael Schumacher noted that some systems cannot build
+		unshared libs from shared objects.  Chose to go with BLT's
+		approach of building shared objs in separate shared directory.
+
+		Buz Owen <ado@bbn.xcom> noted that "package require Expect"
+		didn't work because it looked for Expect lib in the wrong
+		place (well, the "documented" place).  The problem is that Tcl
+		insists libraries should be in the same directory as the
+		pkgIndex.tcl file while the natural thing to do would be to
+		split them up and put the .tcl file in the arch-indepent
+		app-specific scripts dir and the lib in the arch-dependent
+		common dir.  Sigh.  If this is ever fixed/changed, the
+		instructions in the Makefile should be fixed.
+
+		<Van.Trinh@siemenscom.xcom> noted that expect library name
+		exceed filename max on some systems - like his old SCO.
+
+12/4/96	5.21.5	Michael Schumacher noted new configure wasn't passing on Tcl's
+		shared lib cflags.
+
+10/26/96 5.21.4	Achyutram Bhamidipaty <ram@epic.xcom> ran into bugs in Expect's
+		file event handler which prevented expectk from entering
+		implied event loop.  Also found one memory problem - thanks
+		to CenterLine.
+
+		Tom Tromey fixed handling of --enable-shared when overriding
+		Tcl's value et al.  Tom also added missing "else true" to
+		Makefile: "In a Makefile, you have to always supply an "else"
+		clause for an "if", to work around a bug in certain versions of
+		sh.  In some versions of sh, an "if" whose test fails will
+		return the status of the test if there is no "else" clause --
+		causing spurious make failures."  See ChangeLog.
+
+10/18/96 5.21.3 Example directory was missing several examples.
+
+10/17/96 5.21.2 Debugger section of configure file corrupted.
+
+10/10/96 5.21.1	Oops, distribution unpacked into wrong version.
+
+		Tom Tromey provided patch for stty to understand OSF 4.0.
+
+9/28/96	5.21.0	Official Expect release for Tcl 7.5.
+
+		Junio Hamano <junio@twinsun.xcom> provided fixes for aclocal
+		for with_tcl/tkconfig.
+
+		Roger Billau <rfbilla@amtnet.sandia.xgov> noted that C library
+		didn't work on Solaris 2.5.  Turns out Solaris requires fflush
+		be called between input and output operations on FILE pointers.
+
+		Lots of Cygnus mods - see ChangeLog.
+
+		Sid Cowles <scowles@incyte.xcom> and Hans Riethmann
+		<hans@F1.telekurs.xch> noted relative path specs of
+		tcl-includes (and others) caused debugger config to fail since
+		it is at a different directory level.
+
+		Al Snow <asnow@fuwutai.att.xcom> noted -C failed due to typo.
+
+8/17/96 5.20b18	Andrew Rakowski <andrew.rakowski@nr.usu.xedu> noted no defn of
+		LIB_RUNTIME_DIR, a creation of Tcl7.5p1.
+
+		Tom Tromey added -v to Expect and -version to Expectk.
+
+		Ben Boule <bboule@xylogics.xcom> noted that Interactive (IUNIX)
+		requires 9 char max length after -l.  Looks like squeezing out
+		the "." is sufficient.  He also noted that IUNIX needs -Xp in
+		LIBS to find strftime.  This test should really be done by Tcl.
+
+8/12/96 5.20b17 Glen Biagioni <glen@prosoft.xcom> noted interact -re "A(xx)"
+		failed to match.  Problem turned out to be that Tcl 7.5 changed
+		a constant which in the regexp code, which Expect didn't see
+		because it provides its own defn for interact.  Alas, the one
+		thing Expect reuses from Tcl was where the change was.  This
+		should really be fixed so Expect doesn't rely on Tcl in this
+		way, but there's no point in putting in a lot of work on regexp
+		when we're anticipating a new one soon anyway.
+
+		Bjorn S. Nilsson <nilsson@nbivms.nbi.xdk> noted fixcat hangs.
+		Turned out that new Tcl (7.5p1) now waits for all children to
+		disappear.  But Expect still had a handle to a child.  I added
+		an exit handler to close the connections before Tcl's exit
+		handler.
+
+		Tom Tromey provided patch to support augmenting CFLAGS on
+		Makefile invocation.
+
+		Gary Merinstein <gmerin@panix.xcom> noted that configure failed
+		on his linux unless it had --enabled-shared.  Not quite sure
+		about how this can be, but the flag wasn't being passed to the
+		debugger's configure, so I've fixed that and hopefully this
+		will cure the original prob.
+
+		Added initial announcement of full version at beginning of
+		configure.  This should ease my pain in responding to people
+		sending me config output without including version numbers.
+
+		Tom Tromey noted expect_cf.h was machine dependent.  Fixed
+		expect_comm.h so that it no longer required expect_cf.h (which
+		should be renamed to indicate it is no longer public).
+
+		Bart Robinson <lomew@cs.utah.xedu> provides mods to support
+		openpty() in FreeBSD/NetBSD.  Without openpty, Expect doesn't
+		see the full pty namespace (ptyX0-v).
+
+7/15/96 5.20b16	Nathan Estey <nfe@the-hermes.xnet> noted that Makefile failed
+		on SunOS when shared libs were enabled due to incomplete dot
+		stripping in lib prefix.
+
+7/6/96	5.20b15	Malcolm Tredinnick <malcolmt@geko.net.xau> noted that shared
+		lib has to be installed before building expect.  Also noted
+		that ldconfig should be run on Linux 2.0 systems and maybe
+		others.
+
+6/25/96 5.20b14 Tim Mooney provided fixes to obey --includedir and similar
+		configure conventions.
+
+6/25/96 5.20b13	A bug when installing Expect using new _installed targets.
+
+6/24/96	5.20b12	Numerous complaints from Solaris users about shared libraries.
+		Unfortunately, no one is giving me configure-ready fixes so
+		(and Tk's configure seems to have bugs as well) so fixing
+		these is like throwing darts.
+
+		Stan Brown <stanb@netcom.xcom> noted noidle example broke when
+		fed "-".
+
+		Gordon Irlam <gordoni@cygnus.xcom> noted typo in install-sh.
+
+		David Sheinberg <sheinb@bcmvision.neusc.bcm.tmc.xedu> noted no
+		args test for spawn -open/leaveopen.
+
+		Misc patches from Tim Mooney to pacify much of gcc -wall.
+
+		Kayvan Sylvan insists Linux stty reads from stdin so added
+		hardcoding to configure.in for that.  In xkibitz, Linux stty
+		-raw didn't disable all post-processing.  How odd that it is
+		not a problem in interact.  In the meantime, added extra stty
+		to xkibitz to do what was missed.
+
+5/30/96 5.20b11	Kayvan Sylvan <kayvan@sylvan.xcom> noted quoting bug in
+		autoexpect.
+
+5/22/96 5.20.b10 Patches from Larry Virden in Makefile.in and exp_int.h
+
+5/20/96 5.20.b9	Too many substitutions in configure caused sed failures on
+		DEC (limit 99) and HP (100).  Commented out definitions
+		that weren't absolutely critical.  Hopefully, this gets us
+		under the limit but can't be sure since there's no easy way
+		of knowing.
+
+		Numerous mods from Mark Diekhans to support clist-style	ptys
+		on SCO OpenServer.  (He says SVR4 ptys are broken on that
+		platform.)
+
+		Simon J. Gerraty <sjg@zen.void.oz.xau> says that write()
+		returns	0 inside of exact_write on SunOS.  This is outside the
+		SunOS spec so of course we have no idea what's going on.  So I
+		added code to try and recover from (or at least warn of) this.
+
+		Tom Tromey unified decls of errno to #includes.
+
+5/13/96	5.20b8	Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.xedu> pointed out
+		backwards stty test - this would have corrupted every platform!
+		He also pointed out that alpha-dec-osf3.2  (3.2c) complained
+		too many args to sed.  Someone earlier said similarly about
+		HPUX 10, but I assumed it was the quotes in the weird stty
+		flag I was passing, so that "fix" wasn't.  GNU sed has no
+		problem, but obviously this is not sufficient for many people.
+
+5/10/96	5.20b7	Renamed/numbered versions so that it's easier for others to
+		track.
+
+		Upgraded to autoconf 2.10.
+
+		Matthias Kurz <mk@baerlap.north.xde> noted Makefile problems
+		with final Tcl7.5.
+
+		Blair Zajac <blair@gps.caltech.xedu> noted configure mishandled
+		stty defaults on HP and shared lib must be installed executable
+		on HP.
+
+		autoconf insists on adding -O to CFLAGS when using gcc.  Ack!
+
+3/23/96 5.20b1	Beta release 1 of Expect for Tcl 7.5.
+
+		Michael Hunter <mphunter@qnx.xcom> provided misc mods for QNX.
+
+		Various people reported problems with IRIX.  Removing from the
+		stty list fixed the problem.  Similar problem with Solaris.
+
+		Added explicit close to autoexpect.  Added a mechanism for
+		enabling conservative mode after script is generated.
+
+		Hal Schechner <hal-j@netusa.xnet> pointed out passwd.cgi must
+		meet passwd's requirement that it not be run by an unrelated
+		user.  Easy enough - just do an su first.
+
+3/26/96 5.20a5	Alpha release 5 of Expect for Tcl 7.5b3.
+
+		Added example passwd.{html,cgi} to change a password.
+
+		Many fixes from Stephen Williams <steve@icarus.xcom>
+		and Jonathon Kamens for Makefile and configure.
+
+3/22/96 5.20a4	Alpha release 4 of Expect for Tcl 7.5b3.
+
+		Added version number to lib directories (POTENTIAL
+		INCOMPATIBILITY).
+
+		Revised gethostbyaddr example - evidentally hadn't worked for
+		some time!
+
+		Jan Nijtmans <nijtmans@nici.kun.xnl> provided pkgIndex.tcl.in.
+		Renamed Exp_Init to Expect_Init to support package cmd.
+		Provided #define so that Exp_Init will continue to work.
+
+		Revised exit handling so that it works if Expect is dynamically
+		loaded.
+
+		aclocal.m4 Patches from Tom Tromey.
+
+3/15/96	5.20a3	Alpha release 3 of Expect for Tcl 7.5b3.
+
+		Edward Haletky <elh@astroarch.xcom> noted that Machten required
+		inclusion of types.h in exp_tty_in.h.
+
+		Added various patches from Rob Savoye.  One incompatibility
+		is that the static lib now ends with the version number.
+
+		Added support for TCL_SHLIB_{LD_LIBS,VERSION} in Tcl b3.
+
+		Jonathan Karges <J.Karges@dkfz-heidelberg.xde> found that clib
+		was timing out immediately on -1.
+
+3/6/96	5.20a2	Alpha release 2 of Expect for Tcl 7.5b2.
+
+		Leland Joseph <leland@tec.tetd.bellcore.xcom> noted
+		expect-tests.exp exceeds the 14 character filename length.
+
+		Added config.{sub,guess} to support AC_CANONICAL_....
+
+		Rewrote much of aclocal, configure.in, and Makefile.in
+		to handle Tcl/Tk config.sh files and shared/dl support.
+
+		Simplified varargs/stdarg mess for Expect's C library.
+
+		Threw away closetcl junk.  No longer required because
+		Tcl finally started doing close-on-exec.
+
+		Incorporated various fixes from Tom Tromey at Cygnus.
+		See ChangeLog for details.
+
+		Added require/provide support.
+
+		Rejiggered event handling to support new Tcl_File interface.
+
+		Removed libexpectk.  Because event loop was moved into Tcl, it
+		is no longer necessary for it to be different than libexpect.
+
+		Removed all support for earlier versions of Tcl and Tk.
+
+		Numerous misc patches from Paul Eggert <eggert@twinsun.xcom>
+		most to support Tcl 7.5.
+
+		Arnold Robbins supplied yet another patch to fix earlier
+		problem noted by Hume Smith.
+
+		David Engel <david@ods.xcom> reported problem with Linux
+		dumping	core.  CenterLine, of course, immediately found the
+		problem - uninit'd lowercase buffer.
+
+		Peter Haggerty <haggerty@borg.lib.vt.xedu> noted that his Next
+		died in cron.  It seems that Next doesn't support O_NOCTTY
+		(even though the man pages says it does) and so during pty
+		testing, control terminal would get allocated and then kill
+		the process (by generating a HUP) when deallocated.  Avoid
+		by ignoring HUP when doing pty testing on such machines.
+
+1/3/96	5.19.0	Fixed bug that made expect report wrong string when using
+		a terminating anchor in a positive-length glob match,
+		reported by Graham L. Randall <grandall@nit.airtouch.xcom>.
+
+		Added rlogin-display to included examples.  rlogin-display
+		automatically propagates your $DISPLAY when you rlogin.
+
+		Hume Smith <hclsmith@localhost.isisnet.xcom> noted problem
+		with day of the week calc at year end/start.  Arnold Robbins
+		supplied fixes.
+
+		Jonathan Kamens provided fix to make sync byte reads
+		recover from EINTR.
+
+		Henry Spencer noted errant line of spaces in Makefile.
+
+10/21/95 5.18.1	Began adding support for tcl7.5a1/tk4.1a1.  (not finished!!)
+		- Make aclocal understand new Tcl/Tk directory layout
+		  for finding tclInt.h and private libraries.
+		- Added support for Tcl_AsyncReady.
+
+		Paul Townsend <aab@aab.cc.purdue.xedu> noted that distclean did
+		not remove some config cruft.  Also recommended unsetting
+		M*FLAGS that cause make called from configure to fail.
+
+		Various fixes from Cygnus.  See Changelog.
+
+		Deleted "-" before rm in loop in deinstall in Makefile as per
+		Doug Claar <dclaar@hprtnyc.ptp.hp.xcom>.  Doug also found prob
+		involving recent STTY fix.  Symptom was that pty wasn't
+		correctly inited in cgi scripts on HPs - and Cray pty support
+		blew up entirely.
+
+		Added exp_ prefix to tests so that they can be run with other
+		extensions.
+
+		Seth Ornstein <pp001465@pop3.interramp.xcom> noted bug in the
+		way rftp detected symlinks.
+
+		Upgraded to autoconf 2.4.  This fixes a bug in AC_PROC_CPP
+		which blew up when CPP was defined in the environment.  Noted
+		by John Pfuntner.
+
+		Jonathan Kamens noted that library didn't check return pipe()
+		return value.
+
+		Added vrfy example.
+
+		Przemek Klosowski <przemek@rrdjazz.nist.xgov> Irix 6.0 fails
+		to use ptys that have been used by someone else.  SGI admitted
+		this is a bug and the solution is to upgrade to 6.1.
+
+		Yoad Grinberg noted "expect -timeout" mistakenly ate next arg
+		as pattern.
+
+8/24/95 5.18.0	Wayne Christopher noted that the way exp_eval_with_one_arg
+		modifies the original argv makes the ICEM Tcl compiler unhappy
+		so I rewrote it to avoid that.
+
+		Ian Zimmerman <itz@rahul.xnet> found that a braced arg list of
+		a single pattern beginning with a \n caused expect to reeval
+		for multiple args twice.  I added a -nobrace flag that expect
+		and/interact can use internally to prevent this.
+
+		Florian La Roche <florian@jurix.jura.uni-sb.xde> noted a few
+		glitches in the way -ltcl was searched for in aclocal.
+
+		Joachim Posegga <posegga@ira.uka.xde> noted lack of Tcl
+		internal includes should be an error during configure.
+
+8/10/95 5.17.8	Martin Wunderli <wunderli@baloo.limmat.net.xch> found missing
+		quote in config.
+
+		Danny Faught noted problems in Makefile when passing STTY defn
+		with quotes.  Created another a STTY-less CPPFLAGS for cases
+		where additional reexpansion occurs.
+
+		Danny Faught noted bug in error handling for checking
+		permission problem with /tmp.
+
+8/1/95	5.17.7	Todd Rimmer <trimmer@mantis.ssw.xcom> noted that HP 10 with
+		optional streams package has both PTYM and PTMX which conflict
+		in pty_termios.
+
+		Rainer Wilcke provides fixes: scripts not listed as dependency.
+		distclean target used Makefile after deleting, and many fixes
+		to man pages.
+
+		Saad Mufti <mufti@hobbit.pls.xcom> noted bug in how C library
+		handled polling (when handling multiple fds).
+
+		Jeff Bowyer noted more autoexpect bugs.
+
+7/22/95 5.17.6	More features added to autoexpect (now version 1.3).
+
+		Sanjay <sanjay@clef.lcs.mit.xedu> noted bug in TCLH config
+		macro which caused it to use 7.3 instead of 7.4.
+
+		Rodney Barnett <rlb@us.teltech.xcom> noted expectd.proto had a
+		few refs to interact_out where it should've had expect_out.
+
+		Terry Rhodes <tbr@88open.xorg> noted that Expect returned a 0
+		exit status upon syntax error unlike tclsh and wish.
+
+		Fred Obermann <fredo@conan.ids.xnet> noted that Unixware 2.01
+		native development tools don't permit configure to find memcpy
+		because memcpy is handled specially by the compiler and it
+		complains when it finds configure's default test with no args.
+		Changed to a hand-crafted test with args.
+
+7/12/95	5.17.5	Jeff Bowyer <jbowyer@muni.xcz> noted minor bugs in autoexpect.
+
+		Rob Saul <robs@sco.xcom> noted that configure failed on SCO
+		OSR5 because trap requested by Cygnus (to allow config in bg)
+		used higher traps than SCO sh knows about.
+
+		Changed "can't happen" to "xmkmf is broken" when configure
+		fails to compile simple	C-Tk program.
+
+		John H. Chauvin <jchauvin@netcom.xcom> noted exp_tty_current
+		and cooked raised multiple def errors on SGI 5.3 with native
+		cc.
+
+7/9/95	5.17.4	Wolfhardt Lotz <s11@blue.lrw.uni-bremen.xde> noted Solaris
+		doesn't do case-insensitive man page lookups so I lowerized
+		the beginning of the .SH lines.
+
+		Henry Spencer noted unbackslashed quotes in the autoexpect
+		boilerplate.
+
+7/3/95	5.17.3	Modified VARARGS decls to support new Tcl 7.4 definitions.
+
+		Fine-tuned aclocal so that it would prefer later versions.
+
+		Added autoexpect example and man page.
+
+6/30/95	5.17.2	select-based dsleep() was returning an internal expect-style
+		return code instead of a Tcl-style.
+
+6/30/95 5.17.1	Kannan Varadhan <kannan@isi.xedu> noted aclocal didn't
+		look in right directories to find Tk.
+
+6/30/95	5.17.0	Modified regexp interfaces to support Tcl 7.4b4.
+
+		Mods from Tony Isles <ittony@traf.xcom> for Sequent Dynix/ptx
+		V2.1.5 (which is really old).
+
+		Michael Schumacher <hightec@rz.uni-sb.xde> noted that Solaris
+		2.4 header files require __EXTENSIONS__ for all sorts of
+		traditional but non-standard definitions.
+
+		Modified aclocal to support new Tcl/Tk library names.
+
+		George Forman <forman@cs.washington.xedu> requested support in
+		C lib for fds that already exist.  I added exp_spawnfd.
+
+		Fixed bug preventing signal rearming on Linux (using SV-style
+		signal handling).
+
+		Wayne Christopher <wayne@pmac.icemcfd.xcom> noted missing
+		interp in call to exp_error.
+
+		Added null support to interact's exact matching.
+
+		Bruce Jerrick noted INSTALL was being used rather than
+		INSTALL_PROGRAM/DATA.
+
+		Dennis Ferguson <dennis@mci.xnet> noted that on Solaris 2.4
+		close(pty) occasionally returns EINVAL.
+
+		Added tests so that if we can't get a pty, we can give the user
+		much more help with what to do about it.		
+
+		Steven Byrnes noted that Solaris has replaced TIOCCONS with
+		SRIOCISREDIR interface.
+
+		Technically speaking, interact shouldn't do buffer-shuffling
+		but I've added as a fail-safe mechanism to catch people who
+		use preposterous patterns.
+
+		Alan Heckert <heckert@tiber.nist.xgov> noted missing decl in
+		Convex pty support.
+
+		Fixed all expectk examples for Tk4.
+
+		Bryan S. So <so@cs.wisc.xedu> noted that interact -o eof failed
+		if an unbuffered pattern was partially in progress.
+
+		Added -timeout flag to expect command to override timeout var.
+
+		John Pfuntner <pfuntner@VNET.IBM.XCOM> noted that OpenMVS did
+		not notice @ inside of Makefile SETUID macro as suppression
+		but instead treated it as part of the program name.
+
+		Jim Porter <James.W.Porter@att.xcom> noted that exp_free_i
+		freed the variable name even if not allocated.
+
+		Yet more mods to aclocal and various .in files from Rob Savoye.
+
+4/21/95 5.16.3	Matija Grabnar <Matija.Grabnar@ijs.xsi> noted that sleep maxed
+		out after about 36 minutes.  Turned out to be a poor assumption
+		in some interfacing code.
+
+4/19/95	5.16.2	rbd <uport@netcom.xcom> noted tcl_RcFileName multiply defined
+		when compiling with Tk4.
+
+4/16/95	5.16.1	Robert Nicholson <robert@steffi.dircon.co.xuk> noted NextStep's
+		sys/wait.h is not POSIX-like so WNOHANG fails to get a defn.
+
+		Alexandre Rafalovitch <arafalov@socs.uts.edu.xau> discovered
+		example on dislocate man page didn't work.  I fixed it.
+
+4/8/95	5.16.0	gcc 2.3.3 complains about internal errors so I figure: time to
+		upgrade.  Switched to Cygnus 2.6-95q1.  Works now but now
+		complains about wait status.  I trashed all the gory wait
+		status configure code and adopted autoconf's suggestion about
+		refusing to use sys/wait.h if not POSIX.1 compatible.  Nice!
+
+		Jeffrey C Honig <jch@nr-tech.cit.cornell.xedu> requested a -gmt
+		flag for timestamp command.
+
+		Chuck Ocheret <chuck@gigadactyl.xcom> noted that expect -pty
+		fails.  Problem is that Tcl's exec blindly closes all the fds
+		between 3 and its own highest fd.  See comments in code.
+
+		Loris Caren <loris@caren.demon.co.xuk> noted eof in fg bombs on
+		Linux.  Turns out to be analogous to eof in bg problem fixed
+		in 5.14.0.
+
+		Upgraded to autoconf 2.3.  Continued making changed to config
+		script to take advantage of autoconf 2 capabilities.
+
+4/1/95  5.15.4	Steve Simmons noted .x remnant from earlier dir install proc.
+
+3/31/95 5.15.3	Forgot to export TCLHDIR defn when configuring debugger.
+
+3/29/95 5.15.2	Steve Simmons <scs@aisinc.xcom> noted Makefile multiple defined
+		distclean and it might be nice to provide aclocal.m4 even
+		though it isn't normally used.
+
+		cevans@resdev1.ppco.com added prompts to passmass for AIX.
+
+3/27/95	5.15.1	Fixed tkterm script - inadvertently left tic debugging on.
+		Also add support for Ctrl-space and Ctrl-@ as requested by
+		Zbigniew Wieckowski <wieckows@cs.umn.xedu>.
+
+		Larry Virden asked that configure also check for .so libs.
+
+3/23/95	5.15.0	Everitt Beers <ebeers@scf.usc.xedu> noted that Linux doesn't
+		support kill -STOP 0.  Changed 0 to pid.
+
+		zhengping (z.) you <you@bnr.xca> found bug where a bg expect
+		did not rearm a spawn id after a first bg expect (and another
+		one) to clear it.
+
+		Elliott Wolin <wolin@physics.wm.xedu> noted that tkterm
+		complained if tic wasn't found.  I'll have it override the
+		user misconfig in that case.  Also noted that interact failed
+		on AIX.  Evidentally, my new config tests for ISC found that
+		AIX looked just like it.  Added additional test for tcsetattr
+		to distinguish them.
+
+		Rob Savoye asked for Dbg config.in to be distributed.  Rob
+		supplied numerous other mods: install-sh replaced install.sh,
+		mkinstalldirs, testsuite mods, new aclocal.m4, support for
+		recursive make.
+
+		Fixed bugs in configuration of debugger.
+
+		Disabled configure's file-caching.
+
+		Kannan Varadhan <kannan@isi.xedu> noted incorrect diag
+		reporting TCLHDIR in configure.
+
+		Marty Olevitch <marty@howdy.wustl.xedu> noted that DEC Alpha
+		did not sleep correctly because configure didn't find sleep
+		and found poll (which is broken).  Problem turned out to be a
+		bug in autoconf's AC_CHECK_FUNC.  Got patch from Jim Meyering
+		<meyering@comco.xcom>
+
+		Fixed config probs for Edward Huie <huie@net.xcom> on Mac
+		SE/30, System 7.1, Tenon Intersystems' MachTen 2.1.1-G (BSD 4.3
+		on Mach kernel) and MachTen X11R4 3.1.
+
+		Moved libraries forward in configure to allow for AC_CHECK_FUNC
+		to succeed when funcs are in other libraries.
+
+		Made configure test for Linux and unset CFLAGS=-g if so.
+
+2/25/95 5.14.3	Larry Virden noted configure was missing brackets in raw shell
+		cmds evidentally due to m4 interpretation.
+		
+2/24/95	5.14.2	Larry Virden noted configure was not correctly rewriting from
+		--(exec-)prefix.  Due to new autoconf.  Also noted glob was
+		finding tclX directory.
+
+		Hal Peterson noted that because configure now actually attempts
+		a link before using a library, the code to check for -ltk would
+		have to worry about all the other utility libraries first.
+
+2/23/95	5.14.1	Hal Peterson noted that configure.in checked incorrectly for
+		tcllib.
+
+2/22/95 5.14.0	Jamal <root@lonestar.tlug.xorg> noted Linux has tic in a
+		different place than on my system - affected tkterm script.
+
+		Xiaokun Zhu <xiaokun@stats.gla.ac.xuk> noted problem on DEC
+		Alpha OSF/1.3 evidentally due to backwards decl of index macro.
+
+		Greg McFarlane <gregm@nms.otc.com.xau> noted that large args in
+		send cmd cannot be passed blindly to exp_error.
+
+		david d `zoo' zuhn <zoo@armadillo.xcom> requested modifying
+		configure so that it did not require Tcl/Tk to be built - only
+		configured.  This means that it may not find installed
+		libraries.  Hopefully, this won't cause anyone problems but its
+		not my preference.
+
+		Fixed error which caused spurious eof when changing patterns
+		in expect_bg.
+
+		Moved to autoconf-2.1 and m4-1.4.  Rewrote a LOT of the config
+		file.  Finally got my hands on an ISC box and fixed configure
+		for that.
+
+		Tony Booker <tb@sequent.xcom> provides mods for Sequent ptx 2
+		and 4.
+
+		Jeffrey Friedl <jfriedl@nff.ncl.omron.co.xjp> provided fixes
+		for timezone handling in config and exp_strf.c.
+
+		David Schmitt <dschmitt@netcom.xcom> noted that library did
+		not detect eof on HP.  I didn't think this was necessary for
+		read() but it evidentally is.  I added the support for raw fds
+		although it is not obvious to me how to do it for FILEs.
+
+		James Carter <jimc@math.ucla.xedu> noted expect_after couldn't
+		worked in the exp_bg because I had accidentally written BEFORE
+		instead of AFTER when checking the cases.  He also found that
+		the eof body could be trashed in an exp_bg.
+
+		Ousterhout apologized for the Tcl7.4 change I noted in 5.13.1
+		and said he will undo it.
+
+		Eric Frias <efrias@vt.xedu> found library bombed after
+		timeouts.  exp_match_end was not updated - which makes sense
+		since there was no match - however the following expect call
+		assumed that exp_match_end was meaningful in order to do its
+		buffer shuffling.
+
+		Jonathan Kamens supplied new configure test for REARM_SIG after
+		noting old could fail if limit prevented creation of core file.
+		He also noted REARM_SIG had accidentally been commented out
+		of cf file.
+
+		Vincent D. Skahan <vds7789@aw101.iasl.ca.boeing.xcom> noted
+		that Apollo's stty reads stdout and doesn't complain if its
+		bogus.
+
+		Yoad Grinberg <grinberg@vnet.ibm.xcom> noted that SIGCHLD does
+		not work for forked processes, only spawned processes.  Fixed
+		this and added counting to make sure none get lost.
+
+		Hal Peterson contributed mods for Unicos.  He noted that
+		configure should be more careful adding libs to the link line.
+		On the Cray, non-existent libs generate warnings which are not
+		detected by configure but which annoy make.
+
+		Bela Gazdy <bela@euch3e.chem.emory.xedu> noted /etc/resolv.conf
+		misspelled in kibitz.
+
+		Rainer Wilcke noted that "send -null/break" mishandled return
+		code, and these and send/expect_tty were not in man page.
+
+		Dvorak example was missing -- in send -.
+
+1/12/95 5.13.2	Peter Wassenaar <peterw@stack.urc.tue.xnl> noted that kibitz
+		didn't work on AIX.  My fixcat script assumed that AIX's cat
+		was like HP's cat - buffered by default.
+
+1/7/95	5.13.1	Marc Bouron <mbouron@lhr-sys.bru-ro.DHL.XCOM> noted I forgot to
+		add virterm to distribution.
+
+		Marc W. Mengel <mengel@dcdmwm.fnal.xgov> noted that configure
+		must be run in the foreground due to the stty tests.  Added
+		this to documentation.
+
+		Modified interpreter to account for the change in Tcl7.4 which
+		forces Tcl_RecordAndEval to call Tcl_GlobalEval instead of
+		Tcl_Eval.
+
+		Changed ptys to be initialized based on current tty setting
+		rather than original tty setting.
+
+		Stephen Melvin <melvin@zytek.xfr> noted that set -e is the real
+		problem with ash (see 5.13).  I bet "" is returning a value
+		and triggering it.  It appears that the script can live without
+		the set, so out it goes.
+
+		Braun Brelin <bbrelin@netcom.xcom> noted pipe allocs in spawn
+		could fail with meaningless error message.
+
+12/15/94 5.13.0 Synchronize with appearance of "Exploring Expect".  This
+		distribution corresponds to the book both in description of
+		Expect and in containing all the substantive examples.
+
+		Graham Mark <gam@lanl.xgov> noted that his Cray (Unicos
+		7.0.6.1) didn't recognize TCSETCTTY.  Since this was in some
+		Cray-specific code, I guess Unicos must have changed some .h
+		files.  I made it include either termios or termio.  It, at
+		least, works on our Cray (Unicos 8.0.2.4).
+
+		Robert Withrow <witr@rwwa.xcom> noted that FreeBSD 1.1.5.1
+		supplied union wait but waitpid doesn't use it!  So I modified
+		configure to be smarter.  He also noted that its /bin/sh is
+		really ash which blows up on install.sh.  It appears that it
+		doesn't handle uninitialized parameters correctly.  I'm not
+		going to fix this because having a broken /bin/sh is so awful
+		probably other things are breaking too.  He did note that it
+		worked if he switched to bash or the native install, but that
+		blows the whole point of install.sh - that we have found too
+		much variation in native installs.  Rather than try and figure
+		out everyone's variation, we'd like to simplify our life and
+		use this common, simple-to-understand sh script.
+
+		Added more example scripts: Adrian Mariano's virterm (like
+		expect_term but without relying on Tk), gethostbyaddr, and
+		expectd.proto for telnet daemon.
+
+		Matt DiMeo <mdimeo@brooktree.xcom> noted that expect_background
+		failed to detect eof on HP.  I had forgotten to pass the mask.
+
+		Josef Sachs noted that expect_background put Tk's event	handler
+		in an infinite loop if it was listening to a pipeline that was
+		killed.  I had aborted the cleanup procedure if Tcl's close
+		reported an error.  That was a mistake.
+
+		Rick Lyons <rick@razorback.brisnet.org.xau> noted a bug.  C lib
+		expect would turn a normal read into a poll if remtime reached
+		zero on the nose.
+
+		Added ResetResult to Exp_Init to clean up diags in Expectk.
+		Made GENFUNCs return -1 on error as per ParseArgv's convention.
+
+11/13/94 5.12.0	Alon Albert noted that in clib, exp_match_end should be init'd
+		to exp_buffer before trying to match the pattern - if the
+		expect doesn't produce a match, exp_match_end is incorrect and
+		will be wrong for subsequent expects.
+
+		Steven Diamond noted that fg expect did not react to a change
+		in an indirect spawn id list if it was just waiting for I/O
+		(rather than looping in exp_continue).
+
+		Wait fix in previous version broke system() whose return value
+		is horribly overloaded.
+
+11/10/94 5.11.0	Stephen Fitzpatrick <sfitzp@cs.qub.ac.xuk> noted that NeXT wait
+		macros do not accept int wait status.  Switched to using Tcl's
+		detection of wait status type.
+
+		Made log_file -leaveopen leave file id open until close like
+		spawn -leaveopen did.
+
+		Bruce Jerrick <bruce@cse.ogi.xedu> noted public include dir
+		wasn't getting created.
+
+		Karl Vogel noted 1) Pyramid has index instead of strchr, strf.c
+		needs sys/time.h instead of time.h in strf.c, needs to call
+		timezone(), and stty reads stdout but usual stty test fails.
+
+		Made expect_out(spawn_id) always be written to assist people
+		who want to log different procs to different files.  This is
+		no longer an efficiency problem because interact can do so
+		much more then it used to.  Made full_buffer condition write
+		forgotten chars even when full_buffer isn't explicitly
+		specified.
+
+		Bert Robben <Bert.Robben@CS.kuleuven.ac.xbe> noted that the
+		debugger needs to know about the presence of stdlib.h.  I was
+		hoping to avoid this because it's a pain getting configure to
+		call another configure.
+
+		Rainer Wilcke provide several improvements for xkibitz and man
+		page.
+
+10/6/94	5.10.0	Moved example files around.  Added password generation to
+		tkpasswd.  Created standalone script to generate and set
+		passwords - good for all those adduser shell scripts.
+
+		Rick Cady <rickc@NSD.3Com.XCOM> found a bug when switching log
+		files.
+
+		Rainer Wilcke <wilcke@esrf.xfr> noted that xkibitz died when
+		closing a connection.  stdin was mistakenly being closed.  He
+		also noted that killing xterms under HPUX 9 requires kill -9.
+
+		Enzo Michelangeli <enzo@airhk.air.xorg> noted that SCO 3.2.1
+		defined window size structure in ptem.h.
+
+		Josef Sachs <sachs@panix.xcom> found a bug when calling fg
+		expects repeatedly between bg expects.  On the first fg	expect,
+		it cached the fact that the filehandler was armed.  The next
+		background expect disarmed it but failed to update the cache.
+
+		John P. Rouillard" <rouilj@dstar.iddis.xcom> provided configure
+		support for --with-{tcl,tk}{lib,include}.
+
+		Mike Figg <figg@pencom.xcom> noted that man page used old style
+		of continue command.
+
+8/23/94	5.9.1	Adrian Mariano noted it would be useful to have exp_continue
+		not reset the timer.  Added flag to support this.
+
+		Morris Gasser <gasser@ksr.xcom> noted that lowering match_max
+		didn't work (lib was broken too).
+
+		Keith Hanlan provided a fix for exp_exact.
+
+		Added more examples: mkpasswd, tkterm, term_expect.
+
+		Put close_tcl_files in sep file for easier non-Tcl use of clib.
+
+8/21/94	5.9.0	Fixed window handling code - on AIX, termios does not define
+		TIOCGWINSZ.  Instead, you have to include ioctl.h.  Of course,
+		you have to avoid the trap of including both on OTHER systems
+		such as SunOS 4.1 where the include files conflict!
+
+		Dan MacDonald found that close in async routine caused sync
+		expect to blow up.
+
+		Missed deletion of last line of out macro in exp_inter.c
+
+		Simon Warfield <simonw@bwh.harvard.xedu> noted bug in xkibitz
+		help message.
+
+		Fixed exp_background to use global scope instead of current.
+
+		Steve Diamond <sdd@aplcomm.jhuapl.xedu> noted that -i "4 5"
+		only used spawn id 5.
+
+		Rob Nagler found yet another bug in log_file when called
+		incorrectly.
+
+		Expectk wasn't creating a window by default.
+
+7/25/94 5.8.1	Made exp_interp external.   Users should be able to set this
+		explicitly.
+
+		David Barnett <davidb@cats.ucsc.xedu> found that Linux was not
+		getting a controlling terminal.  The original test for doing
+		that was based on Stevens and tested in a very nonspecific way
+		for the presence of a Sun via CIBAUD.  Replaced this with a
+		more specific test.
+
+		It seems Tcl 7.3 broke my -nostack hack.  The top-level interp
+		translates unknown return codes to TCL_ERROR.  Sigh.  I wish
+		Ousterhout would stop all of those translations.  If the user
+		wants them, they can do so themselves, but now they're forced.
+
+		Martin Buchhoz <buchhlz@vnet.ibm.xcom> suggested adding
+		XKIBITZ_XTERM_ARGS environment variable to xkibitz.  He also
+		noted that stty rows/columns support doesn't seem to work on
+		AIX.  I haven't yet looked into this.
+
+		Copied 2nd sync mechanism from Expect to C library.
+		Added exp_child_exec_prelude hook.
+
+		Jonathan Kamens noted that "spawn cat;close;wait" returned
+		-1 on AIX and 0 on Sun.  This is "correct", however to
+		address this, I added -ignore to spawn and otherwise made
+		signals default.  Also added extra information to return value
+		of wait if caused by signal.
+
+		Dan MacDonald <hfvstud@bcarh80a.bnr.xca> noted that
+		exp_continue didn't cause timeout to get reread.
+
+		Ting Tan <utan@cisco.xcom> noted that when using -b, expect
+		hangs if open brace and doesn't stop in case of error.
+
+		Oops, broke "log_file" with no args.
+
+		Removed -timestamp from documentation.  Use "timestamp" command
+		instead.
+
+		Keith Hanlan noted C library didn't test already arrived data
+		before attempting to read more.  He also suggested I avoid
+		forcing the user to do save/restores of per-fd globals.
+
+6/24/94 5.8.0	Hubert Halkin <hhalkin@ucsd.xedu> pointed out that interleaved
+		expect_bgs and spawns dump core.  I had used the exp_f ptrs
+		as handles to TkCreateFileHandler but realloc shuffled them
+		around.
+
+		Rick Lyons <pclink@qus102.qld.tne.oz.xau> provided misc. mods
+		for Pyramid.
+
+		Keith Hanlan <keithh@bnr.xca> noted that HP-UX C compiler
+		causes odd behavior in Expect when it is compiled with "-O.
+		-g" works fine.
+
+		Peter Gasche <zrspg01@compserv.zdv.uni-tuebingen.xde> pointed
+		out that Convex 10.2 fails to build.  New version of Convex OS
+		added getpty().  Naturally, it differs from old one.  Testing
+		is tricky because there is no header file for it.  Even worse,
+		the algorithm in the Convex man page is incorrect - it allows
+		you to allocate ptys already in use!  Unfortunately, the man
+		page is too vague to allow the reader to see that immediately.
+
+		In contrast to BSD stty, Convex, Mach, and NeXT stty don't
+		complain if redirected to null.  I'll just have to hardwire the
+		test in configure.
+
+		Added -nowait flag to wait command.
+
+		Upon suggestions from David Vezie <dv@xnet.ssl.berkeley.xedu>:
+		Added -noappend, -open, and -leaveopen to log_file command.
+		Added -leaveopen flag to spawn and exp_open.
+		Modified spawn to close -open immediately.
+		Modified exp_open to close spawn_id immediately.
+
+		Between Jeff Wright <wright@spock.cen.encompass.xcom>, Brad
+		Skrbec, Arup Mukherjee <arup+@cmu.xedu>, and the anonymous
+		Mach support group at CMU, finally got hard answers about Mach.
+		It is no longer supported and there is no intention to provide
+		full POSIX support.  Now, at least, I can fix the configure
+		script to understand this.
+
+		Added "unbuffer" example.
+
+		Dana Chee <dana@dino.bellcore.xcom> provided configure hooks
+		for finding -lnsl and -lsocket.
+
+		Henry Spencer <henry@zoo.toronto.xedu> noted timestamp doc did
+		not jive with C defn.  Fixed doc and added timezone support.
+
+		Steve Pynes <fb@steve@ucsd.xedu> noted that exp_win.c needs
+		_IBCS2 (Intel Binary Compat Standard #2!?!) before it will
+		recognize winsize.  He also noted #out was redefined in inter
+		code if using simple_event.
+
+		Fixed defn of "stty cooked" to retain echo setting.
+
+		Bennett Todd noted dislocate's pidfile_read was missing close.
+		He also noted useless bind in tkpasswd.
+
+		Marty Leisner noted that ^C causes xkibitz to exit ungracefully
+		when in interpreter.
+
+		Added yet another sync mechanism (see 5.6) to spawn so that
+		child cannot eof before parent has prepped the pty (only a
+		probably on HPs, of course).  I had actually written most of
+		the code, but left it disabled because I hoped that the
+		problem simply wouldn't happen in practice.  Alas, Jonathon
+		Kamens found a case where it does.
+
+		Jimmy Aitken <jimmy@pyra.co.xuk> noted problem on Pyramid.  My
+		original code only looked for /dev/tty##.  On pyramid, ptys
+		look like /dev/pts/4.  term wants the last two characters, but
+		on the Pyramid, the first of the last two characters can be a
+		/ in which case xterm wants a 0.  I.e., suffix of /dev/pts/4
+		is "04".  xterm fails completely with 3-digit ptys!  I sent
+		a suggestion and patch to X Consortium for this and the pid
+		problem - xterm has no way of telling it to which pid to send
+		the SIGWINCH.
+
+		Poul-Henning Kamp <phk@TFS.XCOM> noted that -lm would make
+		autoconf forget about other libs.
+
+		Ram Bhamidipaty noted I forgot to document sleep.
+
+		Removed disasterous performance with * at beginning of glob.
+
+		Mods from Rob Savoye.  See ChangeLog.
+
+		Earnest Hua <eh@c-cube.xcom> noted expectk.man need wasn't
+		installed.
+
+		Bogus arguments to expectk were not reported correctly.
+
+		Modified clib to catch when user changes match_max between
+		expects on two different fds and then switches back.
+
+		Rewrote timestamp to get rid of 200 char limit.
+
+		Ram Bhamidipaty <ram@xor.epi.wisc.xedu> noted NetBSD .9 stty
+		complained "stdout appears redirected, but stdin is the
+		control descriptor".  It compares dev(stdout) to dev(stderr)
+		and assumes if they are different then user thinks stty
+		ioctls stdout.  This is one case when that assumption is wrong.
+		Fixed fd 2 so it points new 2 and is reset to old 2 if an
+		error occurs.  This forced me to remove any diagnostic output
+		from child (in getptyslave) since this now went back to the
+		proc as child output rather than original stderr, sigh.
+
+		Stephan Winokur <swinokur@pinky.trevose.sgi.xcom> noted that
+		IRIX 4.2 had problems with gcc.  While diagnosing, I found
+		PTY_TYPE was used before set.  Make doesn't mind (how odd)
+		but I changed it anyway.
+
+		Made send understand "-null".  Deprecated "-0".
+
+		Made Expect read .expect.rc from DOTDIR if present.
+
+3/30/94	5.7.0	Removed alpha status.
+
+		Added $(EVENT).o to library.
+
+		Finally deleted old shar file.  Revised README.
+
+3/22/94 5.6.3	Phil Moore <phil@signals.geol.scarolina.xedu> noted termios.h
+		should not come from sys even if it exists.  (SGI doesn't have
+		sys/termios.h.)
+
+3/21/94 5.6.2	Paul Kinzelman <pkinz@cougar.tandem.xcom> noted that I forgot
+		to remove -update from documentation.
+
+		Fixed interact's -i so it understands indirect spawn ids.
+
+3/21/94 5.6.1	expect_background randomly failed.  I forgot to save Tk's
+		event mask so occasionally events were incorrectly classified
+		as eof.
+
+		Added -buffer to expectk and made "nobuffer" the default so
+		scripts are read in much faster.
+
+3/15/94	5.6.0	Added cat_buffers marker to avoid "catu" option to scripts.
+
+		Got temporary use of an evaluation copy of TestCenter.
+		Promptly found several memory leaks.  Oops.
+
+		Added a synchronization mechanism to spawn so that user cannot
+		send to pty before it is init'd.  This also deals with the HP
+		trap more simply.  Removed extra open added in 5.5.1.  While
+		working on this, it occurred to me stty needs to temporarily
+		disable trap.  Added exp_slave_control so that C programmers
+		can get to it portably.
+
+		Added "expect -ex" to documentation.
+
+		Fixed winsize bug on Solaris.
+
+		Added functions to allow user flexibility closing fds in child.
+
+3/8/93	5.5.1	Integrated bug fixes from Arnold Robbins <arnold@skeeve.atl.
+		ga.xus> for his own strftime code.
+
+		Rob Savoye passed back a patch from OSF to cast ptsname.
+
+		Added a test for cat.  R.K.Lloyd noted HP failed pid test.
+		Turned out to be another bug related to pty-trapping.  The test
+		of course, was doing something that a user would never do.
+		Hope this doesn't break other HPs.   Pty trapping is becoming
+		less and less clear to me.  Ioctls generated by slave look like
+		modem ioctls.  Added an artificial open because different
+		versions of HP's stty execute differing numbers of ioctls.
+		In test script, changed each cat to cat -u.
+
+2/17/93	5.5.0	Began a test suite based on Ousterhout's model: make test
+
+		Added passmass man page.
+		Added decl of exp_tty_original to pty_sgtty.c.
+		Added error_spawn_id
+
+		Alon Albert <al@mercury.co.xil> provided a bug fix for new
+		buffer handling code in C library.
+
+		Fix fd leak related to spawn -open.
+
+2/7/94	5.4.0	Some installation improvements from Rob Savoye and Owen Rees.
+
+		Bug in handling empty string match - crept in recently.
+
+		Finally fixed longstanding oddness: stty -raw reset echo.
+
+		Made spawn close all file descriptors.  Added exp_open command
+		to get old effect.
+
+1/26/94	5.3.5	Made rftp use /bin/ls to avoid -F from people's aliases.
+
+		Initialized auto_path.
+
+		Fixed exp_version so it fails if the major #s are not equal
+		(which is what the man page said).
+
+1/18/94 5.3.4	Jim Meyering <meyering@idefix.comco.xcom> gave config fixes
+		of X handling on Irix-4.0.5 and suggested that tknewsbiff
+		observe DOTDIR.
+
+1/18/94	5.3.3	Kevin Short <short@gdc.xcom> noted some remaining use of malloc
+		and free instead of ck versions.
+
+		Initialize tcl_interactive to 0 while processing -c flag to
+		avoid unreliable handling of unknown proc.
+
+1/17/94	5.3.2	Jeffry Abramson <jra@hrcms.att.xcom> noted that "spawn -pty"
+		hung on an HP.  Problem was trapping was enabled so as soon
+		as I tried to open the slave, Expect blocked waiting for ack!
+
+1/14/94	5.3.1	Forgot to delete a bad call to strcat in exp_internal.
+
+1/13/94	5.3.0	Added -info flag to log_file, log_user, exp_internal, and
+		strace, so you could get original args back out.	
+
+		Wrote tknewsbiff script (and was extremely pleased).
+
+		Fixed rftp.  I must have broke it when I changed to using Tcl's
+		new switch cmd.  Also sped it up by replacing split/join
+		nonsense with a single regexp.
+
+		Danny Faught <faught@convex.xcom> noted that glob patterns
+		returned shortest matches.  While fixing this, found that glob
+		patterns ending in $ were broken, too.
+
+		Massaged libraries and include files.  The include file for
+		using Expect with Tcl or Tk is now expectcl.h.  libexpect.a
+		now suffices for using Expect's funcs with C or Tcl.
+
+		Add all the features from Expect into C library including
+		null and full buffer matching.  Added exp_buffer (_end) and
+		some other variables to support fd multiplexing better.
+		Made unmatched chars from previous expects remain for future
+		matches.
+
+		Chen <johnny@e0sun3.ccl.itri.org.xtw> found bug in exp_pid when
+		-i had no arg.
+
+		Rewrote expect_bg, after, and before so they all handle args
+		the same.  Interact and all the expect variables now handle
+		indirects.  exp_bg now handles -brace flag.
+
+		Geoff Bullen <geoff@itx.nsg.com.xau> noted that interact put
+		terminal into raw mode even if stdin was redirected.
+
+		Rob Savoye provided more configure mods to better find Tcl/Tk.
+
+		Fixed bug in wait that didn't close down "busied" fds.
+
+		Kazuro Furukawa <furukawa@apricot.kek.xjp> provided a better
+		default for SHORT_BINDIR in the Makefile and noted that DEC
+		doesn't understand "test -x".
+
+12/3/93	5.2.0	Recent fix was buggy and blew up when eof case still had data
+		in buffer.
+
+11/23/93 5.1.4	At request of Rod Beckwith <rodb@slugo.corp.sgi.xcom> fix some
+		minor things to which SGI cc was sensitive.
+
+		Fixed bug in dvorak script where eof could occur in nested
+		interact, upsetting original interact.
+
+		Forgot to change -flush to -nobuffer in man page.
+
+		Added some more places to search for X11 for Jeff Moore
+		<jbm@internet.sbi.xcom> note.
+
+		Added yet more fixes and notes for NeXT for Brad Skrbec
+		<skrbec@motcid.rtsg.mot.xcom> who found that NeXT has POSIX
+		include files but NOT the functions that go with them.  Sigh.
+		Needless to say, configure is thrown off by this.
+
+11/14/93 5.1.3	John Pierce <jpierce@chem.UCSD.XEDU> noted several declarations
+		that AIX's cc couldn't handle include a struct with same elt
+		name at two different levels.  Also _IO is declared twice
+		in AIX include files but only checked once.
+
+		Fixed bad args in exp_spawnl call in chesslib examples.  Can't
+		imagine how it ever worked before.
+
+		Richard Weidner <richard@cicero.jpl.nasa.xgov> found a bug in
+		configure (test always treats a bare string as true!) that
+		caused NeXT to be declared as POSIX.
+
+		Fixed two bugs in Tcl_StringMatch2.  One caused glob ranges to
+		succeed when they shouldn't.  Another was how malformed ranges
+		are handled, and came right from Tcl.  Reported to John.
+		Switched Expect library to use T_SM2 from Expect itself.
+
+		Blair Zajac <blair@olympia.gps.caltech.xedu> noted expectk used
+		CLFLAGS instead of CFLAGS.
+
+		Forgot to fix mishandling of parens inside of alternation in
+		interact.
+
+11/9/93	5.1.2	Added "null" keyword and remove_nulls command to allow matching
+		ASCII 0 in expect/interact.
+
+		Rob Nagler <nagler@olsen.xch> noted that expect_background
+		failed if pattern didn't consume all data.  event handler
+		knows nothing about data already arrived but not processed.
+
+		Made Expectk understand --
+
+11/8/93	5.1.1	Fixed yet another bug in setting expectk's argv0.
+
+11/6/93	5.1.0	Provided support to work with Tcl 7.0-1 and Tk 3.3-4.
+
+		Pasi Kaara <ppk@atk.tpo.xfi> found an off-by-one in the buffer
+		shuffling when buffers fill up during an expect.
+
+		Changed \\\$ to \\$ in patterns that search for literal $.
+
+		Added "spawn -pty" support for xterm -S.
+
+		Fixed yet another argv problem in Expectk.  When run using
+		expectk explicitly, script name was left in argv.
+
+		Fixed system command's return value to match exec new style.
+
+11/1/93	5.0.4	Mark Davies <mark@comp.vuw.ac.nz> noted that BSD4.4 sysconf
+		returns -1 (a bug).  Rewrote to avoid requiring this info.
+		Switched from from explicit refs of sys_errlist to Tcl's
+		strerror.
+
+		As per Adrian Mariano <adrian@cam.cornell.xedu>, added
+		exp_sleep command primarily to allow sleeping by sub-second
+		intervals.  Also avoids exec overhead.  Not yet documented.
+
+		Kartik Subbarao <subbarao@concorde.fc.hp.xcom> noted that on
+		HPUX 9, SC_OPEN_MAX should be ifdef'd on itself rather than
+		HAVE_SYSCONF.
+
+		Karl Vogel <vogelke@c-17igp.wpafb.af.xmil> noted Pyramid
+		didn't like varargs included twice in exp_command.c.
+
+		Deleted expect_version variable (was never documented) and
+		deprecated expect_library to be exp_library for consistency.
+
+10/16/93 5.0.3	Lou-Salkind@deshaw.com found interpreter() could stomp past end
+		of input array.  Same problem in debugger.
+
+		Bud Bach noted init.tcl wasn't being sourced, and Makefile
+		broke if all scripts were commented out.
+
+		Added interesting highlights and bindings to tkpasswd.
+
+		Made Makefile look for -ltk if libtk.a doesn't exist.
+
+		Rick Sladkey pointed out that -re patterns to look for $ should
+		"\\\$".
+
+		R.K.Lloyd noted config doesn't see prototypes with K&R cpp.
+
+10/8/93 5.0.2	Bud Bach noted tcl_interactive was not set.
+
+10/8/93	5.0.1	R.K.Lloyd noted various problems, some related to being on an
+		HP when a lot of #ifdefs kicked in.
+
+10/7/93	5.0.0	Added expect_background.  In the Tk environment, this registers
+		actions to be called upon receipt of a pattern from a process.
+
+		Renamed "debug" as exp_internal" and made debugger available
+		as "debug" and "exp_debug".
+
+		Milan Gupta <mbg0@bunny.gte.xcom> noted that system() (at least
+		on his HP) hangs when SIGCLD is ignored.
+
+		<jason@vicor.xcom> noted that Tcl's exec command doesn't bother
+		to close fds, so force them with close on exec.
+
+		Renamed "continue -expect" as "exp_continue".  "continue
+		-expect" will continue to work, just won't be documented.  It's
+		just too dangerous when you start mixing extensions.
+		Renamed "return -tcl" as "inter_return".  Had to do something
+		to avoid random return values from matching "-tcl".  This
+		design was just wrong.  Surprising that it never bit anyone.
+		Renamed "expect_version" as "exp_version" just to continue
+		this regularity.
+
+		Protected initial fd_new's with isatty so disconnect doesn't
+		lose redirected fds.
+
+		Allowed DFLT_STTY to be omitted entirely.  Apollo doesn't need
+		it.
+
+		Modified fork to fail on failure instead of returning -1.  This
+		made spawn failure match disconnect failure.
+
+		Dan Hyde <drh@citi.umich.xedu> noted missing arg in exp_error.
+
+		Jerry Whelan <guru@stasi.bradley.xedu> noted -buffer was
+		botched in man page.  Hal Peterson noted that bug in man page
+		caused groff to choke.
+
+		wait now returns {pid, spawn_id, 0|-1, status (or error msg).
+		errorCode is now set if appropriate.  wait -i -1 waits for any.
+
+		Propagated winsize to pty.
+
+		Documented "-open".
+
+		Quentin Stafford-Fraser <Fraser@europarc.xerox.xcom> noted that
+		interact -u was broken.
+
+		Fixed interact's default actions "return"/"interpreter" to be
+		writable.  Removed ability to set default eof/timeout.  Removed
+		dash from same.
+
+		Rewrote trap to use Tcl's async support.  
+		Added -code switch and made interpreter understand "-nostack"
+		coming from error to use ^C to easily return to interpreter.
+		Introduced following incompatibilities:
+		- ONEXIT interface disappeared.  Use "exit -onexit".  (Thinking
+			of this as a signal bought nothing but complexity.)
+			Added "exit -noexit" to run all expect-related exit
+			handlers without exiting or destroying interp or ".".
+			Useful for when other apps have exit handlers.
+		- trap command takes missing action as a query.	 Use "" or
+			SIG_DFL to delete or reset a trap.
+		- SIGCLD gone.  Now always called CHLD even if underlying
+			system only knows about CLD.
+		All sig handlers and exit handlers run at global level.
+
+		Removed setjmp/longjmp crap.  Not needed since systems which
+		wait in read don't restart system calls.
+
+		Added support in expect for "-gl" and allowed longer forms to
+		match Tcl's switch command.  Similarly for "-ex" in interact.
+		Rewrote arg parsing for send.
+
+		Added "stty" command to support stty of ttys other than
+		/dev/tty.  Better for /dev/tty, too.  This should fix
+		security complaint from BSD's Net2 stty.
+
+		<R.K.Lloyd@csc.liv.ac.xuk> gave fixes for configure and noted
+		exp_main_tk was missing exp_conf.h.
+
+		Added "exp_timestamp" command.  Fixed bug in interpreter cmd.
+		It wouldn't return anything with TCL_OK.
+
+		Renamed -flush to -nobuffer.
+
+		Make interact default to executing actions in raw mode.
+		Accept -reset to execute in cooked mode.  Ignore -f.  
+		Fixed examples.  Fixed bug in "-o -timeout".
+
+		Deprecated getpid (due to Tcl's pid), added exp_pid.
+
+		Put "rm -f" inside catch.  SunOS 4.1.3 and some version of AIX
+		complain despite the -f!
+
+		Added "send -break" for Dave Mielke.
+
+		Fixed argv handling of expectk to match expect for Steve Clark.
+
+		Switching to Tcl 7.0
+
+8/21/93 4.7.7	Cygnus added support for OSF/1 style ptys.
+
+		Brian Bebeau <brian@cblph.att.xcom> found bug in PTC support,
+		HAVE__GETPTY, timestamp doc, and provides some mods for config
+		AT&T StarServer.
+
+		Detection of direct spawn ids failed on -1.
+
+8/18/93	4.7.6	Removed zone and gmtoff from timestamp.  Not ANSI.
+		Removed getpid confusion.
+		Once again, added "cat -u" into kibitz (this time for AIX 3.2).
+
+8/18/93 4.7.5	De Clarke <de@lick.UCSC.XEDU> hit error in exp_global.h because
+		tcl.h had not been included.
+
+8/16/93 4.7.4	Richard Kasperowski <richk@icad.XCOM> found that Ultrix 4.1-2
+		failed to allocate controlling terminal.  Ultrix's setsid is
+		evidentally buggy.  Switched back to setpgrp - which fixed it.
+
+		Fixed type defn of exp_tty_original.
+
+		Dave Mielke found two bugs in interact: re-failure prevented
+		other patterns from matching a particular point in the stream,
+		and two or more -inputs didn't actually work.  Also found bug
+		in HP trap handling - despite what docs say, other things
+		besides open/close have to be handled.  Specifically, slave was
+		generating an ARGGET.  Backed off on trying to wait immediately
+		for two OPENs to just waiting for one OPEN.  Perhaps zero?
+		Also found deficiency in return -tcl - failed to return arg.
+
+		At Dave's request, made cmdfile by read in a single gulp rather
+		than line by line.  Added -b (buffer) flag for old behavior.
+		Old behavior performs badly on very long procedures but is use-
+		ful for reading commands from pipes.  Made "system stty" return
+		status of raw/echo.
+
+		Made log_user return previous value irrespective of args.
+
+		Fixed mishandling of parens inside of alternation noted by
+		Bud Bach <bachww@rtsg.mot.xcom>.
+
+		Added -timestamp, -iread, and -iwrite to interact and
+		expect.
+
+		Added -onexec flag to close to solve problem posed by
+		Bellave Jayaram <bjayaram@slee01.srl.ford.xcom>.
+
+		Added -0 to send.  Removed capability of send to send multiple
+		strings.
+
+		Chip Rosenthal noted bug in releasing trap 0's action.  Also
+		modified exit handler to allow recursive invocation.  Instead
+		of complaining, it skips handlers that have already been
+		invoked and forces the process to exit.
+
+		Added new names for most command prefaced by "exp_".
+		Deprecated send_spawn.
+
+		Switched to Ousterhout's ckalloc and attitudes towards failure.
+
+		Started adding Tcl 7.0 support.  getpid renamed to pid.  Added
+		exp_pid to support things that Tcl 7 does with its pid.
+
+6/12/93	4.7.3	fnf@fishpond.cygnus.com noted minor type problems.  Rob Savoye
+		noted trap SIGINT overrode debugger handler.  Default should
+		be reverse.
+
+6/8/93	4.7.2	Added debugger to public release.
+
+6/7/93	4.7.1	Ed Oskiewicz <eo@ansa.co.xuk> noted prototype botch - exp_cook.
+		Owen Rees <rtor@ansa.co.xuk> noted missing decl for
+		tclRegexpError.
+
+6/6/93	4.7.0	Gert Bultman <bultman@dgw.rws.xnl> exposed a bug in interact's
+		-update.
+
+5/27/93	4.6.0	Rick Sladkey <jrs@world.std.xcom> fixed a bug in send_log -
+		checking a master needlessly and indexing off the end of an
+		array.
+
+		Rob Savoye made change for detecting libpt.a, modified
+		autoconf for better handling of X, exec_prefix, and ranlib.
+
+		Kris Woeppel <krisw@cs.athabascau.xca> said SVR3 doesn't have
+		wait.h.
+
+		Made libexpect.a understand regexp.  Reorganized code.  It
+		now requires Tcl to be installed first, although it uses only
+		a few utility routines.  Hopefully this isn't a problem for
+		anyone.
+
+		Zack Xu <zack@cs.wisc.xedu> noted exp_main.h needed C++
+		support.
+
+		Pascal Meheut <pascal@cnam.cnam.xfr> gave fix for skipping over
+		null bytes while interact is pattern matching.
+
+		Added "--" to expect, interact, and send.
+
+		Added support for associating multiple -i's with a single
+		pattern, and -i's with no pattern for use with spawn_id_any.
+
+		Made interact work with systems that lack select/poll.
+
+		Added code and #defines for debugger.  Debugger itself is not
+		yet available.
+
+4/19/93	4.5.2	Achim Flammenkamp <achim@HRZ.Uni-Bielefeld.XDE> noted that I
+		documented full_buffer as buffer_full.
+
+		Ted Stockwell <ted@sirius.aggregate.xcom> noted that wait arg
+		was missing an & in configure test.
+
+		Scott Hess noted that systems can have wait4 without waitpid.
+
+		Jonathan Kamens <jik@gza.xcom> noted/fixed some things that
+		weren't autoconf'd correctly: pid_t, RETSIGTYPE, malloc.
+
+		Gary Shea noted that a recent change to expectk made it not
+		default to interactive.		
+
+4/12/93	4.5.1	At request of Rusty Wilson <zrlw05@hou.amoco.xcom>, added
+		"-console" to spawn.
+
+		Pang Wai Man Raymond <wmpang@cuse1.se.cuhk.hk> reported that
+		passmass didn't recognize DEC's passwd prompts for root.
+
+4/7/93	4.5.0	Fixed bug in interact regexp preventing match of multichar
+		literals.
+
+4/6/93	4.4.3	Bennett Todd <bet@sbi.xcom> noted missing example scripts
+		timed-read and time-run.
+
+3/29/93	4.4.2	Bill Houle <Bill.House@SanDiego.NCR.COM reported fixes
+		for SVR4 pty support to compile.		
+
+		Made string matcher understand *$.  Documented tty_spawn_id.
+		Made command line -i override -f.
+
+		For Tuan Doan <tdoan@bnr.xca> on HP, make kibitz use domainname
+		as fallback and used whoami instead of env(USER).
+
+		Fixed bug in the generic pty code that could report out of ptys
+		because an earlier slave slowly deleted the lock file.
+
+3/25/93 4.4.1	Stephen House <sdhouse@bnr.xca> reported exp_tk.c wouldn't
+		compile on HP.  Fixed.
+
+3/24/93	4.4.0	Added back SVR4-style pty allocation which got omitted in the
+		autoconfig process.  Fixed bug in interact's -update handling.
+		Fixed bug in weather script that cut off long reports.
+
+3/15/93 4.3.0	Cleaned up /tmp files used during pty locking.
+
+		Added command "parity" to enable parity stripping.  Fixed
+		match_max to do -i correctly.
+
+3/15/93	4.2.4	Fixed to work on new SGI which returns slave-close via excep
+		(select) or POLLERR (poll) rather than thru read().
+
+3/12/93	4.2.3	Fixed to work on AIX (using /dev/ptc) and UTS (using getpty).
+
+3/11/93 4.2.1-2	Fixed numerous bugs relating to HP ptys.  It's amazing that for
+		their bewildering complexity, they couldn't support generation
+		of EOF to the master (or at least enable trapping of just
+		close), rather than forcing the code to know about opens, too.
+
+3/8/93	4.2.0	Integrated Rob Savoye's autoconfig code.
+
+		Interact mishandled new -eof flag.  Added -update.
+
+		Gary Shea <shea@cs.ukans.xedu> noted that tkwait hung if
+		expect had been called.  Rewrote most of tk_event.c and fixed
+		some other problems related to efficiency & multiple timeouts.
+
+		E Beck <beck@qtp.ufl.xedu> suggested mods to more easily
+		support	Extended Tcl.
+
+		Bill Mitchell <mitchell@mdd.comm.mot.xcom> reported problems on
+		4.3+BSD.  Added	support for TIOCSCTTY.
+
+		Dana Burd <dana@wrs.xcom> noted that "exit" caused by ^C during
+		expect didn't work - just returning to expect.  Fixed, and then
+		removed "feature" of ^C to abort a timeout.  This feature
+		proved a lot less useful than I thought it would.
+
+2/21/93 4.1.0	Bill Tierney <wtierney@leland.stanford.xedu> noted that double
+		close dumped core.  Rewrote fd_to_f and close/adjust functions.
+
+		Interactive interpreter() didn't properly wait in
+		get_next_event, so Tk stopped responding to events.
+		Wrote version of interpreter that shares expect's input buffers
+		but can't think of a use.  Left as an ifdef SHARE_CMD_BUFFER.
+
+1/26/93	4.0.1	Added eof check to xpstat.  Removed incorrect and unnec.
+		#includes from exp_main_exp.c
+
+		Chip Rosenthal <chip@chinacat.unicom.xcom> found my refs to
+		tclRegexpError need externs on systems that don't use Tcl's
+		string.h.  string.h should probably be changed not to refer to
+		tclInt.h.
+
+		Added FAQ about Expect's copyright status.
+
+		Mark Christopher <christo@bnr.xca> pointed out some really
+		stupid errors in the HP support for select.	
+
+12/16/92 4.0.0	Rewrote interact.  Made re-entrant thru event-handler for Tk.
+		(Same for Expect.)  Abstracted out common code so that
+		remainder is specific to select vs poll vs tk (although
+		"simple" was impossible to handle).  Added timeouts, regexps
+		(at request of numerous people), ability to set up arbitrary
+		graphs of process flows, and some miscellaneous but useful
+		functionality.  New flags are: -input, -output, -re, -echo,
+		-flush, -eof.
+
+		Added "-noecho" to spawn command.
+
+		Added getpid command.  Something with this functionality should
+		be added to the Tcl core.  When it is, this function will go
+		away.
+
+		Removed assumption of global "interp" handle.  Rewrote init
+		and other routines for use as libraries.  Added appropriate
+		glue to Makefile.
+
+		At request of Rob Savoye <rob@cygnus.xcom> added "send_log" and
+		disabled buffering on all output.  The only affect unbuffered
+		output will cause users is if they pass large strings in
+		multiple args to send.
+
+		Ray Davis <rdavis@masschaos.de.convex.xcom> reported Convex 
+		could not do job control from spawned procs.  I added a symbol
+		DO_SETSID to force this.
+
+		Martin Leisner modified rftp to understand iftp.  I added it
+		to the publicly donated scripts directory.
+
+11/17/92 3.24.1	Martin Leisner suggested Makefile use $(MAKE) and support Tcl
+		as a Sun shared library.
+
+		Seth Perlman <seth@welchgate.welch.jhu.xedu> suggested interact
+		support timeout.  I've added this as "-timeout" in inter_select
+		but left undocumented while we experiment with interface.
+
+		Joe VanAndel <vanandel@ncar.ucar.xedu> pointed out that su2
+		script still used old syntax.  Fixed.
+
+		Konrad Haedener <haedener@iacrs1.unibe.xch> fixed a bug in
+		POSIX tty handling on AIX.  Surprisingly, we discovered AIX
+		worked just fine when pty_bsd is used and without -DPOSIX!
+
+		Doug (George Jetson) <pynq@midway.uchicago.xedu> pointed out
+		that a spawn_id for /dev/tty would be really handy.  I added
+		tty_spawn_id for this purpose.
+
+11/4/92 3.24.0	After problem reported by James Ward <jew@sunquest.xcom> added
+		to man page describing delays required by hardware such as for
+		UART switching.
+
+		Recoded all \C sequences as \### in examples and man page in
+		anticipation of them going away in next version of Tcl.
+
+		Switched to printing errorInfo during errors instead of the
+		command and only the top-level error message.  Since this
+		includes entire stack, this should be very helpful.
+
+		J. Cazander <cazander:pasichva via serigate@phcoms.seri.
+		philips.xnl> reported that purify found a write beyond the end
+		of an input buffer.  Lucked, it was just before a double-word
+		boundary, so it probably isn't a problem.  I fixed it anyway.
+
+10/9/92	3.23.1	Tor Lillqvist supplied support for HP 8.0.7 in POSIX-mode, and
+		a bugfix for POSIX tty mode switching
+
+10/8/92	3.23.0	Larry Rogers <lrr@Princeton.XEDU> reported that "weather" blew
+		up in spawn.  I'll add a catch-all to the script to report
+		similar problems (out of ptys, processes, etc.)
+
+		Ting Leung <tleung@bnr.xca> notes that log() in human_write can
+		receive a 0 (domain error).  Fixed unit_random to avoid that.
+
+		Tony Primavera <aprima@xox.ssc.af.xmil> notes that the sample
+		archie script needs to understand mcgill's limit of 10 users.
+		Tor Lillqvist <tml@tik.vtt.xfi> noted that a lesser-used
+		pattern	("unknown...") is incorrect.
+
+		Grant Taylor <gat@pecan.cray.xcom> found a problem when forking
+		(using Expect's fork) multiple processes, each of which spawned
+		something.  In the BSD pty support, I had used the pid to build
+		a temporary file for testing the pty before actual use.  When
+		multiple processes tried to use the same tempfile, it blew up.
+
+8/12/92	3.22.13	Corey Satten pointed out that -u on cat caused kibitz to slow
+		down on Ultrix.  I see the same behavior on SunOS.  I added an
+		option to fix it for systems that need it.  Corey also noted
+		arg miscounting in kibitz, and pointed out that world-readable
+		fifos could be a security problem.  He gave a fix for this and
+		also a fix to force ptys to be put into raw mode.
+
+		Terrence Brannon <tb06@pl122e.eecs.lehigh.xedu> reported rftp
+		referenced the undefined variable 'transfer'.  Turned out to be
+		a bug in the code to handle symbolic links.
+
+7/20/92 3.22.12	Added O_NOCTTY (if defined) in pty_bsd.c to avoid gaining
+		control terminal while testing pty when running as daemon.
+
+		At request of Michael D. Riley <riley@mbeya.research.att.xcom>
+		added explanation to man page - how expect_after/before deal
+		with spawn_id.
+
+		Charles Hannum discovered the problem with AIX (see earlier)
+		was a missing "extern" in the errno declaration.  Also, the
+		compiler was sensitive to a lack of access to the defn of
+		struct expect_special.
+
+		Dave Coombs gave me yet another fix for the weather server to
+		accomodate its ever continual change.
+
+7/2/92	3.22.11	Yet more work.  Discovered that SunOS and Ultrix really like
+		setpgrp(0,0) much better than setpgrp(0,getpid()) but the
+		manual doesn't describe well why this seems to work better.
+		(The old call worked inconsistently.)
+
+6/30/92	3.22.10	Did more work on modifications to dissolve connection between
+		stdio and devtty.  Eventually, I'd like to add a separate
+		spawn_id for devtty (expect_devtty?).
+
+6/5/92	3.22.9	Hansel Wan <hhw0@gte.xcom> noted that $errorInfo was clobbered
+		by prompt1.  To prevent this, I added a default definition
+		for prompt1 (and prompt2 while I was at it).
+
+		Unnati Amin <uxa@po.cwru.xedu> noted that the example scripts
+		checked for $ in prompts which didn't work.  This bug was
+		created when $ was turned into a "match end-of-input" char
+		in the transition from v2 to v3.  Solution: backslash the $.
+
+		A few parts of code assumed spawn_id was always stdin, which
+		caused "send" to send to stdout, which meant succeeding
+		expect's hung, waiting forever.  Fixed is_user macro.
+		This was a problem with scripts that redirected stdin or
+		somehow reused fd 0.  Surprising that no one ever did that
+		before - also surprising that it didn't bother cron jobs.
+
+6/2/92	3.22.8	Man pages fixes from Matt Crawford crawdad@fncent.fnal.gov.
+
+5/12/92	3.22.7	Missing ; in Makefile, screwed up chmod.
+
+		Fixed bug that caused interact to think the modes had changed
+		when they hadn't.
+
+5/11/92	3.22.6	Added regression paper to ftp archive - published in the 1992
+		USENIX San Antonio Proceedings.
+
+		Swapped setpgrp and fork in disconnect command for sysV88.
+		According to Dave Schmitt <daves@techmpc.csg.gss.mot.xcom>,
+		original code (right out of Stevens) starts the child with
+		closed stdio fds.
+
+		Fixed bug in interact that changed /dev/tty modes even if
+		interact was used to connect two completely different ttys.
+		Had never been a problem before, but today I wrote some code
+		that actually calls interact from cron!  Also, copied the
+		experimental fix from 3.22.5 to inter_poll.
+
+		Jeremy Nussbaum <jeremy@world.std.xcom> says cat needs "-u" in
+		kibitz for his HP 8.0 system to work.  I wonder why this has
+		never been a problem on earlier HP and other systems?
+
+		Forced Makefile to mark scripts executable.
+
+4/12/92	3.22.5	Fixed bugs reported by Matt Ranney <mjr@uther.Calvin.XEDU>
+		including a syntax error (!) in expect.c on ecases_inuse.
+		I didn't even compile this before pushing out?  He also noted
+		some # were not in column 1.
+
+		I put in an experimental fix to interact (only in select
+		version currently) to fix when pattern matching from master
+		and user needs to continue typing in order to complete match.
+
+4/3/92	3.22.4	Charles Hannum (mycroft@gnu.ai.mit.edu) pointed out that I
+		screwed up a comment in the brand new pty_aix3.c.  He also gave
+		me a fix for an arg-less expect, which did a malloc(0).  And
+		he said that AIX ptys return EOF in yet a new way - read()
+		returns -1 with errno == 0.  Yuck.
+
+3/29/92	3.22.3	Jay Schmidgall gave me yet another pty_aix3.c.  He also gave
+		ifdefs for POSIX terminal support.
+
+3/18/92	3.22.2	Jay Schmidgall <shmdgljd+@rchland.ibm.xcom> modified pty_sgi3.c
+		to make a pty interface for recent versions of AIX.
+
+		Steve Summit <scs@adam.mit.xedu> noted that "trap 0" could
+		actually call signal(0...)
+
+		Martin Leisner <Martin_A._Leisner.Henr801C@xerox.xcom> noted
+		that rftp was broken.  It seems I never handled symlinks.  They
+		are interesting.  You can't tell from the listing whether they
+		are files or directories, so you just have to blindly go ahead
+		and assume it's one or the other and see what happens!
+
+3/11/92 3.22.1	In talking to Dave Schmitt ,daves@techmpc.csg.gss.mot.xcom>,
+		realized the documentation for wait had never been updated
+		from the way it used to work in v2 (returning any pid).
+
+3/11/92	3.22.0	Another question from Ron, prompted me to find another bug.
+		interact -o wrongly manipulated the user buffer at one point.
+
+3/10/92	3.21.0	Ron Young <ron@nevada.xedu> found that spawn failed on a
+		DECstation 3100 running Ultrix 4.2.  I had forgotten to test
+		that cmdfile was valid before comparing against stdin in fix
+		related to fflush in 3.20.0.
+
+		While I was on a DECstation, I noticed that it does not accept
+		setpgrp(...,0).  Changed 2nd arg to getpid().
+
+3/6/92	3.20.2	Stefan Farestam <farestam@orion.cerfacs.xfr> provided a new
+		version of pty_sgi.c which uses _getpty.  I renamed the old
+		one pty_sgi3.c
+
+3/3/92	3.20.1	Brian Woodson requested I update the dates and version numbers.
+
+3/1/92	3.20.0	Prompted by a question from Ken Mandelberg, added -raw to
+		noidle and kibitz script.
+
+		Fixed fflush(cmdfile) again, having been authoritatively told
+		by net wisdom that there is no way to portably fflush a shared
+		read-stream. (I take back my claim about a bug in HP's fclose!)
+
+		John Sellens gave me some more fixes for non-DEC MIPS OS.
+
+2/22/92	3.19.1	John Sellens <jmsellen@watmath.waterloo.xedu> gave me a bug
+		fix for NOWAITPID.
+
+2/21/92 3.19.0	Found a bug in HPUX fclose!!  It moves the I/O pointer in the
+		shared file table entry!  This explains the symptoms I reported
+		earlier.  Fortunately, it's easy to code around (by me - it is
+		no longer necessary to fudge the scripts).
+
+		Added some stuff to the man page to explain why expect behaves
+		the way it does in an emacs shell window and how to live with
+		it.
+
+2/21/92	3.18.0	Worked on the HP port some more.  The HP causes a real problem
+		by insisting SIGCLD be delivered in order for wait to return
+		a status.  This royally complicated the code, partly because
+		of the special casing all over the place in the trap command,
+		the asynchronous delivery of SIGCLD and also because Tcl itself
+		is not prepared to have system calls be interrupted.  The HP
+		also defines both CLD and CHLD which threw my macros off.
+
+		Anyway, the end result is that on the HP, SIGCLD is ignored.
+		The manual claims wait status will not be delivered but it
+		seems to be anyway.  Good grief!  (Even if it were ignored,
+		it would not be such a calamity, since wait is used mainly
+		to discard zombies on other systems.)
+
+		A remaining problem is that there appears to be some odd
+		interaction, perhaps with fork, such that the script is rolled
+		back at eof if a spawned process happens to exit at the same
+		time.  The solution for now is to exit all scripts via exit
+		rather than letting exit be called implicitly.  There must be
+		some real bug, but I'm unable to find anything after lots of
+		testing, line and Saber.  At the moment, I'm highly suspicious
+		of the HP itself rather than expect.
+
+		Bob Proulx and Jeff Okamoto supplied me with patches for
+		inter_select.c.  HP transmits some pty interactions via the
+		exception field in select.
+
+		Michael Grant gave me a mod to recognize ~ in the logfile and
+		debug commands.
+
+2/17/92	3.17.1	Brian Keves <keves@meaddata.xcom> pointed out that the man page
+		still referred to "expect_match" instead of "expect_out".
+
+2/12/92	3.17.0	Eric Arnold <Eric.Arnold@corp.sun.xcom> ran into a problem
+		when running in the background.  interact did ioctl(0...)s to
+		change the terminal mode, ignoring the -u flag.
+
+		Fixed a bug in kibitz which blew up when asking for a password
+		due to a spelling error.  The drawbacks of interpreters...
+
+2/4/92	3.16.3	Dongchul Lim <lim@doctor.chem.yale.xedu> noted that scripts can
+		hang in the background.  I had assumed isatty(0) was enough to
+		contrast bg/fg but it returns 1 if the script was started with
+		a & from the terminal.  I added code to watch if any ioctl(0)s
+		were done.  If so, than it is safe to do more, in particular
+		in the exit handler to reset the terminal modes.
+
+1/28/92	3.16.2	Fixed a bug on SV systems causing errors when trying to do
+		further reads after a SIGCLD had already arrived on a spawn_id.
+
+		Peter Funk <pf@artcom0.north.xde> gave mods for SCO XENIX 386.
+
+1/24/92	3.16.1	Oops.  Forgot to add pty_svr4.c to shar.
+
+1/13/92 3.16.0	Karl Lehenbauer <karl@sugar.NeoSoft.xcom> a tiny change for
+		getting a clean compile on SCO 3.2.2.
+
+		My getimeofday-avoidance code wasn't right, sigh.  Kibitz
+		noticed.  Fixed two other bugs in kibitz - password request
+		was for wrong user and it timed out but shouldn't have.
+
+		Note: seems to work fine with new version of Tcl: 6.2
+
+1/13/92	3.15.1	Added a bit of code to avoid gettimeofday system calls when
+		timeout == -1.  Fixed minor bugs in kibitz relating to cleaning
+		up and returning error messages.
+
+		Redid support for stdlib.h including making it default to fix
+		problem in Ultrix 4.2 reported by Oliver Kretzschmar <viskretz
+		@ikesg1.energietechnik.uni-stuttgart.xde>.		
+
+		Ian Johnstone <ianj@sequent.xcom> said his system (DYNIX 3.2)
+		needed an additional include <ctype.h> in inter_select.
+
+		Dave Coombs <cme.nist.xgov> added logic to test/weather to
+		accomodate a new feature in the weather server.
+
+		Hal Peterson fixed some SV code that I just added for handling
+		SIGCLD properly.  He made the Cray-extra-child timeout in half
+		the normal timeout to allow distinguishing between eof and real
+		timeout.  Finished rest of Jeff Okamoto's fixes for HPUX.  
+
+		Wally Strzelec <packman@tamuts.tamu.xedu> provided mods for
+		Amdahl which has its own pty-handling functions.  Ifdef'd into
+		pty_usg.
+
+12/30/91 3.15.0	Fixed a bug that struck when eof occurred when reading from
+		multiple processes simultaneously and no user-supplied eof
+		handler.
+
+12/26/91 3.14.1	Ted Gibson <tgibson@logdis11.hq.aflc.af.xmil> gave me some mods
+		for a 3B2 having to do with termio vs termios, etc.
+
+12/24/91 3.14.0	Deprecated expect 2.  Expect 3 is now the official version.
+
+		Parag Patel <parag@netcom.netcom.xcom> gave me some #includes
+		necessary for A/UX 2.
+
+		Brian Woodson noticed "send a b" generates incorrect debug
+		output.
+
+		Working with Jeff Okamoto to run expect on HP/UX 8.0, we fixed
+		SIGCLD catching (he says HPUX doesn't ignore them by default?),
+		obviating longjmp from stomping locals, fixed a bug in cmdWait
+		that would prevent the wait status from being collected in
+		rare situations.
+
+12/17/91 3.13.1	James Davis suggested fixing Makefile to handle case where no
+		example scripts should be installed.  I added similar logic
+		for script man pages.
+
+		Pete Siemsen fixed a bunch of things in the Makefile including
+		where to get expect when invoking fixline1.  He suggested defs
+		for supporting install and multiple MAN targets.
+
+12/12/91 3.13.0	Matthew Freedman <mattf@cac.washington.xedu> noted mismatch
+		between lib man page (said "stty_init") and lib code (said
+		"exp_stty").  He also found a screwup in the library such that
+		the pty slave wasn't being set up correctly.
+
+		Added note to kibitz man page on how to kibitz with 3 or more.
+
+12/12/91 3.12.0	"expect *" worked incorrectly if it was first expect after
+		spawn, due to buffer not being initialized.
+
+		Added a good example for "expect -continue" to man page.
+		Added an FAQ about a gcc problem that seems to be common.
+
+12/11/91 3.11.2	James Davis noted I forgot to put kibitz.man in distribution.
+		I changed kibitz to read domain from resolv.conf instead of
+		calling domainname(1) for systems upon which NIS domainname
+		differs from Internet.
+
+		Pete Siemsen <siemsen@barnard.usc.xedu> noted slight error in
+		libexpect man page.
+
+12/10/91 3.11.1	A couple tiny mods to the Makefile courtesy of James B. Davis
+		and Michael Grant (guest worker from Sun, temporarily at
+		<mgrant@xdr.ncsl.nist.xgov>.  Both of them also noted a problem
+		caused by incorrect installation of gcc that caused expect to
+		say "ioctl(set): Invalid something or other" upon exit.
+
+		Fixed complaint about exit() while compiling without STDC.
+
+12/9/91 3.11.0	beta!
+
+		Hal Peterson provided fixes for UNICOS 6.1 and 7.0 on both
+		CRAY-2 and CRAY Y-MP.  He also fixed a problem in interact
+		where malloc(0) could've occurred.
+
+		Added support for allowing user to set interpreter prompt.
+
+		Added forgotten -d flag to match_max in rftp script. 
+		Made kibitz understand user@host.
+
+		Expect's internal buffer-full-handling incorrectly copied
+		the latter buffer half beginning from the end of the buffer.
+
+12/5/91 3.10.1	Massaged Makefile to allow for more flexibility in
+		installation, especially with regards to scripts.  #! is now
+		reset.
+
+		Added "kibitz", a really cute script to let two people control
+		one program.  Example users are for one person to help another
+		remotely, logging a conversation (run emacs or whatever inside
+		kibitz and your conversation can be logged, scrolled backwards,
+		etc., or of course, playing games together.
+
+12/4/91	3.10.0	Tightened up arg checking for "wait" - it core dumped when it
+		should've said "syntax error".
+
+		Rick Cady <rickc@nsd.3com.xcom> noted minor inconsistency in
+		man page describing strace.
+
+		I fixed a bug that prevented "system stty -echo raw" from
+		working.  The raw data was clobbering the -echo data.
+
+12/3/91	3.9.0	Brian Woodson noted that "close -i ..." evoked a syntax error.
+		I had parsed the arguments incorrectly.
+
+		After the nth request, I finally set up pub/expect/scripts as
+		a directory for scripts.
+
+12/2/91 3.8.0	Phil Sheperd <pshepher@loki.uni.edu.xau> fixed a major bug in
+		exp_spawnv() preventing one side of the pty from being set up
+		correctly.  Thus nothing worked!  He also reported that his
+		system didn't have strdup, so I added an explicit defn of it.
+
+		James B. Davis fixed a couple nroff-bugs on the man page, and
+		said someone already gave him a dump script (see below).
+
+		Richard (R.C.) Vieregge <richv@bnr.xca> found a $ was missing
+		from test/ftp.exp.
+
+11/22/91 3.7.2	James B. Davis <james@solbourne.xcom> straightened out a couple
+		things in the Makefile and asked if anyone had written a script
+		for dump.
+
+		Jeff Okamoto <okamoto@hpcc25.corp.hp.xcom> had a couple changes
+		for HPUX 7 and 8 compat, involving termio stuff.
+
+		Prompted by Andy Norman, added note to man page describing how
+		to disable all argv processing while using #!.
+
+		Converted passmass and rftp over to new version.
+
+11/15/91 3.7.1	Brian Woodson asked me about the Tcl_WaitPids "got unknown
+		process" panic.  This is a Tcl bug that John has promised
+		to fix.  I'll document how to avoid it in the man page.
+
+		Incidentally, I'm going under the knife tomorrow for three
+		torn cartilage in my wrist.  The doctors say it may be a couple
+		days to couple months.  Until I get back, hang in there.
+
+11/13/91 3.7.0	Yet another bug discovered (and fixed).  "expect eof" was
+		failing to remember the buffer, and expect_out(buffer) was
+		empty upon return.
+
+		Brian Woodson noted I forgot to document the -i flag of close.
+
+11/12/91 3.6.0	Sean Cunningham <sean@moorenet.xcom> reported that he couldn't
+                open /dev/tty from 'at'.  'spawn' was incorrectly not executing
+		code to claim it was a controlling tty.  BSD only.
+
+11/11/91 3.5.1	Brian Woodson notes that version 2 and 3 treat the following
+		differently.
+
+			proc p {} {spawn s}; expect
+
+		In v3, spawn_id is locallized by the proc, and thrown away when
+		p returns.  Unfortunately, in v2 due to some sloppy coding on
+		my part, spawn always affected the global value of spawn_id.
+		This differed from the handling of other variables, and in v3,
+		this unusual behavior had to go, because the multiprocess
+		handling and the large number of variables implicitly set
+		(especially by the expect command) demanded that I be more
+		systematic about how this was done.
+
+		Since I never depended on this behavior, I never documented it
+		as being something you should rely upon.  Alas.  To fix it, add
+		the line
+
+			global spawn_id
+
+		to the beginning of any proc that calls spawn and needs the
+		value of spawn_id implicitly defined outside of the proc.
+
+11/6/91	3.5.0	Drew Whitehouse <Drew.Whitehouse@anu.edu.xau> hit a bad pointer.
+		I forgot an initialization in expect.c which caused problems
+		when an EOF occurred which had no eof pattern.
+
+11/2/91	3.4.0	Added FAQ from various questions people have sent me and my
+		replies.  Made CONVERTING file on converting from 2 to 3.
+
+		Nelson H. F. Beebe <beebe@math.utah.xedu> found a missing
+		declaration for exp_tty_original in bye() of main.c.  How come
+		the Sun C compiler doesn't complain about this!?!!?
+
+		Nelson also reported that SunOS 4.0.3 had a problem including
+		varargs.  It turned out that old varargs had check for
+		reinclusion, and tclInt.h also includes it.  So I added an
+		#ifdef va_dcl and put my inclusion after tclInt.h.
+
+10/31/91 3.3.0	Converted most of the examples.  Three more to go.
+		Worked on man page some more.
+
+		Modified expect so that if timeout > 0, and nothing in the
+		buffer matched, it will force a read, no matter how long the
+		preceding code took.  This may be hard to understand, but is
+		the intuitive behavior that I always desired.
+
+10/30/91 3.2.0	Fixed bug in eof handling.  Converted some more of the
+		examples, and added to Makefile.
+
+10/29/91 3.1.0	Fixed slight bugs in tty mode switching, pty initialization
+		(via stty).
+
+		Fixed expect library.  Fixed compatibility code for non-BSD
+		systems.  As usual, I could only test it so far, not having
+		all these systems at my disposal.  I don't expect major
+		problems though, since the basic functions I depend on haven't
+		changed.
+
+		Completely rewrote handling of continue, return, etc in
+		expect, interact, interpreter.  It's actually systematic now.
+
+		Checked with John O. about some code to bounce wild return
+		codes, which he said was a mistake and would remove, so now I
+		can pass my own return codes different from Tcl's.
+
+To get | to return ->	TCL_RETURN	TCL_OK		(no return)
+       V
+    expect		return		default		continue -expect
+    interact		return -tcl	return		default
+    interpreter		return -tcl	return		default
+
+		What this table says is, to get "interpreter" (for example) to
+		return TCL_RETURN to its caller, you must say "return -tcl",
+		because "return" makes it return TCL_OK.
+
+		The "argumented" versions are considered to be the uncommon
+		form.  In particular, I'd be surprised if anyone ever uses
+		the -tcl argument, but it's there for completeness and
+		consistency now.
+
+		Put together a FAQ.  Needs more work, but hopefully worthwhile
+		as is.
+
+		Computing Systems with Expect article appeared a couple days
+		ago.  How ironic that it describes the old version of Expect.
+		Nonetheless, it looks ok.
+
+10/25/91 3.0.0	alpha!
+		First release of Tcl-6.0-ready code.
+		It might fly for a couple seconds.
+
+	Here is a quick list of changes.  Besides Tcl incompatibilities, Expect
+	incompatibilities are flagged below as:
+
+	**	major - scripts definitely won't run if they depend on this
+	*	minor - scripts probably will run but there is some subtle
+		change that should be examined).
+
+	**	Select renamed 'ready' and undocumented.  Seems pointless now.
+
+		Added support to expect command for waiting on patterns from
+		different processes.  The old version implemented this via
+		'select' but but it is much simpler via expect.  Added -i to
+		a number of commands to signify a spawn_id which overrides
+		the variable.
+
+		Added any_spawn_id to match any spawn_id.
+		An explicit null pattern, forces a spawn_id to be considered
+		when all it can possibly match are any_spawn_id patterns.
+
+	*	output is no longer flushed to expect_match upon timeout. 
+		May be multiple buffers now, so it doesn't make sense to
+		flush just one.)  -n was added to disable transfers from input
+		buffer to expect_match var.  I suspect it will only be used
+		for experimentation.
+
+		Added expect -re for regular expressions.  Added expect_out
+		array to retain indices and strings of partial matches for
+	**	for both glob and re.  expect_match has been renamed
+		expect_out(buffer).
+
+		A la Tcl, added -nocase for both types of patterns.  (Oddly,
+		Tcl's case only does it for regexps.)
+
+		By popular demand, unanchored glob patterns.  Old patterns
+		will continue to work, since earlier interpretation was much
+		stricter.  Unfortunately, unanchored matches make certain user
+		errors easier.  For instance, people will send answers before
+		seeing all of the question.  Typically, output can 'look'
+		ugly, as answers land in the middle of other things.
+
+		To anchor patterns, use ^ in beginning and/or $ at end.
+
+		Added expect_out(spawn_id) to report which spawn_id was read.
+
+		Made expect and variants understand all args as one arg.
+
+		Added 'default' pattern.
+
+		Added continue_expect command.
+
+		Added expect_before, expect_after commands which take same
+		args as expect, but continue to stay in effect for all expects.
+
+	**	Added match_max command, deleted it as a variable.  The old
+		way was too coarse for use over multiple spawn_ids.  With no
+		arg, returns current max.  Takes -i flag and -d for default.
+
+		Added globbing to spawn command.
+
+		Added optional -i spawn_id to wait.
+
+		Added optional -i to send (and all its variants).
+
+		Renamed trace to 'strace' since it conflicts with Tcl's new
+		trace command.  Since 'trace' traces variables, I figured
+		'strace' wasn't too bad (for "statement trace").  I felt
+		obliged to make it short and not as obliged to make it as
+		meaningful since it will probably invariably be typed by hand.
+
+		Made timeout == -1 mean infinity.
+
+		Made interact do pattern matching in both directions via
+		use of -o flag.
+
+		Added -F flag for convenience.  If -f or -F used, interact
+		can no longer be overrun.  In particular, if more characters
+		arrive then match a pattern, remaining characters will be
+		buffered rather than thrown away (old behavior).
+
+		Patterns may now be substrings of one another.
+
+		Made interact optionally take all args as one.
+
+		Default action is now 'interpreter' (see below).
+		interpreter now forces cooked mode, and echos results
+		so you don't have to constantly say "send_user ...\n"
+
+	*	Interact reads characters that have been buffered but not
+		matched by expect.  And vice versa.  Does anyone care?
+		(My rogue script did.)
+
+		From discussion with John Conti, I decided to make
+		'interpreter' a separate command to start up interactive
+		command processor.  Changed default action in interact to this.
+		Added eval depth and event id to prompt to interpreter.
+
+		Added expect_library which contains path for commonly
+		sourced expect scripts.  Automatically source expect.rc
+		out of expect_library unless -N given.  Automatically source
+		~/.expect.rc unless -n given.
+
+		Added expect_version command to print and/or verify script
+		is compatible with running expect.  Tcl version is also tested.
+		Felt it was worth making this a command because it's such a
+		pain to tear apart version strings.
+
+		Tcl's close and exit are both subsumed by expect's commands
+		of the same name.
+
+		Rewrote mode switching code so that "system stty" is handled
+		specially.  This allows interact and interpret to get the modes
+		they want, without burning the user.  It is now much easier
+		to leave expect in raw mode all the time, but the choice is
+		up to the user.
+
+		Added vgrindefs, courtesy of Brian Fitzgerald.
+
+9/23/91		Tcl 6.0 released.  This new Tcl has some incompatibilities
+		with the old Tcl, so as long as everyone is changing their
+		scripts already, I'm taking the opportunity to make some
+		incompatible changes to Expect that I've wanted to do for a
+		long time.
+
+9/11/91 2.67	Ed Klein <eklein@syrinx.umd.xedu> added support for SVR4 in the
+		form of pty_svr4.c and mods to command.c.
+
+		Added explanation to man page of how to create unreadable but
+		executable scripts.  (No, chmod 111 doesn't work.)
+
+		Mark Diekhans <markd@grizzly.XCOM> pointed out to me that there
+		is a potential problem with the trap command:
+
+		"There is no control over when the signal will cause Tcl_Eval
+		to be executed.  There is a chance that code in the Tcl library
+		will be executing when the signal comes in and the interpreter
+		data structure will be in an inconsistent state.  This could
+		cause all sorts of nasty things to happen.  In our Extended Tcl
+		(4.0) we added signal handling. but the way we implemented it
+		was to have the signal handler set a global flag.  We modified
+		Tcl_Eval to check the flag after it finishs executing each
+		command.  If the signal came in, Tcl_Eval then returns an error
+		such as: "SIGINT signal received".  Signals may then be caught
+		with the catch command and processed."
+
+9/10/91 2.66	Don Jackson <Don.Jackson@Eng.Sun.XCOM> found a syntax error in
+		the usage error message of the example ftp-rfc script.
+
+		Marty Olevitch <marty%cosray@wuphys.wustl.xedu> provided mods
+		to support MORE/bsd.  Namely, added #include types.h to
+		expect.c and extern int errno to a number of files.
+
+		Scott Hess <scott@nic.gac.xedu> noted a potential problem in
+		interact.  Since interact only checks patterns at beginning
+		of reads, user can conceivably type fast enough so that
+		patterns are typed in the middle of a read.  In reality this
+		doesn't happen, but Scott was driving one expect with another
+		expect and in this way provoked the behavior.
+
+		The solution is to read chars one at a time, either by
+		read(,,1) or buffering in a stdio-like way, but I'm not going
+		to do that because the code should really be rewritten entirely
+		and it just isn't worth it, since it is so easy to get around
+		at the user level.
+
+		Steve Legowik found that spawn-disconnect sequences fail.  The
+		pty testing I added in version 2.55 causes expect to regain the
+		slave as a controlling tty, which generated SIGHUPs.  If anyone
+		knows a clean way to avoid regain controlling ttys, let me
+		know.  For now, I just set SIGHUP to SIG_IGN in the disconnect
+		command.
+
+8/14/91 2.65	Old passmass script changed root password.  I renamed it to
+		passmass.old, and made a new one which works for any account.
+		It also supports yppasswd, telnet/rlogin, different names for
+		accounts on different machines.  Handles VMS machines, too.
+
+		Added Computing Systems paper to expect distribution and moved
+		all expect-related things to separate expect directory in our
+		ftp directory.
+
+8/5/91	2.64	Achille Petrilli <achille@miss.cern.xch> found that on an SGI,
+		the expect command ocassionally returned "no more processes".
+		He traced the problem back to O_NDELAY in the open, which was
+		taken as-is from the man page, by someone else who's code I
+		didn't look at too closely at the time.  The result works now.
+		Oddly I thought I fixed this error myself when the SGI support
+		was first installed, but I cannot find it.  I evidentally
+		screwed up.
+
+7/31/91	2.63	Steve Legowik <legowik@cme.nist.xgov> wanted to implement
+		callback by having a modem dial out and NOT go away, but
+		interact in the reverse direction.  I added "interact -u" to
+		support the idea of changing the user from the default stdio
+		to a second spawned process.  The result is that we can now
+		write a modem callback program that doesn't depend on the cute
+		trick of having getty recognize DTR which only worked when the
+		modem was directly connected to the computer.  In Steve's case,
+		there were several network switches in the way.
+
+		Added "overlay" function which is similar to plain "exec" in
+		shell.  (Too bad Tcl took the name already.)
+
+		Added robohunt scripts to the test directory.  I wrote these
+		back in January, '91 and forgot about them til now.  But I
+		suppose they are illustrative (at the very least of how to
+		generate truly random numbers).  Ha.
+
+7/20/91	2.62	Carl Witty <cwitty@jessica.stanford.xedu> pointed out my fdset
+		implementation (for systems that don't have it) wasted some
+		space.  I had commented it correctly, however, making the
+		incorrect code obvious (except to me).
+
+		Robert Howland <howland@rahjr.ame.nd.xedu> pointed out that
+		expect complained about not running from a real terminal under
+		cron.  Oops!  So I added a test to skip saving/restoring
+		terminal modes when fd 0 is not a tty, since this is obviously
+		pointless.
+
+7/19/91	2.61	Oops.  Forgot to include getline and getline.exp examples even
+		though they have been documented!
+
+7/17/91	2.60	UMich changed interface to weather system necessitating change
+		to weather script.
+
+7/9/91	2.59	Didn't correctly comment things right in Makefile.  Fixed.
+
+		Changed 'close' in gethostbyaddr example to 'catch close'.
+
+6/22/91	2.58	Made new file (pty_sgi.c) for supporting Silicon Graphics ptys.
+		Silicon Graphics select fails to see eof immediately but poll
+		works ok.  Unfortunately, there was an error in inter_poll
+		(bad_io was uninitialized).  Silicon Graphics works now.
+
+		Andy Norman <ange@hplb.hpl.hp.xcom> notes that linking expect
+		with the BSD compatibility library under HP-UX, libc.a must
+		be loaded before libBSD.a.  Modified Makefile to reflect this.
+		He notes that there is a problem with expect not reading an EOF
+		from the current process.  This should go away with HP-UX 8.0
+		when select has been enhanced to flag exceptions in the readfds
+		argument.  Probably inter_poll would work.
+
+		Edward Haines <haines@bbn.xcom> notes that close returns EPERM
+		("Not owner") on his Sun 4.0.3.  This is rather startling!
+		(That's what I get for checking the return value of close!)
+		He said it is possible that they have modified things (viz.
+		DDN X.25 is loaded), but it still sounds incredible.  For now,
+		I told him to either "catch" all closes or to remove the check
+		in the source code.  
+
+		Added example scripts: ftp-rfc retrieves an RFC from uunet
+		via ftp.  archie mails back a listing from the archie server.
+
+		Add the rest of Hal Peterson's changes for Cray support, 1)
+		fixing a problem where spawned processes flushed unread I/O
+		upon process exit, and 2) creating processes with the correct
+		uid.  See his comments in command.c for more info.
+
+6/6/91	2.57	(On Cray) made signal handler declarations right.  Added
+		missing #endif.  Added includes to pty_unicos.c.  Fixed bug
+		in two bugs in CmdSend, one involving send_stderr, the other
+		send_user.  All of these are from Hal Peterson.
+
+		Added gethostbyaddr as example script.  Given an internet
+		address, it returns the domain name.  By querying neighboring
+		hosts if the name server fails, a much higher probability of
+		returning the name is obtained.
+
+5/30/91	2.56	Mispelled "match_max" as "max_match" in rftp script.  This
+		caused files after the 2000 byte mark (per directory) to be
+		skipped.
+
+5/21/91	2.55	Revisited BSD pty code to reject ptys that have either slave or
+		master side already open.  This fixes problems rare problems
+		such as expect not being able to see EOFs from the child proc.
+		(because another process still has the pty slave side open).
+		USG and Cray pty code could probably use this code, too.
+
+		Fixed bug in expect library (lib_exp.c) which caused output to
+		be copied to stderr instead of logfile when logfile_all was
+		set.  Per Sreedhar Muppala <muppalla@nssdca.gsfc.nasa.xgov>.
+
+5/16/91	2.54	Fixed weather script to accomodate occasional Weather Watch
+		that would cause an unexpected initial question to pop up.
+
+5/15/91 2.53	Added comment to BUG section of man page describing pty
+		misbehavior with non-interactive programs (search for "553061"
+		below), as per Hal Peterson <hrp@cray.xcom>.
+
+		Removed note from README about asking Ousterhout for SV TCL
+		at his request.
+
+5/11/91	2.52	Fixed a syntax error that Bruce Larson <ires@kaspar.ires.xcom>
+		found in inter_poll.c
+
+4/23/91		Computing Systems accepted paper on Expect for issue 4.2.
+
+4/18/91	2.51	Added some example scripts:
+		weather - retrieves weather forecasts from National Weather
+		Service via University of Michigan server.
+		rftp - ftp a directory hierarchy (i.e., recursively).
+
+4/18/91	2.50	Changed timeout to apply to total time in expect rather than
+		per read().  Original behavior hung forever when my modem test
+		script started listening to a modem than spit out 1 spurious
+		character every 10 seconds (very consistently).
+
+		Hal Peterson <hrp@pecan.cray.xcom> noted that exp_spawnv's args
+		didn't match documentation.  Fixed in favor of documentation.
+		Several other funcs don't match header file (but typechecking
+		is avoided during compilation), because it was too hard for me
+		to make the header file ANSI compliant and support varargs 
+		(which is undeniably more portable than stdargs at this point).
+		Fixed prototype declarations (again) in expect.h for C++ and
+		Standard C.  Verified with GNU, G++ and Sun C (proto-less).
+
+		Added exp_disconnect to library.  Moved alarm calls closer
+		to read() to tighten windows.
+
+4/11/91	2.49	Changed passmass script to use timeout of 1000000 instead of
+		10000000000 after discovering that Ultrix sleep(3) doesn't
+		sleep at all for large values!
+
+		Added support for systems without dup2 (SVR2) per
+		<elston@edwards-tems.af.xmil>.
+
+		Added test/Makefile to shar as per Chris Pribe
+		<cpribe@park.bu.xedu>.
+
+4/4/91	2.48	Fixed possible problem with poll in inter_poll.c for systems
+		that check for a valid address even though no members are used.
+
+3/27/91	2.47	Added support for Cray Unicos 6.0, which of course is different
+		from Unicos 5.1 (which was different from everything else)!
+		This and other minor bugs fixed courtesy of Pete Termaat.
+
+3/19/91	2.46	Removed a "feature" which caused patterns with no whitespace
+		not to be run through SplitList.  While not documented not to
+		do so, this was mystifying even to me when I saw it.  For
+		William Waite.  The result actually simplified the internal
+		handling of multiple patterns, removing some excessively
+		complex logic that I thought would be helpful for speed, but
+		that in retrospect, was not that important.
+
+3/16/91	2.45	Added my own definition of FD_SET, fd_set, etc, test for
+		SIGABRT, and support different types of signal arg func
+		definitions to support SunOS 3.5 as requested by William Waite
+		<waite@scotty.colorado.xedu>.
+
+3/14/91	2.44	Removed redundant def'n of pty_stty in pty_usg.c, redef of
+		sprintf and added signal.h to command.c to make compiles
+		cleaner on SV3 and HPUX machines.  All compliments of Mike
+		Gourlay.
+
+3/10/91	2.43	Added -s (for slow) and -h (for human) flags to send.  This
+		had been requested by several people including Frank Terhaar-
+		Yonkers (who actually wrote and tested a "send_slow" command),
+		and Steve Simmons who suggested the "human" option (over a year
+		ago), and Brian Woodson (brianw@swqa-sun.ESD.3com.com), who
+		requested both!  Thanks to NIST statistician, Keith Eberhardt,
+		who taught me about the Weibull Distribution.
+
+		According to Jim Thomas <jthomas@nmsu.xedu>, 3b2 requires
+		defines for R_OK and W_OK.  Added to pty_usg.c.
+
+		Added support for "-" as file name on command line to mean
+		stdin as requested by Steve Clark <clark@cme.nist.xgov>.
+
+		Wrote passmass (change root password on a set of machines) as
+		requested by Ken Manheimer <klm@cme.nist.xgov>.  Added to test
+		directory.
+
+2/21/91 2.42	Removed reinstallation of signal 0 in signal handler.
+
+		Added hook for setting initial pty parameters when started in
+		the background.  Should've done this a long time ago, but I
+		was never really happy with my solution and had hoped I would
+		think of a nicer method.  I only hope this is clean enough.
+
+2/10/91	2.41	Added buffer_full keyword to solve Brian Fitzgerald's problem.
+		It disables "forgetfullness" so that when expect's internal
+		buffer hits match_max, whatever it has returns at that point.
+		Didn't add this to the library version, because I want to think
+		for awhile about the cleanest way to do it.
+
+2/4/91	2.40	Per Brian Fitzgerald (fitz@mml0.meche.rpi.edu), fixed error in
+		interact example on man page which incorrectly implied that
+		"kill" was built-in.
+
+		Added fork/disconnect functions.  This solved the problem of
+		Jerry Friesen (jafries@snll-arpagw.llnl.gov) who wanted to run
+		an expect script that asks for a password and then goes to
+		sleep for awhile before waking up to run in the background (to
+		run a program using Kerberos).
+
+1/30/91	2.39	Per Jim Johnson (jaj@mlb.semi.harris.com), added declaration
+		and documentation for exp_pid in libexpect.
+
+1/10/91	2.38	More mods from Frank Terhaar-Yonkers.  Also, some requests
+		from Pete TerMaat (pete@willow.cray.com) for features:
+
+		1) a single-step facility.  Yeah, that would be nice.  No
+		ideas on how to do this easily.
+
+		2) Generate scripts automatically after watching a session.  
+		This is hard.  Read more about this in the FAQ.
+
+1/10/91	2.37	Added support for Cray Unicos 5.1, all courtesy of Frank
+		Terhaar-Yonkers (fty@sunvis.rtpnc.epa.gov).  Most of it had to
+		do with pty support.
+
+1/8/91	2.36	Modified expect.h to support C++ and ANSI prototypes.  Added
+		appropriate example in test directory based on chesslib.c.
+
+1/7/91	2.35	At the request of Jan Norden (jano@imdpy1.im.se) added
+		NO_MEMCPY and NO_STRING_H defines for Pyramid.
+
+1/3/91	2.34	Added a check to protect against a longjmp occurring between
+		i_read and alarm(0).  Didn't think this would be a problem but
+		evidentally a function return modifies the stack, so it cannot
+		be returned to again.  Drat!  This appeared in the robohunt
+		script I wrote which plays hunt automatically and uses 1
+		second timeouts.
+
+12/19/90 2.33	Add signal to sighandler, to reinstall signal for those systems
+		that need it.
+
+12/12/90 2.32	Removed test for args to expect.  I only recently realized that
+		no args still allows a valid way to check for timeout and eof!
+
+12/6/90	2.30-1	Mike Gourlay (mike@penguin.gatech.edu) found and fixed quite a
+		few SV-related problems that I had introduced since Clem's
+		fixes.  We eventually got it to run on his HPUX machine, a
+		mixed breed of BSD/USG stuff.  But spawning a shell worked but
+		always produced a complaint about "no access to tty" which we
+		were never able to get rid of, and he had a problem with
+		exp_fexpect (but not exp_expect), although it still isn't clear
+		if that was expect's fault.  He said he would speak to some HP
+		engineers about what he found.
+
+12/5/90	2.29	Fixed a malloc off-by-one bug in new C library.  After
+		contemplation, revised interfaces.  Decided that rather	than
+		following the original 'expect' style, it should be more like
+		what a C programmer is used to, so I made the file descriptors
+		be parameters to exp_expect rather than globals, added an
+		exp_popen which is a popen equivalent, and added exp_fexpect
+		versions which are stream equivalents.
+
+		Am not happy with exp_fexpect.  It is much less efficient than
+		exp_expect, because there is no way to (portably) get fread()
+		to return the way read() does, with less then the number of
+		characters you supplied a buffer for.  Instead, I have to call
+		fgetc for every char.  Ugh.
+
+		Add a couple new examples, including lpunlock, time.exp,
+		chesslib.c (using file descriptors) and chesslib2.c (which uses
+		stream pointers).
+			
+12/3/90	2.28	Created C library version of expect.
+
+11/29/90 2.27	Fixed bug in interact - when no string actions were defined,
+		the mapping table length wasn't set at all.
+
+		Made interact call printify when debugging so that crlf and
+		other nonprintables are visible.  Fixed bug in printify which
+		interpreted some characters wrong due to parity.
+
+		Added some more examples to the distribution (lpunlock,	dvorak,
+		timed_read) and put in another tip in the TCL HINTS section of
+		the man page.
+
+11/18/90 2.26	Fixed mismatched comment per Craig Warren (ccw@deakin.oz.xau).
+		Also improved man page entry for "interact".
+
+11/17/90 2.25	Added -f (fast) on interact options, and made default case a
+		little more efficient.  Added explicit support for SIG_IGN and
+		SIG_DFL in trap command.  Added ability to specify signals
+		symbolically for portability.
+
+11/15/90 2.24	Craig Warren (ccw@deakin.oz.xau) wanted to exit expect while in
+		interact with a single character.  Dan Bernstein
+		(brnstnd@kramden.acf.nyu.edu) wanted to suspend with a single
+		character.  So I generalized interact's escape character to
+		string-action pairs.
+
+11/7/90	2.23	Tired of getting reports that various (Ultrix 3.1, BSD4.3) C
+		compilers can't handle ternary conditionals returning ptr to
+		func returning void.  Made all (2) such statements into
+		if-then-elses.  Per Steve Simmons (scs@iti.org).
+
+10/8/90	2.22	Allow "log_file" even when no log is open.  This makes user
+		programming a little simpler - they don't have to remember
+		whether they opened the log or not.
+
+9/27/90	2.21	Fixed bug, v2.19 introduced.  debuglog(unknown string) requires
+		a "%s" as formatting for protection against %'s in the unknown
+		string.
+
+9/17/90	2.20	4 syntax errors in interact_poll.c, vik@sequent.com.  Added
+		quotes to all the sends (now that this is more efficient) in
+		the examples and man pages.  Also removed a misstatement in the
+		man page about the behavior of double quotes.
+
+9/15/90 2.19	Removed buffering from send command.  Originally, I buffered
+		the args, so I could do it all in one write.  But to send
+		variables bigger than the buffer didn't work.  I didn't think
+		about this before.  But Joe Gorman
+		(Joe.Gorman@elab-runit.sintef.xno) asked me if you could "send"
+		a file in one command, and of course you can using exec cat
+		as the argument to send, but the buffering prevented big
+		files from being sent.  Anyway, now it works.
+
+9/14/90		Fixed the declarations of nflog and nferrlog.  Added a #define
+		so lack of pid_t could be controlled from the Makefile.  Per
+		Andy Holyer (and@ux.rfhsm.lon.ac.uk)
+
+9/4/90	2.18	Added trap command to catch signals.  This is nice as (among
+		other things) it allows you to turn off the conversion of ^C to
+		timeout which was requested by John Conti <jconti@cisco.xcom>.
+
+8/21/90 2.17	Fixed bug in printify.  Forgot to reset ptr to beginning of
+		print buffer.  Made debugging info wrong.  Possibly screwing up
+		other things on overflow.
+
+		Paper accepted into USENIX LISA!
+
+8/15/90		Cleaned up man page.  Made tabs line things up correctly,
+		finally.
+
+		Found another problem with ptys (at least under SunOS 4.1 and
+		earlier).  When last pty-slave fd closed, any unread output is
+		lost after a short window of time (around 10 seconds on a
+		Sun 3/60).  Sent example ptybug.c to Sun demonstrating this and
+		EIO problem found earlier.  (Service Order #553061)
+
+8/6/90	2.16	Added -f to debug command, -a to log_file command.  This
+		required significant changes, including revisiting all the
+		logging routines, plus miscellaneous output done in special
+		places.  Noted that it cannot be done with getopt, since it
+		could be called during main's getopt, and getopt is not
+		reentrant!  (Guess how I discovered this!!)
+
+		I'm not particularly happy with the design, but maybe others
+		won't be.  In any case, I like the benefit of it and am now
+		glad that -a was asked for.  Per Harry Bochner and Ira Fuchs
+		(fuchs@pucc.bitnet).
+
+		Changed behavior of argv, so that 0 == length $argv when no
+		script/args supplied.
+
+8/4/90	2.15	Added debug command, so -d-ness could be changed while expect
+		is running.
+
+7/20/90	2.14	Fixed small bug in -d output from expect, which	printed ^Z as
+		^:
+
+7/18/90	2.13	Added wait command.  A waitpid/waitspawnid would be nice and
+		cleaner, too, but since csh doesn't need it, it is probably not
+		worth much.
+
+		Consequently, removed SIGCHLD handling from command.c.  It
+		worked under SV but not BSD.  By forcing users to explicitly
+		code waits, resulting scripts are more portable.
+
+		Rewrote rogue example.  rogue sometimes misses EOF (generated
+		by close on our side) and continues reading.
+
+7/16/90	2.12	Removed buffering from variadic log routines.  This was
+		faulting when the buffers overflowed.
+
+		Cleaned up the -d output from expect, so it is much more
+		readable.  For example, control characters are now visible.
+
+7/14/90	2.11	Added declaration for errno, to support 4.3BSD.  Per Alan
+		Crosswell.  Added -i flag and related behavior.
+
+7/12/90	2.10	Fixed bug where timeout = 0 waited forever rather than not
+		waiting at all.
+
+7/11/90		Fixed man page example which didn't include the blank on the
+		end of an ftp prompt.
+
+7/9/90	2.9	Fixed bug in send when spawn_id = $user_spawn_id.
+
+6/27/90	2.8	Integrated some mods from clem cole (clemc@ccc.com) to support
+		System V.3 (386/ix Version 2.02).  Unfortunately, he didn't do
+		"select".
+
+6/25/90	2.7	Test that cmdfile and logfile are open before fclosing in child
+		while spawning.  Per Corey Satten <corey@cac.washington.xedu>
+
+6/24/90	2.6	Pty master returns EIO instead of EOF when pty slave closes.
+		Bug in pty driver?  Until I figure this out, I have put in code
+		to interpret EIO to EOF.
+
+6/21/90		Added new section to expect man page - Tcl hints.
+
+6/14/90		Spoke at USENIX.  Went well.  Added USENIX paper as separate
+		ftp archive.
+
+6/4/90 	2.5	Fixed bug in ^C catching during expect.  Changed man page to
+		accurately describe what ^C does.  Fixed bug that caused "send"
+		to screw up when handed 0 arguments.  All per Harry Bochner.
+
+6/1/90	2.4	Made trailing empty action in expect optional, primarily to
+		make straightline code easier to read.
+
+5/15/90	2.3	Changed expect to strip nulls from program output since there
+		is no way for Tcl to handle them, per Harry Bochner.
+
+5/5/90		Added "send_error" command.
+
+4/26/90		Got USENIX paper back from Kolstad to proof.  Am depressed at
+		how awfully they formatted it.
+
+4/25/90	2.2	Eric Newton found that expect's special variables weren't being
+		found inside of user subroutines.  Had to do with new Tcl,
+		which now differentiates between variables that are undefined
+		vs. empty.
+
+4/24/90		Upgraded Tcl from 2.1 to 3.3.
+
+4/22/90		Added special behaviors of ^C in expect, and when profiling.
+		Profiled rogue (at urging of Ousterhout).
+
+4/10/90	2.1	Added select command.  Added support for user_spawn_id so that
+		you could treat user just like another process (i.e. with send
+		and expect).  Decided to leave send_user/expect, since scripts
+		are more readable with them.
+
+4/2/90	2.0	Changed syntax of expect to provide alternatives (a la Tcl
+		case), per suggestion of John Ousterhout.  Note that this
+		breaks pre-2.0 scripts.
+
+3/31/90		Got great comments from Ousterhout.  (This time he said that he
+		really liked the idea.  Maybe he realizes how much it will
+		promote Tcl!)
+
+3/30/90		Got comments from dpk.  Made me think more about Perl.
+
+3/28/90		Evi said I should turn the paper in unformatted and they will
+		format it.  (She's kidding, I hope.)
+
+3/27/90	1.8	Rewrote interface so that raw arguments can be passed in like a
+		shell.  I'd been thinking about this for some time, but Eric
+		Newton finally prodded me into action.
+
+3/25/90		Got first corrections for paper - from Sue Mulroney!
+
+3/24/90		Observed that it is possible to use the #! syntax with expect.
+		I asked John O. about this (his choice of # as a comment
+		character), and he said it was pure coincidence.  Deprecated
+		request to end scripts in ".exp".
+
+		Ted Hopp volunteered to be my Center WERB reader.
+
+3/23/90		Finished 1st draft of USENIX paper and sent copies to John
+		Ousterhout and panel chair, dpk@morgan.com.
+
+3/20/90	1.7	Deprecated "stty", and added more general "system" command.
+
+		Sent Evi some complaints about the business of not allowing
+		camera-ready at USENIX.
+
+3/17/90		Sent copies of man page to Doug Gwyn and Larry Wall for
+		comments.  Note that gwyn downloaded it.
+
+3/16/90		Am really irritated by USENIX.  My paper has been put in a
+		session against another session, the BSD people.  Furthermore,
+		they called my paper an application, when it is no more so than
+		any other shell or language.  Better I should be in "lessons
+		learned".  But it was too late to change the schedule.  On top
+		of that, our session has four people in it, so I'll have very
+		little time to speak.  Grrrr.
+
+3/13/90	1.6	Added "stty", because without it you can't do things like
+		turning off echo to accept a password.
+
+3/8/90	1.5	Abstract was accepted into USENIX!!!!  Time to start writing
+		it!  Sent man page to Ousterhout.  He didn't seem too
+		impressed.
+
+		Added "send_user/expect_user" after listening to Ken complain
+		about how shell could not do timed reads.  Actually it can, but
+		expect does it much more naturally.  Deprecated echo.  Now, I
+		realize that expect can be viewed as a shell!
+
+		Changed logfile/loguser to log_file/log_user to match all the
+		variables with underscores in them.
+
+		Barry Warsaw asked if there was any way one could execute any
+		command from interact (apparently without any reason in mind).
+		Nonetheless, it is a wonderful idea, and I changed the "abort
+		character" in interact to an "escape mechanism".  After
+		escaping, you may execute any command.  return duplicates the
+		old action of the abort character.  Now you can do interactive
+		job control, recursive interacts, etc.  You can bet I didn't
+		get this right the first time!
+
+		At Scott's request, fixed bug related to pty initializing.
+		Scott was putting expect in the background which disassociated
+		it from a tty, and I was blindly copying the tty parameters
+		without checking to see if they were meaningful or not.
+
+		Tightened up exit code.  Fixed bug in spawn so it would print
+		error messages when it failed.  Spawn sends back the error
+		message in the pty, if the fork succeeds but exec fails.  Cute!
+
+		Added "close" command.  Makes scripts much shorter and cleaner.
+
+		Return string matched by expect directly, rather than setting a
+		special variable.
+
+		Added "match_max" feature.  Probably no one will ever use it.
+
+		Added trace command.
+
+3/6/90	1.4	Rob Densock was the second user, and suggested (demanded?) the
+		idea of the loguser command.  I added it and changed "log" to
+		"logfile" making the first incompatibility with existing
+		scripts (sorry, Steve).
+
+3/1/90	1.3	Trying to make pty code more robust.  Many questions unanswered
+		by manuals.  Did a lot of guessing.  While debugging, looked
+		through pty code in gnuemacs to see if I might increase
+		portability somehow.  Found lots of funky ifdefs on weird
+		ioctls.  Found lots of comments like "this might work".
+
+2/28/90		Sent a short Tcl bug list to John Ousterhout.  He thanked me!
+
+2/22-3/90 1.2	Hooked my first user, Steve Ray.  Surprisingly, he only	found
+		one bug in the code (exit didn't handle args correctly), but it
+		was obvious that I need to put more explanation in the man
+		page.  Many of the examples in the man page are based upon his
+		probl..  questions.  Thanks, Steve!
+
+2/20/90		Posted news about expect to "general" newsgroup locally.
+
+2/15-20/90	Talked to local POSIX reps and then to Steve Albert (AT&T)
+		about portability of select, wait and other system calls.  I'm
+		not impressed by 1003.1.
+
+2/9/90		John Ousterhout answered some questions I had about Tcl	syntax.
+		I like this language!
+
+2/8/90	1.1	Sandy Ressler suggested the idea of being able to spawn
+		multiple programs at the same time although he didn't say how.
+
+		It took about a day to design and code the spawn_id hook.
+		Extremely difficult to support this with uucp-style kludge.
+		Switched to using select.  So much for portability.
+
+		I investigated how to do this portably, and spent some time
+		talking to NIST & AT&T POSIX representatives.  Unfortunately,
+		portability (especially when it comes to select()) remains a
+		dream.  Provided multiple versions of "interact" depending upon
+		what OS you are running.
+
+2/7/90	1.0	Completed first cut of "sex" (for "Smart EXec" or
+		"Send/EXpect").  Supports send, expect, echo, log, spawn,
+		interact.
+
+		Spent a lot of time making "log" write to log in just the right
+		order (across fork and while debug flag enabled).  Ended up
+		writing a bunch of variadic log routines.
+
+		Fooled around with uucp-style multiple processes versus one
+		process doing select() to read asynchronously.  Using
+		uucp-style for now, since it is more portable.
+
+		Gave up on pipes, and switched to ptys.  Pipes seem to be
+		messed up by ftp, perhaps because it goes into raw mode?  Ptys
+		are more efficient and cleaner to program albeit less
+		well-documented and portable from system to system.
+
+		Ken Manheimer helped me explain what the program does.  I kept
+		saying it does "send/expect" processing, and he kept insisting
+		that was meaningless to everyone.  (In fact, it comes from
+		uucp, and I guess uucp hackers are indeed a dying breed.)  Ken
+		gave me an elegant enough sentence that I expanded it into an
+		abstract and sent it in to the USENIX conference the following
+		day (two days after the deadline).
+
+		I noted that the uucp documentation I referenced in the
+		submission is dated October 31, 1978!
+
+1/30/90	0.0	Got a copy of Tcl and went to work.  Tcl was exactly what I
+		need.  Plus, it is easy to use, AND it is documented.
+
+1/25/90		Attended Winter 1990 USENIX in DC, with the goal of banging
+		heads with some other gurus in hopes of finding a good
+		send/expect language for a generalized stelnet.  Had looked at
+		uucp and kermit but found nothing general enough.
+
+		Listened to John Ousterhout's presentation on Tcl.  By the
+		middle of the talk, I had found religion.  At the end when he
+		said it was public-domain, I was ready to swoon.
+
+*/*/88-89	Spent a lot of time telling Scott how useful his program could
+		be if he made it more general.  I thought it wouldn't be that
+		difficult to make more generic.  Scott was interested but not
+		enough to do it.
+
+9/25/87 	Helped Scott Paisley write a program called stelnet, that
+		forked a telnet and did very simple send/expect processing.
+		It used pipes, not ptys.  It had no pattern matching, and only
+		straight-line control without error handling.  Nonetheless,
+		this got me to thinking about making stelnet more generic.

+This file is INSTALL.  It contains installation instructions for Expect.
+
+If you do not have Tcl, get it (Expect's README explains how) and
+install it.  The rest of these instructions assume that you have Tcl
+installed.
+
+If you are installing Expect on a single architecture, or are just
+trying it out to see whether it is worth installing, follow the
+"Simple Installation" below.  If you are installing Expect on multiple
+architectures or the "Simple Installation" instructions are not
+sufficient, see "Sophisticated Installations" below.
+
+--------------------
+Permissions
+--------------------
+
+On a Cray, you must be root to compile Expect.  See the FAQ for why
+this is.
+
+If you want shared libs on Linux, you must be root in order to run
+ldconfig.  See the ldconfig man page for more info.
+
+--------------------
+Simple Installation
+--------------------
+
+By default, the Tcl source directory is assumed to be in the same
+directory as the Expect source directory.  For example, in this
+listing, Expect and Tcl are both stored in /usr/local/src:
+
+	/usr/local/src/tcl8.0		(actual version may be different)
+	/usr/local/src/expect-5.24	(actual version may be different)
+
+If Tcl is stored elsewhere, the easiest way to deal with this is to
+create a symbolic link to its real directory.  For example, from the
+Expect directory, type:
+
+	ln -s /some/where/else/src/tcl8.0 ..
+
+The same applies for Tk, if you have it.  (Tk is optional.)
+
+Run "./configure".  This will generate a Makefile (from a prototype
+called "Makefile.in") appropriate to your system.  (This step must be
+done in the foreground because configure performs various tests on
+your controlling tty.  If you want to do this step in the background
+in the future, automate it using Expect!)
+
+Most people will not need to make any changes to the generated
+Makefile and can go on to the next step.  If you want though, you can
+edit the Makefile and change any definitions as appropriate for your
+site.  All the definitions you are likely to want to change are
+clearly identified and described at the beginning of the file.
+
+To build only the stand-alone Expect program, run "make expect".  This
+is appropriate even if you still haven't decided whether to install
+Expect, are still curious about it, and want to do the minimum
+possible in order to experiment with it.
+
+To build everything, run "make".  If "configure" found Tk and X on
+your system, this will build "expectk" (Expect with Tk).
+
+Once expect is built, you can cd to the example directory and try out
+some of the examples (see the README file in the example directory).
+Note that if Tcl has not yet been installed, this won't work.  In this
+case, see the instructions "Trying Expect Without Installing Tcl"
+below.
+
+"make install" will install Expect.  If you built Expectk, that will
+be installed as well.  So will the documentation and some of the most
+useful examples.
+
+If you want shared libs on Linux, you must now su to root and run
+ldconfig on the shared library.  See the ldconfig man page for more
+info.
+
+A handful of people running "pure" 4.2BSD systems have noted that
+expect fails to link due to lack of getopt and vprintf.  You can get
+these from uunet or any good archive site.
+
+--------------------
+Trying Expect Without Installing Tcl
+--------------------
+
+Once expect is built, you can try it out.  If Tcl has not been
+installed (but it has been compiled), you will need to define the
+environment variable TCL_LIBRARY.  It should name the directory
+contain the Tcl libraries.  For example, if you are using csh with Tcl
+8.0.3:
+
+	$ setenv TCL_LIBRARY ../tcl8.0.3/library
+
+Now you can run expect.
+
+The same advice applies to Tk.  If it is available but has not been
+installed, you can try out expectk but only after defining TK_LIBRARY.
+For example, if you are using csh with Tk 8.0.3:
+
+	$ setenv TK_LIBRARY ../tk8.0.3/library
+
+Now you can run expectk.
+
+--------------------
+Sophisticated Installations
+--------------------
+
+The following instructions provide some suggestions for handling
+complex installations.
+
+--------------------
+Changing Defaults
+--------------------
+
+The configure script allows you to customize the Expect configuration
+for your site; for details on how you can do this, type "./configure
+-help" or refer to the autoconf documentation (not included here).
+Expect's configure supports the following flags in addition to the
+standard ones:
+
+	--verbose		Cause configure to describe
+				what it is checking and what it decides.
+
+	--enable-shared		Compile Expect as a shared library if it
+				can figure out how to do that on this
+				platform.  (You must have already
+				compiled Tcl with this flag.)
+
+	--disable-load		This switch is ignored so that you can
+				configure Expect with the same configure
+				command as Tcl.  If you want to disable
+				dynamic loading, configure Tcl with this
+				flag and then reconfigure Expect.
+
+	--enable-gcc		This switch is ignored so that you can
+				configure Expect with the same configure
+				command as Tcl.  If you want to enable gcc,
+				configure Tcl with it and then reconfigure
+				Expect.  Expect will inherit the definition
+				that way.  It is not safe to modify the
+				Makefile to use gcc by hand.  If you do
+				this, then information related to dynamic
+				linking will be incorrect.
+
+	--enable-threads	This switch is ignored so that you can
+				configure Expect with the same configure
+				command as Tcl.
+
+	--with-tcl=...		Specifies the directory containing Tcl's
+				configure file (tclConfig.sh).
+
+	--with-tclinclude=...	Specifies the directory containing Tcl's
+				private include files (such as tclInt.h)
+
+	--with-tk=...		Specifies the directory containing Tk's
+				configure file (tkConfig.sh).
+
+	--with-tkinclude=...	Specifies the directory containing Tk's
+				private include files (such as tkInt.h)
+
+Some of the defaults in "configure" can be overridden by environment
+variables.  This is a convenience intended for environments that are
+likely to affect any program that you configure and install.
+
+The following environment variables are supported.  If you use these,
+consider adding them to your .login file so that other installation
+scripts can make use of them.
+
+CC		C compiler
+CFLAGS		Flags to C compiler
+CPPFLAGS	Flags to C preprocessor
+LDFLAGS		Flags to linker
+LIBS		Libraries
+CONFIG_SHELL	Shell for configure and Make
+
+Settings can also be given on the command line.  For example, you
+could tell configure about flags from a Bourne-compatible shell as
+follows:
+
+     CFLAGS=-O2 LIBS=-lposix ./configure
+
+Although configure will do some searching for Tcl (and all of this
+discussion holds true for Tk as well), configure likes to find the Tcl
+source directory in the parent directory of Expect and will use that
+Tcl if it exists.  To make sure Tcl can be found this way (if it is
+located somewhere else), create a symbolic link in Expect's parent
+directory to where the Tcl directory is.
+
+By default, configure uses the latest Tcl it can find.  You can
+override this by creating a symbolic link of "tcl" which points to the
+release you want.
+
+If you can't or don't want to create symbolic links, you can instead
+indicate where Tcl and Tk are by using the following environment variables:
+ 
+with_tcl		Directory containing Tcl configure file (tclConfig.h)
+with_tclinclude		Directory containing Tcl include files
+with_tkinclude		Directory containing Tk include files
+with_tk			Directory containing Tk binary library (tkConfig.h)
+
+--------------------
+Multiple-Architecture Installation
+--------------------
+
+You might want to compile a software package in a different directory
+from the one that contains the source code.  Doing this allows you to
+compile the package for several architectures simultaneously from the
+same copy of the source code and keep multiple sets of object files on
+disk.
+
+To compile the package in a different directory from the one
+containing the source code, you must use a version of make that
+supports the VPATH variable.  GNU make and most other recent make
+programs can do this.
+
+cd to the directory where you want the object files and executables to
+go and run configure.  configure automatically checks for the source
+code in the directory that configure is in and in ..  If configure
+reports that it cannot find the source code, run configure with the
+option --srcdir=dir, where dir is the directory that contains the
+source code.
+
+You can save some disk space by installing architecture-independent
+files (e.g., scripts, include files) in a different place than
+architecture-dependent files (e.g., binaries, libraries).  To do this,
+edit the Makefile after configure builds it, or have configure create
+the Makefile with the right definitions in the first place.  To have
+configure do it, use the following options to configure:
+
+	--prefix=indep
+	--exec-prefix=dep
+
+where dep is the root of the tree in which to store
+architecture-dependent files and indep is the root in which to
+store -dependent files.  For example, you might invoke configure this
+way:
+
+	configure --prefix=/usr/local/bin --exec-prefix=/usr/local/bin/arch
+
+--------------------
+Test Suite
+--------------------
+
+Patterned after the Tcl test suite, I have begun building a test suite
+in the subdirectory "test".  It is still incomplete however you may
+use by typing "make test" in this directory.  You should then see a
+printout of the test files processed.  If any errors occur, you'll see
+a much more substantial printout for each error.  See the README file
+in the "tests" directory for more information on the test suite.
+
+Note that the test suite assumes the existence of certain programs to
+use as interactive programs.  If you are missing these or they behave
+differently, errors may be reported.  Similarly, the test suite
+assumes certain other things about your system, such as the sane stty
+parameters.
+
+You may also try some of the programs distribute in the example
+directory (see the README file in the example directory).  They are a
+strong indication of whether Expect works or not.  If you have any
+problems with them, let me know.
+
+--------------------
+Uninstalling
+--------------------
+
+"make uninstall" removes all the files that "make install" creates
+(excluding those in the current directory).
+
+--------------------
+Cleaning Up
+--------------------
+
+Several "clean" targets are available to reduce space consumption of
+the Expect source.  The two most useful are as follows:
+
+"make clean" deletes all files from the current directory that were
+created by "make"
+
+"make distclean" is like "make clean", but it also deletes files
+created by "configure"
+
+Other targets can be found in the Makefile.  They follow the GNU
+Makefile conventions.

+
+** SUMMARY
+
+Expect 5.32 is being released in conjuction with Tcl 8.3.2.
+This is a fairly minor update with no feature changes but with
+a number of useful bug fixes in the way expects uses the new
+regular expression engine and the UTF-8 features of Tcl.
+Details are in the HISTORY and ChangeLog files.
+
+======================================================================
+======================================================================
+
+Date: 10/22/99
+
+** SUMMARY
+
+Expect 5.31 now works with Tcl 8.2.  Expect 5.31 does NOT work with
+prior releases of Tcl.  Thanks to an incredible amount of work by
+Scott Stanton, Henry Spencer, Melissa Hirschl, and funding from
+Scriptics for making this possible.
+
+** NEW FEATURES
+
+What?  You mean that working with Tcl 8.2 isn't enough?????
+
+Expect supports Tcl's new regexp engine.
+
+Expect supports null bytes in strings directly.  (You no longer have
+to use the "null" keyword to send or match nulls.  Of course, the
+"null" keyword will continue to be supported.)  Null removal (on
+input) is still enabled by default since nulls are almost never
+intended for end-user consumption in interactive dialogues.
+
+** CHANGES IN BEHAVIOR (POTENTIAL INCOMPATIBILITIES)
+
+The interpreter command used to exit upon eof.  Now it uses "-eof
+script" to control this behavior.  The default behavior is to return.
+(This change was required because Expect now gives control to Tcl upon
+exit and Tcl waits (potentially forever) for all processes to die on
+exit.)  Explicit calls to interpreter are almost non-existent.
+However, you should look for *implicit* calls via interact commands
+with a pattern but no action.  This required changes in the examples:
+dislocate, dvorak, kibitz, and xkibitz.
+
+Indirect variables can no longer start with "exp".  Such variables
+will be interpreted as channel names.
+
+Old-style regexps may need conversion.  If you have been protecting
+regexps containing backslashes with {}, then you need to examine all
+your backslashes since the new regexp engine interprets backslash
+sequences (such as \n) itself.  For example:
+
+	expect "\n"         (works the same in Tcl 8.0 and 8.1)
+	expect {\n}         (works differently in Tcl 8.0 and 8.1)
+
+Scriptics has also created a new-regexp-features page which you should
+read: http://www.scriptics.com/support/howto/regexp81.html.  Some of
+the new features allow much more efficient regexps than before.  For
+example, non-greedy quantifiers can replace split looping
+constructions with a single regexp, enabling Tcl to parse very
+efficiently.  For the whole story, read the re_syntax man page.
+
+The interact command's regexp matching no longer skips nulls.  (I'd be
+surprised if anyone misses this.  At least I hope ....)
+
+Expect's C library now reports failures in spawn's underlying exec
+directly (by returning -1) rather than the way it used to (as data in
+the pty).  This makes user code more robust.  However, it requires you
+to simplify your code, alas.  See the chesslib.c example.
+
+Linking with Expect's C library no longer requires the Tcl library
+(unless, of course, you make Tcl calls yourself).  Tcl is still
+required to build the library in the first place, however.
+
+** CHANGES IN BEHAVIOR (SHOULD NOT CAUSE INCOMPATIBILITIES)
+
+The match_max command now controls by bytes, not chars.  This won't
+cause problems unless your existing scripts are interacting using
+sizeable chunks of multibyte characters.  (If you don't know what I'm
+talking about, ignore this.)
+
+The Make/configure suite now corresponds to the TEA conventions (at
+least in theory; the conventions are changing regularly so it's hard
+to be less vague on this point).  Significantly, this means that you
+should be able to use the same configure flags as when compiling Tcl
+or any other TEA-compatible extension.  (See the INSTALL file.)
+
+The values of special variables such as exp_spawn_id_any have changed.
+(The values were never documented so you shouldn't have been using
+them anyway.)
+
+Spawn ids now appear as "exp...".  (They used to be small integers.)
+Do not assume that spawn ids will continue to be represented in any
+particular way (other than unique strings).
+
+** OTHER NOTES
+
+Expect uses channels.  There is an Expect channel type.  It is
+possible to use Tcl's channel commands, such as fconfigure, to change
+the encoding.  However, Expect layers its own buffering system on top
+of Tcl's channel handler so don't expect intuitive behavior when using
+commands such as gets and puts.  Unless you know what you're doing, I
+recommend manipulating the Expect channels only with the expect
+commands.
+
+Some effort was made to make Expect support threads, however it is not
+complete.  You can compile Expect with threads enabled but don't run
+Expect in multiple threads just yet.
+
+So much code has changed, there are bound to be bugs in dark corners.
+Please let me know of such cases.  The best response will come by
+supplying a simple test case that can be added to Expect's test suite.
+
+In places where the behavior of Expect was not precisely documented,
+full advantage was taken to do something different :-)
+
+Several esoteric bugs were fixed.
+
+Although Expect itself uses Henry Spencer's new regexp engine,
+Expect's C library still uses his original regexp engine.
+
+No testing has been done of the poll and non-event subsystems.  (These
+are used on systems which don't support select on ptys or ttys.  Some
+minor work needs to be done on them (because the event subsystem was
+rewritten) which I'll probably do only if anyone requests it.
+
+Many deprecated features (deprecated for many years!) have been
+removed.  All such features were deprecated prior to Exploring Expect
+so if that's how you learned Expect, you have nothing to worry about.
+For example, Expect's getpid command predates Tcl's pid command and
+it's been deprecated for, oh.... 6 years - wow!  Other deprecated features
+include:
+  expect -timestamp (flag only; behavior itself was removed years ago)
+  expect -iwrite (flag only; behavior occurs all the time)
+  expect_version (use "exp_version" command)
+  expect_library (use "exp_library" global variable)
+  interact -eof (use "eof" keyword)
+  interact -timeout (use "timeout" keyword)
+  interact -timestamp (use "clock" command)
+  getpid (use "pid" command)
+  system stty (use "stty" command)
+
+With this release, the following are deprecated:
+  timestamp (use "clock" command)
+  debugger (use a different one; there are very nice replacements
+     around.  Fortunately the Expect debugger is not something anyone
+     is wiring into their scripts, so for now, consider it on the
+     endangered species list.  Anyone still want this debugger?)
+
+From now on, the most current snapshots of Expect will be found in the
+Scriptics CVS repository.  Not all snapshots are official releases.

+
+Expect now works with Tcl 8.0.
+
+No changes were made to take advantage of 8.0 features such as
+namespaces.  (If you want to put the Expect commands in a namespace,
+declare a namespace before loading them in.)
+
+Even though Tcl allows embedded nulls in commands, Expect still does
+not.  Tcl still doesn't support embedded in patterns and regexps.
+I'll wait til Tcl supports that before rewriting Expect's null
+support.

+FAQ:       http://expect.nist.gov/FAQ.html
+
+
+
+======================================================================
+======================================================================
+This section describes the changes to Expect 5, many due to changes
+from Tcl 7.4 to 7.5.
+
+Improvements
+==============================
+
+You can now use expect_background from Tcl along with all the
+Tcl-based event stuff such as "after".  You can also do fun things
+such as have "after" actions run while expect is waiting for input.
+It's worth comparing the difference between commands such as expect
+(which waits in the event loop) and gets (which doesn't).
+
+Incompatibilities
+==============================
+
+libexpectk is gone.  Because of the event loop was moved into Tcl,
+this is no longer necessary.  Just use the regular Expect library.
+This only affects you if are hand-linking.
+
+The name of the static C library now has the extension on the end -
+just like Tcl.  This only affects you if are hand-linking.
+
+
+==============================
+Some obvious questions and answers
+
+Nothing in the user interface has changed.  All your old scripts
+should run.  Tcl now has commands that replace Expect functionality in
+the area of version control and date handling.  I encourage you to use
+Tcl's support rather than Expect's for any new scripts that you write.
+However, I won't be removing Expect's commands, so don't worry about
+having to convert old scripts.
+
+It is my understand that shared/dl libs work.  (I say "it is my
+understanding", because my own environment doesn't handle it, sigh.
+My system admins tell me that they're working on it.)  So I've had to
+guess on some things - in fact, I've talked to a number of people and
+I get the feeling that a lot of people are guessing on shared/dl libs.
+I have yet to talk to anyone that REALLY understands this stuff (by
+"understand", I mean "can write the configure/Makefile portably and
+correctly".  So much for my griping.  In theory, the shared/dl support
+is pretty much a freebie because Tcl itself provides all the support
+for this.  (There is some reorganization that could be done to improve
+shared library memory use - I'll get to it eventually - it shouldn't
+affect most people.)  Don't send me complaints about shared/dl libs
+unless you are *positive* it is something that I am responsible for.
+Even if Tcl works and Expect fails, it is likely to be a Tcl error (or
+more precisely, a configuration problem that is more appropriately
+fixed from the Tcl distribution).
+
+For Tcl-package purposes, Expect is called "Expect".  (Duh...)
+
+Expect's multiple interpreter support is minimal.  It should work for
+most things, serendipitously.  I haven't spent any time making this
+perfect.
+
+No, this release isn't portable to Windows or Mac.  Let me know if
+you're seriously interested in a lot of work.  I'm not saying it's not
+possible.  It's definitely possible and the porting working at Sun has
+made it easier than before.  But it's still not a weekend hack.
+
+==============================
+Building the code
+==============================
+
+Expect builds as usual.  (See the INSTALL file for details.)
+
+The only significant change is that Expect now has to find the
+tclConfig.sh file (and tkConfig.sh if you want).  So if you like to
+store Tcl where Expect can't find it, you'll need to use even more
+configure flags than you used to.
+
+Shared/dl Expect libraries are built if you configured Tcl for
+shared/dl libraries.
+
+All support for earlier versions of Tcl and Tk have been removed from
+Expect.  For example, if you're still using Tcl 7.4 (or earlier),
+don't bother to install this release.
+
+======================================================================
+======================================================================
+This section describes the changes from Expect 4 to Expect 5.
+
+The changes that people will find most interesting or annoying are as
+follows.  Some of them may seem rather arbitrary but fix inconsistencies
+leading to much cleaner coding both internally and externally.
+
+
+-- Expect version 5.20 and above is designed to work with Tcl 7.5 and
+Tk 4.1.  Expect 5.20 and above will not work with earlier versions.
+
+-- Glob-style patterns do longest-possible matches (from the earliest
+possible position) just like regexps.  Previously, they matched the
+shortest-possible strings.  However, the documentation didn't actually
+say this (it didn't say anything)
+
+-- Exact patterns are now supported from expect.  Use the "-ex" flag.
+Exact patterns work just like those in interact.  No special handling
+is made of *, ^, etc.
+
+-- The new command "expect_background" registers patterns that are to
+be tested against spawned process output whenever it appears (i.e.,
+asynchronously).  This only works in the Tk environment.  The
+arguments are the same as the expect command.
+
+-- expect_before and expect_after now handle their arguments like
+expect_background.  Previously, a command such as "expect_before"
+with no arguments deleted patterns for all spawn ids.  Now, it only
+deletes patterns for the current spawn id.  Similarly with the "-i"
+form.
+
+-- expect_background/before/after support an -info flag to query what
+the current patterns are.  The results are returned in such a way that
+they can be re-used by a new expect command.
+
+The -info flag must be the first flag in the command.  With no other
+arguments, it returns the setting for the current spawn id.  With a -i
+descriptor, information is returned for that spawn id.  The argument
+-noindirect may be used to suppress indirects which also match a
+direct spawn id.  Only a single -i specification may be given with
+-info.  With the argument "-all", all spawn id specifications are
+reported.
+
+-- There is now a sleep command.  It understands decimal values such as
+
+	sleep .5
+
+Interrupts and other asynchronous events are processed while Expect sleeps.
+
+-- Traps now use Tcl's "Async" support.  This has advantages and
+disadvantages.  One advantage is that traps have no chance of screwing
+up the Tcl internals.  One disadvantage is that trap handlers are
+delayed at certain specific times and places.  For example, a handler
+cannot occur inside another handler.  While one handler is running,
+all other handlers are blocked.  This is probably the most noticable
+place where handlers are blocked.  Others are generally small windows,
+so you shouldn't notice the delay in executing the handlers.
+
+Several traps are initially defined:
+
+	trap exit {SIGINT SIGTERM}
+
+If you use the -D flag to start the debugger, the following trap is
+defined:
+
+	trap {exp_debug 1} SIGINT
+
+You can, of course, override these.  In particular, if you have your
+own "trap exit SIGINT", this will override the debugger trap.  Because
+SIGINT is tied to exit (see above) by default anyway, you should
+remove your own "trap exit SIGINT" unless you specifically do not want
+to be able to get to the debugger by ^C.
+
+If you want to define your own trap on SIGINT but still trap to the
+debugger when it is running, use:
+
+	if !exp_debug {trap mystuff SIGINT}
+
+Alternatively, you can trap to the debugger using some other signal.
+
+The ONEXIT trap is no longer available.  Instead, say "exit -onexit ..."
+
+Traps are now deleted by using the empty ({}) handler.  The current
+handler is returned if no action is supplied.  With no arguments, trap
+returns the signal number of the trap command currently being executed.
+
+-- The wait command now returns a four element list if a valid child
+was waited on.
+Element 1: pid
+Element 2: spawn id
+Element 3: 0 (or -1 if there was an OS error)
+Element 4: status (or errno if element 3 == -1)
+
+-- expect and interact notes:
+
+The timeout and eof patterns were initially named "-timeout" and
+"-eof" but have been renamed "timeout" and "eof" to match those of
+expect.  The ability to define default timeout/eof actions has been
+removed.  (You can do this more easily by grouping spawn ids.)
+
+expect and interact now support a "null" keyword to match an ASCII 0.
+send supports -null and -break keywords.
+
+Since a large number of special keywords have been added to interact,
+a new keyword "-ex" for "exact" was added descriptive of its default
+treatment of patterns.  This protects the next token from being
+misinterpreted as a keyword.  The expect command provides "-gl" for
+"glob" for analogous reasons.
+
+Any string starting with "-" should be protected by the "-ex" or "-gl"
+flag, even those that are not keywords currently.  (All strings
+starting with "-" are reserved for future options.)
+
+String start/end indices are no longer written to expect_out and
+interact_out unless the -indices flag is given.
+
+expect_out(spawn_id) is set to the spawn id associated with the spawn
+id that produced the last output in an expect command.  For example,
+you can use this to delete files that have closed, by removing this
+element from an indirect spawn ids spec.  The same effect is
+reproducable with interact (and interact_out(spawn_id)) but for
+efficiency reasons, it requires the -iwrite flag before each pattern.
+
+Expect's -i and interact's -i, -u, -input, and -output flags can now
+describe a list of spawn ids.  So you can say things like:
+
+	interact -input "$id1 $id2 $id3" .... -output "$id1 $id2" ...
+
+In this case, id1, 2, 3 would be sent to id1, and 2.
+
+The spawn id may be given as a global variable name (called an
+"indirect spawn id specification"), in which case, the variable
+contains the list of spawn ids.  Whenever the variable is changed, the
+new list of spawn ids is automatically used.  This is particularly
+useful with any long running expect command such as expect_before,
+expect_after, expect_background, and interact.
+
+The -update flag was removed.  Use indirect spawn ids (see previous
+paragraph).
+
+-- interact notes:
+
+Interact now support -input and -output flags that provide very
+flexible means of moving data from/to multiple spawn ids in complex
+ways (but very quickly).  It is possible to write most expect loops
+using a simple interact statement.  For instance, the three way
+interaction inside kibitz (between two users and a process) is written
+this way:
+
+	interact {
+		-output $shell
+		-input $userin eof { . . . } -output $shell
+		-input $shell -output "$user_spawn_id $userout"
+	}
+
+-- send command notes:
+
+It is possible to send a break by using the "-break" flag.
+
+Any string starting with "-" should be protected by preceding it with
+the "--" flag, even those that are not keywords currently.  (All
+strings starting "-" are reserved for future options.)
+
+-- The spawn command now takes an "-open" flag which in turns takes a
+Tcl file as an argument.  This lets you treat raw devices, files, and
+pipelines as spawned processes without using a pty.
+
+This was actually in Expect 4, but I forgot to document it.  Oops!
+
+-- The old "debug" command (which describes what Expect is doing
+internally) was renamed "exp_internal".  "debug" (and "exp_debug") now
+invoke the interactive debugger.
+
+-- The new command "stty" now takes over the job of "system stty".  It
+works much better, allowing POSIX-style redirection to affect other
+ttys.  It otherwise takes arguments as "system stty" did.
+
+-- The "-tcl" option to "return" has gone away.  (This was dangerous
+to anyone that actually happened to return the value "-tcl".)
+Instead, use inter_return.
+
+-- Added exp_timestamp command to produce very fast timestamps.
+
+-- Added exp_pid command to return pid of given spawn id.
+
+-- The close command now takes an argument of "-onexec" with a following
+0 or non-zero value.  For example, the follow command stops the
+current spawn id from being closed when another process is exec'd or
+spawn'd.
+
+	close -onexec 0
+
+While "-onexec 1" returns it to the default condition where it will be
+closed upon exec or spawn.
+
+-- log_user now returns previous value.  It is acceptable to call now,
+without arguments just to get the value.
+
+-- The following forms are deprecated.  They will be allowed
+indefinitely but not advertised or supported if they break.
+
+	-eof, -timeout in interact (reason: didn't match expect.
+		Instead, use eof or timeout.)
+
+	-- in expect or interact (reason: no easier to read.
+		Instead, use -gl in expect or -ex in interact.)
+
+	continue -expect (reason: when mixing in extensions, you have
+		to use exp_continue, so -expect becomes irrelevant.
+		Instead, use exp_continue.)
+
+	getpid (reason: Tcl now supplies same functionality as "pid".
+		Instead, use pid.)
+
+	expect_version and expect_library (reason: the name implies
+		they have something to do with the expect command,
+		which they doesn't.
+		Instead, use exp_version and exp_library.)
+
+	-timestamp for obtaining tm and ctime in expect and interact
+		(reason: separate command now exists for this purpose.
+		Instead, use exp_timestamp.)
+
+	system stty (reason: bad interaction with redirection.
+		Instead, use stty.)
+
+-- New examples have been added:
+
+"dislocate" lets you disconnect and reconnect to processes.
+
+"tkpasswd" illustrates passwd embedded in a GUI.
+
+They may not be overwhelmingly useful, but run them once to see what
+they do.  If you ever need to do anything similar, you can look back
+at them.
+
+"tknewsbiff" pops up a window or plays a audio clip when you have
+unread news.
+
+-- Changes to the Expect libraries:
+
+The expect-tcl library (libexpectcl.a) has been integrated with the
+expect library (libexpect.a).  So references to libexpectcl.a should
+be removed.
+
+The Expect C library now supports buffering, multiplexing, null
+matching, full buffer matching.  Basically, all of the features in
+Expect are now in the library.
+
+Buffering and multiplexing has caused the biggest change to the
+library.  Previously, exp_match contained the entire buffer that
+matched.  Now exp_match just points to where in the buffer the match
+started.  exp_buffer points to the beginning of the buffer.
+Previously, the previous buffer was thrown away at the beginning of
+each expect function call.  Now, previously unmatched characters are
+eligible for matching.
+
+To match on different file descriptors, exp_match, exp_match_end,
+exp_buffer_end must be restored to their previous values.  Initially,
+they should be zero.
+
+The meaning of timeout == 0 in the Expect library has been changed.
+See the man page for more info.
+
+======================================================================
+======================================================================
+This file describes the changes from Expect 3 to Expect 4.
+
+The improvements that people will find most interesting are:
+
+1) Expect version 4 is designed to work with Tcl 6.7 and Tk 3.2.
+   (Earlier versions of Expect will not work with Tcl 6.7)
+   Expect can now be layered in with any Tcl program.  
+   Note that in Tk, Expect's send command is called "exp_send".
+   (It used to be called "send_spawn" but this bit the dust.)
+2) A debugger is provided.
+3) The interact command has been totally rewritten and supports regular
+   expressions, timeout/eof patterns, and a number of other new things.
+4) The default behavior of ^C (SIGINT) is exit whether or not you are in
+   a read.
+5) Expect uses "sane" terminal parameters by default, allowing scripts
+   to work the same whether inside emacs shell mode or not.  (See man
+   page on "spawn" for more info.)
+6) All the hard parts of the installation process are automated.  This
+   was done primarily by Rob Savoye at Cygnus.  Thank you, Rob!
+7) It is now possible to buy a support contract for Expect from Cygnus.
+
+The changes that people will find most annoying are:
+
+1) send now only sends a single string.  (It used to send any number of
+   strings with spaces jammed in between.)
+2) getpid was renamed pid.
+3) interact's -flush was renamed -nobuffer (much more descriptive).
+4) interact now runs all actions in raw mode unless the flag -reset
+   is used.  -f and -F are ignored.  send automatically understands
+   how to do the right thing.  The most likely thing to watch out for
+   are actions like "exec kill -STOP 0" which almost certainly need
+   the -reset flag.
+5) argv0 is initialized to script name.  argv no longer contains it.
+   argc is initialized llength $argv.  This follows new Tcl style.
+
+All differences are described in the man page.  Some of the less
+significant differences are described in the HISTORY file.  The
+debugger is described in a separate document (see the README).
+
+This version also introduces one incompatibility that may require
+changes to scripts.  While this may initially annoy you, the final
+result will simplify the process of writing scripts.  Namely:
+
+In version 3, the expect command accepted lists of glob-style patterns
+such as:
+
+	expect "a\ b c" action
+
+where "a b" or "c" would cause action to be executed.  The problem
+with this is that the pattern list is hard to write and hard to read.
+Patterns with control-characters, backslashes and dollar signs were
+very difficult to deal with.
+
+Regular-expression patterns provide a much simpler solution.  Via the
+alternation feature (using a "|") the above pattern can be written as:
+
+	expect -re "a b|c" action
+
+I was concerned about people having a significant investment in code
+that depended on the old syntax but responders to a comp.lang.tcl poll
+about such a change in pattern handling were 100% in favor of it.  (I
+even proposed hooks for backward compatibility, but there was no
+interest in it.)
+
+Fortunately, most simple things will work as before including:
+
+	expect foobar
+	expect {foobar}
+	expect "foobar"
+	expect "foo\ bar"
+
+However, some things won't work as before.  For example, the following
+will behave differently - now the braces will be considered as part of
+the pattern.
+
+	expect "{foo bar}"
+
+Here are examples of patterns in my own code that I had to change:
+
+	was				changed to
+	Version 3 pattern list		Version 4 pattern
+
+	{Whois:\ }			"Whois: "
+	{No\ match}			"No match"
+	{250*ftp>* 200*ftp>*}		-re "2(5|0)0.*ftp>.*"
+	{{Press Return to continue*}}	"Press Return to continue*"
+	{*\r\n*\\\\\r\n}		"\r\n*\\\r\n"
+
+
+
+Future Change Alert
+
+John Ousterhout has pre-announced a future change in Tcl that may
+affect you.  In particular, backslash sequences other than those
+explicitly listed in the Tcl documentation will be handled as if the
+backslash was not present.
+
+The likely place this arises is when quoting characters that are
+special to the pattern matcher but not to Tcl.
+
+For example in Tcl 6.7, the following command matches a period.
+
+	expect -re "\."
+
+In Tcl 7.0, it will match any character, because Tcl will throw away
+the backslash.  If you want to match a period, you will have to say:
+
+	expect -re "\\."
+or
+	expect -re {\.}
+
+The following command will find occurrences of this.  (It may find
+other things, but it will at least find the problem cases.)
+
+	egrep '(\\$)|(\\^bfnrtv\0-9{}$ ;")' *.exp
+
+======================================================================
+======================================================================
+This section describes the changes from Expect 2 to Expect 3.
+
+If you used to use Expect version 2 (any version written before
+September '91) you will find that the current version of Expect (3)
+introduced minor but significant incompatibilities.
+
+The HISTORY file describes these briefly.  They are described at
+length in the man page.
+
+I'm sorry if you feel annoyed at the incompatibilities, but Expect has
+been out for a year and a half, Tcl even longer.  Both Tcl and Expect
+are using this as a last chance to make significant changes, so that
+we will not disturb even more users in the future.
+
+There is no automated conversion procedure (although see note below)
+for Expect or even raw Tcl.  For now, I suggest that you not bother
+fixing things that already work - just keep the old Expect around.
+The binary isn't very big after all.  If you do write a translation
+script, let me know.  Thanks.
+
+Of course, I felt obligated to convert the examples distributed with
+expect.  I did this by hand while writing the new version itself,
+partly as an aid but mostly to test lots of variations.  In 90% of the
+scripts, all I had to do was change:
+
+(changes due to Tcl)
+	'index' to 'lindex'
+	'range' to 'lrange'
+	'length' to 'llength'
+	'print' to 'send_user' or 'puts' depending on how you use it
+	'function .... c' with 'join function split string "" ""'
+(changes due to Expect)
+	'expect_match' to 'expect_out(buffer)'
+	'set match_max' to 'match_max' (perhaps with -d flag)
+	'*' to '-re .+'
+
+If anyone wants to write a script to do this, note the pitfalls:
+
+1) functions and variables do not share the same namespace, so it is a
+inappropriate to just globally rename things.
+
+A number of optimizations can be made:
+
+1) If you are doing multiple split/joins, you should probably cache the
+split string.
+
+2) Virtually all uses of scan are unnecessary now, due to exec's automatic
+stripping of terminating newlines, and expect's support of regexps.
+
+3) String manipulation can be reduced or avoided entirely if you use
+expect -re.
+
+4) exec is no longer necessary to retrieve environment variables, since
+they can now be retrieved from $env.
+
+5) If you have been really careful about testing for timeout and eof,
+you can dramatically reduce the size of your scripts by using
+expect_before and expect_after.  This is more efficient, as well,
+since those actions are only parsed once.

+Introduction
+--------------------
+
+This is the README file for Expect, a program that performs programmed
+dialogue with other interactive programs.  It is briefly described by
+its man page, expect(1).  This directory contains the source and man
+page for Expect.
+
+This README file covers Expect 5.38 and up.  These versions of Expect
+work with Tcl 8.2 and up and Tk 8.2 and up.  Significant changes and
+other news can be found in the NEWS file.
+
+The Expect home page is: http://expect.nist.gov
+The Expect FAQ is:       http://expect.nist.gov/FAQ.html
+
+--------------------
+Getting Started - The Preferable Way
+--------------------
+
+A book on Expect is available from O'Reilly with the title "Exploring
+Expect: A Tcl-Based Toolkit for Automating Interactive Applications",
+ISBN 1-56592-090-2.
+
+The book is filled with detailed examples and explanations, and is a
+comprehensive tutorial to Expect.  The book also includes a tutorial
+on Tcl written specifically for Expect users (so you don't have to
+read the Expect papers or the man pages).  Exploring Expect is 602
+pages.
+
+--------------------
+Getting Started - The Hacker Way
+--------------------
+
+While the book is the best way to learn about Expect, it is not
+absolutely necessary.  There are man pages after all and there are
+numerous articles and papers on Expect.  All of my own papers are in
+the public domain and can be received free.  If you are a hacker on a
+tight budget, this may appeal to you.  Nonetheless, I think you will
+find the book pays for itself very quickly.  It is much more readable
+than the man pages, it includes well-written and explained examples,
+and it describes everything in the papers as a coherent whole.  The
+concepts in the papers actually only make up a small fraction of the
+book.
+
+The 1990 USENIX paper (see "Readings" below) is probably the best one
+for understanding Expect conceptually.  The 1991 Computing Systems and
+the LISA IV papers provide a nice mix of examples.  The only downside
+is, the examples in these papers don't actually work anymore - some
+aspects (e.g., syntax) of both Expect and Tcl have changed.  The
+papers still make interesting reading - just don't study the examples
+too closely!  Fortunately, most of the examples from the papers also
+accompany this distribution - and all of these are up to date.
+
+For all the details, read the man page.  It is long but you can get
+started just by skimming the sections on the following commands:
+
+	spawn		(starts a process)
+	send		(sends to a process)
+	expect		(waits for output from a process)
+	interact	(lets you interact with a process)
+
+To print out the Expect man page, invoke your local troff using the
+-man macros, such as either of:
+
+		ptroff -man expect.man
+		ditroff -man expect.man
+
+If Expect is installed, you can read the man pages using the "usual"
+man commands, such as "man expect".  If not installed, view the man
+page on your screen by saying something like:
+
+		nroff -man expect.man | more
+
+Expect uses Tcl as the underlying language for expressing things such
+as procedures, loops, file I/O, and arithmetic expressions.  For many
+simple scripts, it is not necessary to learn about Tcl.  Just by
+studying the examples, you will learn enough Tcl to get by.  But if
+you would like to learn more about Tcl or use it in your own
+applications, read the Tcl README file which provides pointers to the
+extensive Tcl documentation.  Or read Exploring Expect.  Chapter 2 of
+Exploring Expect is a Tcl tutorial specifically designed for Expect
+users.
+
+An interactive debugger is bundled with Expect.  The debugger has its
+own documentation that comes separately.  It is listed in the Readings
+below.  Again, it is slightly out of date.  An up-to-date description
+of the debugger appears in Chapter 18 of Exploring Expect.  This
+chapter also contains additional advice and tips for debugging.
+
+You may get the feeling that the Expect documentation is somewhat
+scattered and disorganized.  This was true prior to publication of
+Exploring Expect.  The book contains everything you need to know, all
+up-to-date, and with examples of every concept.  (The book contains no
+references to any of the Expect papers because none are necessary.)
+
+----------------------
+Examples
+----------------------
+
+This distribution contains many example scripts.  (All of the
+substantive examples in the book are included.)  They can be found in
+the example directory of this distribution.  The README file in that
+directory briefly describes all of the example scripts.  Many of the
+more sophisticated examples have man pages of their own.
+
+Other interesting scripts are available separately in the directory
+http://expect.nist.gov/scripts/ (ftpable as
+ftp://ftp.nist.gov/mel/div826/subject/expect/scripts).  (See below for
+how to retrieve these.)  You are welcome to send me scripts to add to
+this directory.  A number of Expect scripts are also available in the
+Tcl archive, available at ftp://ftp.neosoft.com/pub/tcl.

+How to Get the Latest Version of Expect or the Readings
+--------------------
+
+Expect may be ftp'd as mel/div826/subject/expect/expect.tar.gz from
+expect.nist.gov.  (Yes, the URL is much shorter:
+http://expect.nist.gov/expect.tar.Z) Request email delivery by mailing
+to "library@cme.nist.gov".  The contents of the message should be (no
+subject line) "send pub/expect/expect.tar.Z".
+
+Once you have retrieved the system, read the INSTALL file.  The papers
+mentioned above can be retrieved separately (from the same directories
+listed above) as:
+
+ doc/seminal.ps.Z         (USENIX '90 - Intro and Implementation)
+ doc/sysadm.ps.Z            (LISA '90 - System Administration)
+ doc/scripts.ps.Z  (Comp. Systems '91 - Overview of Scripts)
+ doc/regress.ps.Z         (USENIX '92 - Testing)
+ doc/kibitz.ps.Z            (SP&E '93 - Automating Multiple

+
+The book "Exploring Expect" is described in more detail earlier in
+this file.
+
+The book "Obfuscated C and Other Mysteries" is not on-line but is
+available in bookstores or directly from the publisher (Wiley).
+
+Overhead transparencies I've used at conferences are also available in
+the same way as the papers themselves.  The transparencies are sketchy
+and not meant for personal education - however if you are familiar
+with Expect and just want to give a short talk on it to your
+colleagues, you may find the transparencies useful.  They vary in
+length from 15 to 20 minutes in length.  These are:
+
+  doc/seminal-talk.ps.Z    (USENIX '90 - Intro and Implementation)
+  doc/sysadm-talk.ps.Z       (LISA '90 - System Administration)
+  doc/regress-talk.ps.Z    (USENIX '92 - Testing)
+  doc/tcl-debug-talk.ps.Z  (Tcl/Tk '93 - Tcl/Tk Debugger)
+  doc/expectk-talk.ps.Z (Xhibition '94 - Expect + Tk = Expectk)
+  doc/bgpasswd-talk.ps.Z     (LISA '94 - Passwords in the Background)
+
+All of the documents are compressed PostScript files and should be
+uncompressed and sent to a PostScript printer.  The documents are
+intended for printing at 8.5"x11" and may fail on some ISO A4
+printers.  According to Hans Mayer <Hans.Mayer@gmd.de>, you can make
+them A4-able by searching for "FMVERSION" and changing the next line
+from:
+
+	1 1 0 0 612 792 0 1 13 FMDOCUMENT
+to:
+	1 1 0 0 594 841 0 1 13 FMDOCUMENT

+
+--------------------
+Using Expect with and without Tcl and/or Tk.
+--------------------
+
+The usual way of using Expect is as a standalone program with Tcl as
+the control language.  Since you may already have Tcl, it is available
+separately.  Tcl may be retrieved as tcl.tar.Z in the same way as
+described above for Expect.  When new releases of Tcl appear, I will
+try to check them out for Expect as soon as possible.  If you would
+like to get the newest Tcl release without waiting, ftp it from
+ftp.scriptics.com (directory pub/tcl).
+
+Expect may also be built using the Tk library, a Tcl interface to the
+X Window System.  Tk is available in the same way as Tcl.
+
+It is possible to embed the Expect/Tcl core and optionally Tk in your
+own C programs.  This is described in libexpect(3).
+
+Expect can also be used from a C or C++ program without Tcl.  This is
+described in libexpect(3).  While I consider this library to be easy
+to use, the standalone Expect program is much, much easier to use than
+working with the C compiler and its usual edit, compile, debug cycle.
+Unlike typical programming, most of the debugging isn't getting the C
+compiler to accept your programs - rather, it is getting the dialogue
+correct.  Also, translating scripts from Expect to C is usually not
+necessary.  For example, the speed of interactive dialogues is
+virtually never an issue.  So please try 'expect' first.  It is a more
+appropriate tool than the library for most people.
+
+--------------------
+Systems Supported
+--------------------
+
+I do not know of any UNIX systems on which Expect will not run.
+Systems which do not support select or poll can use Expect, but
+without the ability to run multiple processes simultaneously.  I am
+willing to work with you to complete a port.
+
+Before sending me changes, please download or verify that you have the
+latest version of Expect (see above).  Then send me a "diff -c" along
+with a suitable English explanation.  If your diff involves something
+specific to a machine, give me diffs for configure.in as well or give
+me a hint about when the diffs should be done so I can write the
+configure support myself.  Also please include the version of the OS
+and whether it is beta, current, recent, or totally out-of-date and
+unsupported.
+
+--------------------
+Installing Expect
+--------------------
+
+Expect comes with a configure script that provides for an automated
+installation.  I believe you will find that Expect is very easy to
+install.  (Tcl and Tk, too.)
+
+For more information, read the INSTALL file.
+
+--------------------
+Support from Don Libes or NIST
+--------------------
+
+Although I can't promise anything in the way of support, I'd be
+interested to hear about your experiences using it (good or bad).  I'm
+also interested in hearing bug reports and suggestions for improvement
+even though I can't promise to implement them.
+
+If you send me a bug, fix, or question, include the version of Expect
+(as reported by expect -d), version of Tcl, and name and version of
+the OS that you are using.  Before sending mail, it may be helpful to
+verify that your problem still exists in the latest version.  You can
+check on the current release and whether it addresses your problems by
+retrieving the latest HISTORY file (see "History" above).
+
+
+Awards, love letters, and bug reports may be sent to:

+
+Usage: $0 OPTION... VAR=VALUE...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE disabled
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR configure dir or \`..'
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          PREFIX
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+# references to their dependent libraries, i.e., any additional
+# libraries that must be linked to.  And some systems get upset if the
+# references are repeated on the link line.  So therefore, we create
+# one for Expect, one for Expect and Tcl, and one for building Expect's own
+# shared library.  Tcl's tclConfig.sh insists that any shared libs
+# that it "helps" build must pass the libraries as LIBS (see comment
+# near end of this configure file).  I would do but since we're close
+# to hitting config's max symbols, we take one short cut and pack the
+# LIBS into EXP_SHLIB_LD_LIBS (which is basically what Tcl wants to do
+# for us).  The point, however, is that there's no separate LIBS or
+# EXP_LIBS symbol passed out of configure.  One additional point for
+# confusion is that LIBS is what configure uses to do all library
+# tests, so we have to swap definitions of LIBS periodically.  When we
+# are swapping out the one for Expect's shared library, we save it in
+# EXP_LIBS.  Sigh.

+# An explanation is in order for the strange things going on with the

+# reason is that some systems require shared libraries include
+# references to their dependent libraries, i.e., any additional
+# libraries that must be linked to.  And some systems get upset if the
+# references are repeated on the link line.  So therefore, we create
+# one for Expect, one for Expect and Tcl, and one for building Expect's own
+# shared library.  Tcl's tclConfig.sh insists that any shared libs
+# that it "helps" build must pass the libraries as LIBS (see comment
+# near end of this configure file).  I would do but since we're close
+# to hitting config's max symbols, we take one short cut and pack the
+# LIBS into EXP_SHLIB_LD_LIBS (which is basically what Tcl wants to do
+# for us).  The point, however, is that there's no separate LIBS or
+# EXP_LIBS symbol passed out of configure.  One additional point for
+# confusion is that LIBS is what configure uses to do all library
+# tests, so we have to swap definitions of LIBS periodically.  When we
+# are swapping out the one for Expect's shared library, we save it in

+This file is example/README.  It contains brief descriptions of the
+examples in this directory.  Also listed are scripts from the Expect
+archive at ftp.cme.nist.gov (See Expect's README for how to retrieve
+these from).  You are welcome to send me additional scripts.  A number
+of Expect scripts are also available in the Tcl archive, available via
+anonymous ftp at harbor.ecn.purdue.edu
+
+Note that on some systems, some of the scripts (notably kibitz and
+dislocate) require that Expect be installed.  (Merely compiling the
+expect binary is not enough.)
+
+--------------------
+Expect scripts (See next section for example Tk scripts)
+--------------------
+Entries marked with "m" have their own man page.
+Entries marked with "a" live in the Expect archive (see above).
+
+	archie - mails back response after talking to archie ftp-catalog.
+   m	autoexpect - generate an Expect script from watching a session
+	autopasswd - runs passwd non-interactively for superuser.
+   a	bc - Uses bc to do arbitrary precision math.
+	beer.exp - 99 Bottles of Beer On The Wall, Expect-style.
+	beer.exp.out - sample output from beer.exp (but you really have to
+		run it to see the timing aspect).
+   a	bonfield.exp - solve Jim Bonfield's puzzle that won the 1991 Obfuscated
+		C Code contest.
+	carpal - warn about typing for too long without a break.
+	chess.exp - has two chess games play each other.
+   m	cryptdir - encrypt all files in a directory.
+   m    decryptdir - decrypt all files in a directory.
+   m	dislocate - allow disconnection/reconnection to background processes.
+	dvorak - dvorak keyboard.
+   a	eftp - ftp client with miscellaneous frills (also see rftp below).
+	expectd.proto - telnet daemon.
+	ftp-inband - does file transfer over telnet, rlogin, etc.
+	ftp-rfc - retrieve a DoD RFC from uunet via anonymous ftp.
+	ftp-talk-radio - gets "Internet Talk Radio" files from a host.
+	gethostbyaddr - translates internet address to name (with a higher
+		success rate than nslookup).  Easier to use, too.
+	getpassck - test for presence of bug in getpass.
+	irsh - run interactive commands via rsh
+   m	kibitz - lets two people control a program at the same time.
+		Lots of uses.  I.e., You can help another person remotely.
+		Can run an editor and log a transcript of a conversation.
+   a	libro-II - connect to Libro-II, the NIST library catalog.
+	lpunlock - unhangs a printer which says it is "waiting for lock".
+   a	mirror_file - mirror a file from another ftp site, copying file only
+		if changed.
+   a	mirror_dir - mirror a directory from another ftp site, copying only
+		files which have changed.
+   m	multixterm - drive several xterms simultaneously.
+   m	mkpasswd - generates good passwords, optionally runs passwd with them.
+   a	mx - return any MX records for the given host.
+   a	noidle - run a shell which avoids being 'autologged out'.
+   a	pager.alpha - sends a message to a (Alpha brand) pager.
+   a	pager.mercury - sends a message to a (Mercury brand) pager.
+   m	passmass - sets passwd on many machines simultaneously.
+        passwd.html - form to change a login passwd
+	passwd.cgi - CGI script to respond to passwd.html form
+	passwdprompt - Prompt from stdin and echo *'s.
+   a	ping-and-page - Ping list of hosts.  If any down, page system admin.
+	read1char - read a single character for the shell, Perl, etc.
+	reprompt - like timed-read but reprompt after given amount of time.
+	rlogin-cwd - rlogin giving you same current working directory.
+		(Compare to telnet-cwd and xrlogin.)
+	robohunt - plays the game of hunt (from Berkeley).
+		It's more of a wild player than good, but amusing to watch.
+		Fun to throw against people who don't know about it.
+	rogue.exp - finds a good game of rogue.
+	rftp - recursive ftp (assumes UNIX-style ftpd at other end).
+   a	s-key-rlogin - 	Automate rlogin (or telnet) using s/key
+   a	scripttoggle - Like UNIX script command, but allow enabling/disabling
+		of recording.
+   a	slip.shar - scripts to keep your SLIP link alive.
+	su.exp - start up an 'su' and run the argument.
+	telnet-cwd - telnet giving you same current working directory.
+	telnet-in-bg - put telnet (or any program) in bg, saving all remaining
+		output to a logfile.
+   a	term-rlogin - run Term over rlogin.  Good for traversing PPP/SLIP or
+		firewall rlogin connections.
+   a	term-start - start up Term (a sophisticated UNIX-to-UNIX serial line
+		handler).
+   a	timed-choice - offer user a timed choice of responses.
+	timed-read - a timed read for the shell, Perl, etc.  Compare with
+		reprompt example.
+   m	timed-run - run a program for only a given amount of time.
+   a	try-phone-list - automate logging in to remote system, trying numbers
+		from a list until finding one that works.
+   m	unbuffer - disables output buffering that normally occurs when
+		programs are redirected.
+	virterm - example of terminal emulation and expect operations on
+		character graphics using arrays (compare to term_expect
+		(below) which uses Tk widget).
+	vrfy - verifies an email address using SMTP/VRFY to remote site.
+   a	waste-collection - Contact NIST service for hazardous waste pickup.
+	weather - retrieves weather forecasts.
+   m	xkibitz - similar to kibitz but uses X Window System for handling
+		communication.  Also, allows users to be added dynamically.
+	xrlogin - rlogin giving you same DISPLAY.  (Compare to rlogin-cwd.)
+
+To run, for example, chess.exp, type:
+
+	expect chess.exp
+
+If expect is installed and your system supports the #! magic you can
+invoke it as:
+
+	chess.exp
+
+Each of these examples necessarily depends upon other binaries in the
+system.  For example, chess.exp depends upon the "usual" UNIX chess
+program being present.  If any of these programs are different,
+it may cause the associated script to misbehave.
+
+Please use the ".exp" extension on scripts that might otherwise have
+names that could be confused with the real program, such as "rogue.exp".
+Scripts that have unique names do not need the extension, such as "rftp".
+
+--------------------
+Sample Expectk scripts
+--------------------
+Entries marked with "m" have their own man page.
+
+	term_expect - template for doing expect operations on character
+		graphics.
+   m	tknewsbiff - pops up a window (or plays sounds, etc) when news
+		arrives in selected newsgroups.
+   	tkpasswd - Tk GUI for changing passwords.
+	tkterm - Tk terminal emulator in a Tk text widget.
+	xpstat - provide an X window front end to the xpilot game.
+
+--------------------
+Sample C and C++ programs that use the Expect library
+--------------------
+
+	chesslib.c - same thing as chess.exp, but in C.
+	chesslib2.c - ditto, but uses popen and stream-style I/O.
+	chesslib++.c - ditto, but for C++.
+   m	unbuffer.c - same as unbuffer example but standalone
+
+You may change the value of CC or CPLUSPLUS in the Makefile, to
+compile under gcc or other compilers.  However, you may have to edit
+the lines defining where the libraries are.

+.TH AUTOEXPECT 1 "30 June 1995"
+.SH NAME
+autoexpect \- generate an Expect script from watching a session
+.SH SYNOPSIS
+.B autoexpect
+
+.I args
+
+
+.I program args...
+
+.br
+.SH INTRODUCTION
+
+autoexpect watches you interacting with another program and creates an
+Expect script that reproduces your interactions.  For straightline
+scripts, autoexpect saves substantial time over writing scripts by
+hand.  Even if you are an Expect expert, you will find it convenient
+to use autoexpect to automate the more mindless parts of interactions.
+It is much easier to cut/paste hunks of autoexpect scripts together
+than to write them from scratch.  And if you are a beginner, you may
+be able to get away with learning nothing more about Expect than how
+to call autoexpect.
+
+The simplest way to use autoexpect is to call it from the command line
+with no arguments.  For example:
+
+	% autoexpect
+
+By default, autoexpect spawns a shell for you.  Given a program name
+and arguments, autoexpect spawns that program.  For example:
+
+	% autoexpect ftp ftp.cme.nist.gov
+
+Once your spawned program is running, interact normally.  When you
+have exited the shell (or program that you specified), autoexpect will
+create a new script for you.  By default, autoexpect writes the new
+script to "script.exp".  You can override this with the \-f flag
+followed by a new script name.
+
+The following example runs "ftp ftp.cme.nist.gov" and stores the
+resulting Expect script in the file "nist".
+.nf
+
+	% autoexpect \-f nist ftp ftp.cme.nist.gov
+
+.fi
+It is important to understand that
+autoexpect does not guarantee a working script because it necessarily
+has to guess about certain things \- and occasionally it guesses wrong.
+However, it is usually very easy to identify and fix these problems.
+The typical problems are:
+.RS
+.TP 4
+\(bu
+Timing.  A surprisingly large number of programs (rn, ksh, zsh,
+telnet, etc.) and devices (e.g., modems) ignore keystrokes that arrive
+"too quickly" after prompts.  If you find your new script hanging up
+at one spot, try adding a short sleep just before the previous send.
+
+You can force this behavior throughout by overriding the variable
+"force_conservative" near the beginning of the generated script.  This
+"conservative" mode makes autoexpect automatically pause briefly (one
+tenth of a second) before sending each character.  This pacifies every
+program I know of.
+
+This conservative mode is useful if you just want to quickly reassure
+yourself that the problem is a timing one (or if you really don't care
+about how fast the script runs).  This same mode can be forced before
+script generation by using the \-c flag.
+
+Fortunately, these timing spots are rare.  For example, telnet ignores
+characters only after entering its escape sequence.  Modems only
+ignore characters immediately after connecting to them for the first
+time.  A few programs exhibit this behavior all the time but typically
+have a switch to disable it.  For example, rn's \-T flag disables this
+behavior.
+
+The following example starts autoexpect in conservative
+mode.
+.nf
+
+	autoexpect \-c
+
+.fi
+The \-C flag defines a key to toggle conservative mode.  
+The following example starts autoexpect (in non-conservative
+mode) with ^L as the toggle.  (Note that the ^L is
+entered literally - i.e., enter a real control-L).
+.nf
+
+	autoexpect \-C ^L
+
+.fi
+The following example starts autoexpect in conservative
+mode with ^L as the toggle.
+.nf
+
+	autoexpect \-c \-C ^L
+
+.fi
+.TP
+\(bu
+Echoing.  Many program echo characters.  For example, if you type
+"more" to a shell, what autoexpect actually sees is:
+.nf
+
+	you typed 'm',
+	computer typed 'm',
+	you typed 'o',
+	computer typed 'o',
+	you typed 'r',
+	computer typed 'r',
+	...
+.fi
+
+Without specific knowledge of the program, it is impossible to know if
+you are waiting to see each character echoed before typing the next.
+If autoexpect sees characters being echoed, it assumes that it can
+send them all as a group rather than interleaving them the way they
+originally appeared.  This makes the script more pleasant to read.
+However, it could conceivably be incorrect if you really had to wait
+to see each character echoed.
+
+.TP
+\(bu
+Change.  Autoexpect records every character from the interaction in
+the script.  This is desirable because it gives you the ability to
+make judgements about what is important and what can be replaced with
+a pattern match.
+
+On the other hand, if you use commands whose output differs from run
+to run, the generated scripts are not going to be correct.  For
+example, the "date" command always produces different output.  So
+using the date command while running autoexpect is a sure way to
+produce a script that will require editing in order for it to work.
+
+The \-p flag puts autoexpect into "prompt mode".  In this mode,
+autoexpect will only look for the the last line of program output \-
+which is usually the prompt.  This handles the date problem (see
+above) and most others.
+
+The following example starts autoexpect in prompt mode.
+.nf
+
+	autoexpect \-p
+
+.fi
+The \-P flag defines a key to toggle prompt mode.  The following
+example starts autoexpect (in non-prompt mode) with ^P as the toggle.
+Note that the ^P is entered literally - i.e., enter a real control-P.
+.nf
+
+	autoexpect \-P ^P
+
+.fi
+The following example starts autoexpect in prompt mode with ^P as the toggle.
+.nf
+
+	autoexpect \-p \-P ^P
+
+.fi
+.SH OTHER FLAGS
+The
+.B \-quiet
+flag disables informational messages produced by autoexpect.
+
+The
+.B \-Q
+flag names a quote character which can be used to enter characters
+that autoexpect would otherwise consume because they are used as toggles.
+
+The following example shows a number of flags with quote used to
+provide a way of entering the toggles literally.
+.nf
+
+	autoexpect \-P ^P \-C ^L \-Q ^Q
+
+.fi
+.SH STYLE
+
+I don't know if there is a "style" for Expect programs but autoexpect
+should definitely not be held up as any model of style.  For example,
+autoexpect uses features of Expect that are intended specifically for
+computer-generated scripting.  So don't try to faithfully write
+scripts that appear as if they were generated by autoexpect.  This is
+not useful.
+
+On the other hand, autoexpect scripts do show some worthwhile things.
+For example, you can see how any string must be quoted in order to use
+it in a Tcl script simply by running the strings through autoexpect.

+
+# Unlike programs (http://www.ionet.net/~timtroyr/funhouse/beer.html)
+# which merely print out the 99 verses, this one SIMULATES a human
+# typing the beer song.  Like a real human, typing mistakes and timing
+# becomes more erratic with each beer - the final verse is barely
+# recognizable and it is really like watching a typist hunt and peck
+# while drunk.
+
+# Finally, no humans actually sing all 99 verses - particularly when
+# drunk.  In reality, they occasionally lose their place (or just get
+# bored) and skip verses, so this program does likewise.
+
+# Because the output is timed, just looking at the output isn't enough
+# - you really have to see the program running to appreciate it.
+# Nonetheless, for convenience, output from one run (it's different
+# every time of course) can be found in the file beer.exp.out
+# But it won't show the erratic timing; you have to run it for that.
+
+# For an even fancier version, see http://expect.nist.gov/scripts/superbeer.exp

+.B cryptdir
+encrypts all files in the current directory (or the given directory

+(i.e., same program, different name), all files are decrypted.
+
+.SH NOTES
+When encrypting, you are prompted twice for the password as a
+precautionary measure.  It would be a disaster to encrypt files with a
+password that wasn't what you intended.
+
+In contrast, when decrypting, you are only prompted once.  If it's the
+wrong password, no harm done.
+
+Encrypted files have the suffix .crypt appended.  This prevents files
+from being encrypted twice.  The suffix is removed upon decryption.
+Thus, you can easily add files to an encrypted directory and run
+cryptdir on it without worrying about the already encrypted files.

+.TH DISLOCATE 1 "7 October 1993"
+.SH NAME
+Dislocate \- disconnect and reconnect processes
+.SH SYNOPSIS
+.B dislocate
+
+.I program args...
+
+.SH INTRODUCTION
+.B Dislocate
+allows processes to be disconnected and reconnected to the terminal.
+Possible uses:
+.RS
+.TP 4
+\(bu
+You can disconnect a process from a terminal at work
+and reconnect from home, to continue working.
+.TP 4
+\(bu
+After having your line be dropped due to noise, you can get back to your
+process without having to restart it from scratch.
+.TP 4
+\(bu
+If you have a problem that you would like to show someone, you can set
+up the scenario at your own terminal, disconnect, walk down the hall,
+and reconnect on another terminal.
+.TP 4
+\(bu
+If you are in the middle of a great game (or whatever) that does not allow
+you to save, and someone else kicks you off the terminal, you can disconnect,
+and reconnect later.
+.SH USAGE
+When run with no arguments,
+.B Dislocate
+tells you about your disconnected processes and lets you reconnect to one.
+Otherwise,
+.B Dislocate
+runs the named program along with any arguments.
+
+By default, ^ is an escape that lets you talk to
+.B Dislocate
+itself.  At that point, you can disconnect (by pressing ^D) or
+suspend
+.B Dislocate
+(by pressing ^Z).
+
+Any Tcl or Expect command is also acceptable at this point.
+For example,
+to insert the contents of a the file /etc/motd as if you had typed it, say:
+.nf
+
+     send -i $out exec cat /etc/motd
+
+.fi
+
+To send the numbers 1 to 100 in response to the prompt "next #", say:
+.nf
+
+     for {set i 0} {$i<100} {incr i} {
+         expect -i $in "next #"
+         send -i $out "$i\\r"
+     }
+.fi
+
+Scripts can also be prepared and sourced in so that you don't have to
+type them on the spot.
+
+.B Dislocate
+is actually just a simple
+.B Expect
+script.  Feel free to make it do what you want it to do or just
+use
+.B Expect
+directly, without going through
+.BR Dislocate .
+.B Dislocate
+understands a few special arguments.  These should appear before any program
+name.  Each should be separated by whitespace.  If the arguments themselves
+takes arguments, these should also be separated by whitespace.
+.PP
+The
+.B \-escape
+flag sets the escape to whatever follows.  The default escape is ^.
+.PP
+.SH CAVEATS
+This program was written by the author as an exercise to show that
+communicating with disconnected processes is easy.  There are
+many features that could be added, but that is not the intent of this
+program.

+# Name: getpassck
+#
+# Description:
+#    This script demonstrates when programs using getpass sometimes
+#    fail.  The reason is that some implementations of getpass prompt
+#    before the pty/tty has completed the switch to no-echo.  This may
+#    not be obvious from examination of the implementation of getpass
+#    itself because the driver itself may cut corners and be
+#    responsible for allowing the call to return prematurely.
+#
+# Directions:
+#   Simply run this script.  It will loop 100 times attempting to
+#   generate the getpass problem.  If the bug cannot be reproduced,
+#   you will see 100 failed attempts to su.  If the bug can be
+#   reproduced, the script exits as soon as it is detected.

+.TH KIBITZ 1 "19 October 1994"
+.SH NAME
+kibitz \- allow two people to interact with one shell
+.SH SYNOPSIS
+.B kibitz
+
+.I kibitz-args
+
+.I user
+
+.I program program-args...
+
+.br
+.B kibitz
+
+.I kibitz-args
+
+.I user@host
+
+.I program program-args...
+
+.SH INTRODUCTION
+.B kibitz
+allows two (or more) people to interact with one shell (or any arbitrary
+program).  Uses include:
+.RS
+.TP 4
+\(bu
+A novice user can ask an expert user for help.  Using
+.BR kibitz ,
+the expert can see what the user is doing, and offer advice or
+show how to do it right.
+.TP
+\(bu
+By running
+.B kibitz
+and then starting a full-screen editor, people may carry out a
+conversation, retaining the ability to scroll backwards,
+save the entire conversation, or even edit it while in progress.
+.TP
+\(bu
+People can team up on games, document editing, or other cooperative
+tasks where each person has strengths and weaknesses that complement one
+another.
+.SH USAGE
+To start
+.BR kibitz ,
+user1
+runs kibitz with the argument of the
+user to kibitz.  For example:
+
+	kibitz user2
+
+.B kibitz
+starts a new shell (or another program, if given on the command
+line), while prompting user2 to run
+.BR kibitz .
+If user2 runs
+.B kibitz
+as directed, the keystrokes of both users become the input of
+the shell.  Similarly, both users receive the output from the
+shell.
+
+To terminate
+.B kibitz
+it suffices to terminate the shell itself.  For example, if either user
+types ^D (and the shell accepts this to be EOF), the shell terminates
+followed by
+.BR kibitz .
+
+Normally, all characters are passed uninterpreted.  However, if the
+escape character (described when
+.B kibitz
+starts) is issued, the user
+may talk directly to the
+.B kibitz
+interpreter.  Any
+.BR Expect (1)
+or
+.BR Tcl (3)
+commands may be given.
+Also, job control may be used while in the interpreter, to, for example,
+suspend or restart
+.BR kibitz .
+
+Various processes
+can provide various effects.  For example, you can emulate a two-way write(1)
+session with the command:
+
+	kibitz user2 sleep 1000000
+.SH ARGUMENTS
+.B kibitz
+takes arguments, these should also be separated by whitespace.
+
+The
+.B \-noproc
+flag runs
+.B kibitz
+with no process underneath.  Characters are passed to the other
+.BR kibitz .
+This is particularly useful for connecting multiple
+interactive processes together.
+In this mode, characters are not echoed back to the typist.
+
+.B \-noescape
+disables the escape character.
+
+.BI \-escape " char"
+sets the escape character.  The default escape character is ^.
+
+.B \-silent
+turns off informational messages describing what kibitz is doing to
+initiate a connection.
+
+.BI \-tty " ttyname"
+defines the tty to which the invitation should be sent.
+
+If you start
+.B kibitz
+to user2 on a remote computer,
+.B kibitz
+performs a
+.B rlogin
+to the remote computer with your current username. The flag
+.BI \-proxy " username"
+causes
+.B rlogin
+to use
+.I username
+for the remote login (e.g. if your account on the remote computer has a 
+different username). If the
+.B -proxy
+flag is not given,
+.B kibitz
+tries to determine your current username by (in that order) inspecting the
+environment variables USER and LOGNAME, then by using the commands
+.B whoami
+and
+.BR logname .
+
+The arguments
+.B -noescape
+and
+.B -escape
+can also be given by user2 when prompted to run
+.BR kibitz .
+
+.SH MORE THAN TWO USERS
+The current implementation of kibitz explicitly understands only two users,
+however, it is nonetheless possible to have a three (or more) -way kibitz,
+by kibitzing another
+.BR kibitz .
+For example, the following command runs
+.B kibitz
+with the current user, user2, and user3:
+
+	% kibitz user2 kibitz user3
+
+Additional users may be added by simply appending more "kibitz user"
+commands.
+
+The
+.B xkibitz
+script is similar to
+.B kibitz
+but supports the ability to add additional users (and drop them)
+dynamically.
+.SH CAVEATS
+.B kibitz
+assumes the 2nd user has the same terminal type and size as the 1st user.
+If this assumption is incorrect, graphical programs may display oddly.
+
+.B kibitz
+handles character graphics, but cannot handle bitmapped graphics.  Thus,
+.nf
+
+	% xterm -e kibitz    will work
+	% kibitz xterm       will not work
+
+.fi
+However, you can get the effect of the latter command by using
+.B xkibitz 
+(see SEE ALSO below).
+.B kibitz
+uses the same permissions as used by rlogin, rsh, etc.  Thus, you
+can only
+.B kibitz
+to users at hosts for which you can rlogin.
+Similarly,
+.B kibitz
+will prompt for a password on the remote host if
+rlogin would.
+
+If you
+.B kibitz
+to users at remote hosts,
+.B kibitz
+needs to distinguish your prompt from other things that may precede it
+during login.
+(Ideally, the end of it is preferred but any part should suffice.)
+If you have an unusual prompt,
+set the environment variable EXPECT_PROMPT to an egrep(1)-style
+regular expression.
+Brackets should be preceded with one backslash in ranges,
+and three backslashes for literal brackets.
+The default prompt r.e. is "($|%|#)\ ".
+
+.B kibitz
+requires the
+.B kibitz
+program on both hosts.
+.B kibitz
+requires
+.BR expect (1).
+
+By comparison, the
+.B xkibitz
+script uses the X authorization mechanism for inter-host communication
+so it does not need to login, recognize your prompt, or require kibitz
+on the remote host.  It does however need permission to access
+the other X servers.
+.SH BUGS
+An early version of Sun's tmpfs had a bug in it that causes
+.B kibitz
+to blow up.  If
+.B kibitz
+reports "error flushing ...: Is a directory"
+ask Sun for patch #100174.
+
+If your Expect is not compiled with multiple-process support (i.e., you do not 
+have a working select or poll), you will not be able to run kibitz.
+.SH ENVIRONMENT
+The environment variable SHELL is used to determine the shell to start, if no
+other program is given on the command line.
+
+If the environment variable EXPECT_PROMPT exists, it is taken as a regular
+expression which matches the end of your login prompt (but does not otherwise
+occur while logging in). See also CAVEATS above.
+
+If the environment variables USER or LOGNAME are defined, they are used to 
+determine the current user name for a
+.B kibitz
+to a remote computer. See description of the
+.B -proxy
+option in ARGUMENTS above.

+.SH SYNOPSIS
+.B mkpasswd
+.I
+
+.I args
+
+
+.I user
+
+.SH INTRODUCTION
+.B mkpasswd
+generates passwords and can apply them automatically to users.
+mkpasswd is based on the code from Chapter 23 of the O'Reilly book
+"Exploring Expect".
+.SH USAGE
+With no arguments,
+.B mkpasswd
+returns a new password.
+
+	mkpasswd
+
+With a user name,
+.B mkpasswd
+assigns a new password to the user.
+
+	mkpasswd don
+
+The passwords are randomly generated according to the flags below.
+
+.SH FLAGS
+The
+.B \-l
+flag defines the length of the password.  The default is 9.  
+The following example creates a 20 character password.
+
+	mkpasswd -l 20
+
+The
+.B \-d
+flag defines the minimum number of digits that must be in the password.
+The default is 2.  The following example creates a password with at least
+3 digits.
+
+	mkpasswd -d 3
+
+The
+.B \-c
+flag defines the minimum number of lowercase alphabetic characters that must be in the password.
+The default is 2.
+
+The
+.B \-C
+flag defines the minimum number of uppercase alphabetic characters that must be in the password.
+The default is 2.
+
+The
+.B \-s
+flag defines the minimum number of special characters that must be in the password.
+The default is 1.
+
+The
+.B \-p
+flag names a program to set the password.
+By default, /etc/yppasswd is used if present, otherwise /bin/passwd is used.
+
+The
+.B \-2
+flag causes characters to be chosen so that they alternate between
+right and left hands (qwerty-style), making it harder for anyone
+watching passwords being entered.  This can also make it easier for
+a password-guessing program.
+
+The
+.B \-v
+flag causes the password-setting interaction to be visible.
+By default, it is suppressed.
+
+.SH EXAMPLE
+The following example creates a 15-character password
+that contains at least 3 digits and 5 uppercase characters.
+
+	mkpasswd -l 15 -d 3 -C 5

+# NAME
+#	multixterm - drive multiple xterms separately or together
+#
+# SYNOPSIS
+#	multixterm -xa "xterm args"
+#		   -xc "command"
+#		   -xd "directory"
+#		   -xf "file"
+#		   -xn "xterm names"
+#		   -xv (enable verbose mode)
+#		   -xh or -x? (help)
+#		   xterm names or user-defined args...
+#
+# DESCRIPTION
+#	Multixterm creates multiple xterms that can be driven together
+#	or separately.
+#
+#	In its simplest form, multixterm is run with no arguments and
+#	commands are interactively entered in the first entry field.
+#	Press return (or click the "new xterm" button) to create a new
+#	xterm running that command.
+#
+#	Keystrokes in the "stdin window" are redirected to all xterms
+#	started by multixterm.  xterms may be driven separately simply
+#	by focusing on them.
+#
+#	The stdin window must have the focus for keystrokes to be sent
+#	to the xterms.  When it has the focus, the color changes to
+#	aquamarine.  As characters are entered, the color changes to
+#	green for a second.  This provides feedback since characters
+#	are not echoed in the stdin window.
+#
+#	Typing in the stdin window while holding down the alt or meta
+#	keys sends an escape character before the typed characters.
+#	This provides support for programs such as emacs.
+#
+# ARGUMENTS
+#	The optional -xa argument indicates arguments to pass to
+#	xterm.
+#
+#	The optional -xc argument indicates a command to be run in
+#	each named xterm (see -xn).  With no -xc argument, the command
+#	is the current shell.
+#
+#	The optional -xd argument indicates a directory to search for
+#	files that will appear in the Files menu.  By default, the
+#	directory is: ~/lib/multixterm
+#
+#	The optional -xf argument indicates a file to be read at
+#	startup.  See FILES below for more info.
+#
+#	The optional -xn argument indicates a name for each xterm.
+#	This name will also be substituted for any %n in the command
+#	argument (see -xc).
+#
+#	The optional -xv flag puts multixterm into a verbose mode
+#	where it will describe some of the things it is doing
+#	internally.  The verbose output is not intended to be
+#	understandable to anyone but the author.
+#
+#	Less common options may be changed by the startup file (see
+#	FILES below).
+#
+#	All the usual X and wish flags are supported (i.e., -display,
+#	-name).  There are so many of them that to avoid colliding and
+#	make them easy to remember, all the multixterm flags begin
+#	with -x.
+#
+#	If any arguments do not match the flags above, the remainder
+#	of the command line is made available for user processing.  By
+#	default, the remainder is used as a list of xterm names in the
+#	style of -xn. The default behavior may be changed using the
+#	.multixtermrc file (see DOT FILE below).
+#
+# EXAMPLE COMMAND LINE ARGUMENTS
+#	The following command line starts up two xterms using ssh to
+#	the hosts bud and dexter.
+#
+#		multixterm -xc "ssh %n" bud dexter
+#
+# FILES
+#	Command files may be used to drive or initialize multixterm.
+#	The File menu may be used to invoke other files.  If files
+#	exist in the command file directory (see -xd above), they will
+#	appear in the File menu.  Files may also be loaded by using
+#	File->Open.  Any filename is acceptable but the File->Open
+#	browser defaults to files with a .mxt suffix.
+#
+#	Files are written in Tcl and may change any variables or
+#	invoke any procedures.  The primary variables of interest are
+#	'xtermCmd' which identifies the command (see -xc) and
+#	'xtermNames' which is a list of names (see -xn).  The
+#	procedure xtermStartAll, starts xterms for each name in the
+#	list.  Other variables and procedures may be discovered by
+#	examining multixterm itself.
+#
+# EXAMPLE FILE
+#	The following file does the same thing as the earlier example
+#	command line:
+#
+#		# start two xterms connected to bud and dexter
+#		set xtermCmd "ssh %n"
+#		set xtermNames {bud dexter}
+#		xtermStartAll
+#
+# DOT FILE
+#	At startup, multixterm reads ~/.multixtermrc if present.  This
+#	is similar to the command files (see FILES above) except that
+#	.multixtermrc may not call xtermStartAll.  Instead it is
+#	called implicitly, similar to the way that it is implicit in
+#	the command line use of -xn.
+#
+#	The following example .multixtermrc file makes every xterm run
+#	ssh to the hosts named on the command line.
+#
+#		set xtermCmd "ssh %n"
+#
+#	Then multixterm could be called simply:
+#
+#		multixterm bud dexter
+#
+#	If any command-line argument does not match a multixterm flag,
+#	the remainder of the command line is made available to
+#	.multixtermrc in the argv variable.  If argv is non-empty when
+#	.multixtermrc returns, it is assigned to xtermNames unless
+#	xtermNames is non-empty in which case, the content of argv is
+#	ignored.
+#
+#	Commands from .multixtermrc are evaluated early in the
+#	initialization of multixterm.  Anything that must be done late
+#	in the initialization (such as adding additional bindings to
+#	the user interface) may be done by putting the commands inside
+#	a procedure called "initLate".
+#
+# MENUS
+#	Except as otherwise noted, the menus are self-explanatory.
+#	Some of the menus have dashed lines as the first entry.
+#	Clicking on the dashed lines will "tear off" the menus.
+#
+# USAGE SUGGESTION - ALIASES AND COMMAND FILES
+#	Aliases may be used to store lengthy command-line invocations.
+#	Command files can be also be used to store such invocations
+#	as well as providing a convenient way to share configurations.
+#
+#	Tcl is a general-purpose language.  Thus multixterm command
+#	files can be extremely flexible, such as loading hostnames
+#	from other programs or files that may change from day-to-day.
+#	In addition, command files can be used for other purposes.
+#	For example, command files may be used to prepared common
+#	canned interaction sequences.  For example, the command to
+#	send the same string to all xterms is:
+#
+#	    xtermSend "a particularly long string"
+#
+#	The File menu (torn-off) makes canned sequences particularly
+#	convenient.  Interactions could also be bound to a mouse
+#	button, keystroke, or added to a menu via the .multixtermrc
+#	file.
+#
+# USAGE SUGGESTION - HANDLING MANY XTERMS BY TILING
+#	The following .multixtermrc causes tiny xterms to tile across
+#	and down the screen.  (You may have to adjust the parameters
+#	for your screen.)  This can be very helpful when dealing with
+#	large numbers of xterms.
+#
+#	    set yPos 0
+#	    set xPos 0
+#
+#	    trace variable xtermArgs r traceArgs
+#
+#	    proc traceArgs {args} {
+#	        global xPos yPos
+#	        set ::xtermArgs "-geometry 80x12+$xPos+$yPos -font 6x10"
+#	        if {$xPos} {
+#		    set xPos 0
+#		    incr yPos 145
+#		    if {$yPos > 800} {set yPos 0}
+#	        } else {
+#		    set xPos 500
+#	        }
+#	    }
+#
+#	The xtermArgs variable in the code above is the variable
+#	corresponding to the -xa argument.
+#
+#	xterms can be also be created directly.  The following command
+#	file creates three xterms overlapped horizontally:
+#
+#	    set xPos 0
+#
+#	    foreach name {bud dexter hotdog} {
+#	        set ::xtermArgs "-geometry 80x12+$xPos+0 -font 6x10"
+#	        set ::xtermNames $name
+#	        xtermStartAll
+#	        incr xPos 300
+#	    }
+#
+# USAGE SUGGESTION - SELECTING HOSTS BY NICKNAME
+#	The following .multixtermrc shows an example of changing the
+#	default handling of the arguments from hostnames to a filename
+#	containing hostnames:
+#
+#		set xtermNames exec cat $argv
+#
+#	The following is a variation, retrieving the host names from
+#	the yp database:
+#
+#		set xtermNames exec ypcat $argv
+#
+#	The following hardcodes two sets of hosts, so that you can
+#	call multixterm with either "cluster1" or "cluster2":
+#
+#		switch $argv {
+#		    cluster1 {
+#			set xtermNames "bud dexter"
+#		    }
+#		    cluster2 {
+#			set xtermNames "frank hotdog weiner"
+#		    }
+#		}
+#
+# COMPARE/CONTRAST
+#	It is worth comparing multixterm to xkibitz.  Multixterm
+#	connects a separate process to each xterm.  xkibitz connects
+#	the same process to each xterm.
+#
+# LIMITATIONS
+#	Multixterm provides no way to remotely control scrollbars,
+#	resize, and most other window system related functions.
+#
+#	Multixterm can only control new xterms that multixterm itself
+#	has started.
+#
+#	As a convenience, the File menu shows a limited number of
+#	files.  To show all the files, use File->Open.
+#
+# FILES
+#	$DOTDIR/.multixtermrc   initial command file
+#	~/.multixtermrc         fallback command file
+#	~/lib/multixterm/       default command file directory
+#
+# BUGS
+#	If multixterm is killed using an uncatchable kill, the xterms
+#	are not killed.  This appears to be a bug in xterm itself.
+#
+#	Send/expect sequences can be done in multixterm command files.
+#	However, due to the richness of the possibilities, to document
+#	it properly would take more time than the author has at present.
+#
+# REQUIREMENTS
+#	Requires Expect 5.36.0 or later.
+#	Requires Tk 8.3.3 or later.
+#

+.TH MULTIXTERM 1 "16 August 2002"
+.SH NAME
+multixterm \- drive multiple xterms separately or together
+.SH SYNOPSIS
+.B multixterm
+
+.I args
+
+.SH DESCRIPTION
+Multixterm creates multiple xterms that can be driven together
+or separately.
+
+In its simplest form, multixterm is run with no arguments and
+commands are interactively entered in the first entry field.
+Press return (or click the "new xterm" button) to create a new
+xterm running that command.
+
+Keystrokes in the "stdin window" are redirected to all xterms
+started by multixterm.  xterms may be driven separately simply
+by focusing on them.
+
+The stdin window must have the focus for keystrokes to be sent
+to the xterms.  When it has the focus, the color changes to
+aquamarine.  As characters are entered, the color changes to
+green for a second.  This provides feedback since characters
+are not echoed in the stdin window.
+
+Typing in the stdin window while holding down the alt or meta
+keys sends an escape character before the typed characters.
+This provides support for programs such as emacs.
+
+.SH ARGUMENTS
+.RS
+.TP 4
+-xa
+The optional \-xa argument indicates arguments to pass to
+xterm.
+
+.TP
+-xc
+The optional \-xc argument indicates a command to be run in
+each named xterm (see \-xn).  With no \-xc argument, the command
+is the current shell.
+
+.TP 4
+-xd
+The optional \-xd argument indicates a directory to search for
+files that will appear in the Files menu.  By default, the
+directory is: ~/lib/multixterm
+
+.TP 4
+-xf
+The optional \-xf argument indicates a file to be read at
+startup.  See FILES below for more info.
+
+.TP 4
+-xn
+The optional \-xn argument indicates a name for each xterm.
+This name will also be substituted for any %n in the command
+argument (see \-xc).
+
+.TP 4
+-xv
+The optional \-xv flag puts multixterm into a verbose mode
+where it will describe some of the things it is doing
+internally.  The verbose output is not intended to be
+understandable to anyone but the author.
+
+.RE
+Less common options may be changed by the startup file (see
+FILES below).
+
+All the usual X and wish flags are supported (i.e., \-display,
+\-name).  There are so many of them that to avoid colliding and
+make them easy to remember, all the multixterm flags begin
+with \-x.
+
+If any arguments do not match the flags above, the remainder of the
+command line is made available for user processing.  By default, the
+remainder is used as a list of xterm names in the style of \-xn.  The
+default behavior may be changed using the .multixtermrc file (see DOT
+FILE below).
+
+.SH "EXAMPLE COMMAND LINE ARGUMENTS"
+The following command line starts up two xterms using ssh to
+the hosts bud and dexter.
+
+	multixterm \-xc "ssh %n" bud dexter
+
+.SH FILES
+Command files may be used to drive or initialize multixterm.
+The File menu may be used to invoke other files.  If files
+exist in the command file directory (see \-xd above), they will
+appear in the File menu.  Files may also be loaded by using
+File->Open.  Any filename is acceptable but the File->Open
+browser defaults to files with a .mxt suffix.
+
+Files are written in Tcl and may change any variables or
+invoke any procedures.  The primary variables of interest are 'xtermCmd'
+which identifies the command (see \-xc) and 'xtermNames'
+which is a list of names (see \-xn).  The procedure
+xtermStartAll, starts xterms for each name in the list.  Other
+variables and procedures may be discovered by examining
+multixterm itself.
+
+.SH "EXAMPLE FILE"
+The following file does the same thing as the earlier example
+command line:
+.nf
+
+	# start two xterms connected to bud and dexter
+	set xtermCmd "ssh %n"
+	set xtermNames {bud dexter}
+	xtermStartAll
+
+.fi
+.SH "DOT FILE"
+At startup, multixterm reads ~/.multixtermrc if present.  This
+is similar to the command files (see FILES above) except
+that .multixtermrc may not call xtermStartAll.  Instead it is
+called implicitly, similar to the way that it is implicit in
+the command line use of \-xn.
+
+The following example .multixtermrc file makes every xterm run
+ssh to the hosts named on the command line.
+
+	set xtermCmd "ssh %n"
+
+Then multixterm could be called simply:
+
+	multixterm bud dexter
+
+If any command-line argument does not match a multixterm flag,
+the remainder of the command line is made available to .multixtermrc
+in the argv variable.  If argv is non-empty when .multixtermrc returns, it is assigned to xtermNames unless xtermNames is non-empty in which case, the
+content of argv is ignored.
+
+Commands from multixterm are evaluated early in the
+initialization of multixterm.  Anything that must be done late
+in the initialization (such as adding additional bindings to
+the user interface) may be done by putting the commands inside
+a procedure called "initLate".
+
+.SH MENUS
+Except as otherwise noted, the menus are self-explanatory.
+Some of the menus have dashed lines as the first entry.
+Clicking on the dashed lines will "tear off" the menus.
+
+.SH "USAGE SUGGESTION \- ALIASES AND COMMAND FILES"
+Aliases may be used to store lengthy command-line invocations.
+Command files can be also be used to store such invocations
+as well as providing a convenient way to share configurations.
+
+Tcl is a general-purpose language.  Thus multixterm command
+files can be extremely flexible, such as loading hostnames
+from other programs or files that may change from day-to-day.
+In addition, command files can be used for other purposes.
+For example, command files may be used to prepared common
+canned interaction sequences.  For example, the command to
+send the same string to all xterms is:
+
+    xtermSend "a particularly long string"
+
+The File menu (torn-off) makes canned sequences particularly
+convenient.  Interactions could also be bound to a mouse button,
+keystroke, or added to a menu via the .multixtermrc file.
+
+The following .multixtermrc causes tiny xterms to tile across
+and down the screen.  (You may have to adjust the parameters
+for your screen.)  This can be very helpful when dealing with
+large numbers of xterms.
+.nf
+
+    set yPos 0
+    set xPos 0
+
+    trace variable xtermArgs r traceArgs
+
+    proc traceArgs {args} {
+        global xPos yPos
+        set ::xtermArgs "-geometry 80x12+$xPos+$yPos \-font 6x10"
+        if {$xPos} {
+            set xPos 0
+            incr yPos 145
+            if {$yPos > 800} {set yPos 0}
+        } else {
+            set xPos 500
+        }
+    }
+.fi
+
+The xtermArgs variable in the code above is the variable corresponding
+to the \-xa argument.
+
+xterms can be also be created directly.  The following command file
+creates three xterms overlapped
+horizontally:
+.nf
+
+    set xPos 0
+    foreach name {bud dexter hotdog} {
+        set ::xtermArgs "-geometry 80x12+$xPos+0 \-font 6x10"
+        set ::xtermNames $name
+        xtermStartAll
+        incr xPos 300
+    }
+
+.fi
+.SH "USAGE SUGGESTION \- SELECTING HOSTS BY NICKNAME"
+The following .multixtermrc shows an example of changing the
+default handling of the arguments from hostnames to a filename
+containing hostnames:
+
+	set xtermNames exec cat $argv
+
+The following is a variation, retrieving the host names from
+the yp database:
+
+	set xtermNames exec ypcat $argv
+
+The following hardcodes two sets of hosts, so that you can
+call multixterm with either "cluster1" or "cluster2":
+.nf
+
+	switch $argv {
+            cluster1 {
+                set xtermNames "bud dexter"
+            }
+            cluster2 {
+                set xtermNames "frank hotdog weiner"
+            }
+        }
+
+.fi
+
+
+.SH COMPARE/CONTRAST
+It is worth comparing multixterm to xkibitz.  Multixterm
+connects a separate process to each xterm.  xkibitz connects
+the same process to each xterm.
+
+.SH LIMITATIONS
+
+Multixterm provides no way to remotely control scrollbars, resize, and
+most other window system related functions.  
+
+Because xterm has no mechanism for propagating size information to
+external processes, particularly for character graphic applications
+(e.g., vi, emacs), you may have to manually ensure that the spawned
+process behind each xterm has the correct size.  For example, if you
+create or set the xterm to a size, you may have to send an explicit
+stty command with the correct size to the spawned process(es).
+Alternatively, you can add the correct size argument when an xterm is
+created (i.e., "-geometry 80x20").
+
+Multixterm can only control new xterms that multixterm itself has
+started.
+
+As a convenience, the File menu shows a limited number of
+files.  To show all the files, use File->Open.
+
+.SH FILES
+$DOTDIR/.multixtermrc   initial command file
+.br
+~/.multixtermrc         fallback command file
+.br
+~/lib/multixterm/       default command file directory
+
+.SH BUGS
+If multixterm is killed using an uncatchable kill, the xterms
+are not killed.  This appears to be a bug in xterm itself.
+
+Send/expect sequences can be done in multixterm command files.
+However, due to the richness of the possibilities, to document
+it properly would take more time than the author has at present.
+
+.SH REQUIREMENTS
+Requires Expect 5.36.0 or later.
+.br
+Requires Tk 8.3.3 or later.
+
+.SH VERSION
+This man page describes version 1.8 of multixterm.
+
+The latest version of multixterm is available from
+http://expect.nist.gov/example/multixterm .  If your version of Expect
+and Tk are too old (see REQUIREMENTS above), download a new version of
+Expect from http://expect.nist.gov
+
+.SH DATE
+April 30, 2002
+
+.SH AUTHOR
+Don Libes <don@libes.com>
+
+.SH LICENSE
+Multixterm is in the public domain; however the author would
+appreciate acknowledgement if multixterm or parts of it or ideas from
+it are used.

+.TH PASSMASS 1 "7 October 1993"
+.SH NAME
+passmass \- change password on multiple machines
+.SH SYNOPSIS
+.B passmass
+
+.I host1 host2 host3 ...
+
+.SH INTRODUCTION
+.B Passmass
+changes a password on multiple machines.  If you have accounts on
+several machines that do not share password databases, Passmass can
+help you keep them all in sync.  This, in turn, will make it easier to
+change them more frequently.
+
+When Passmass runs, it asks you for the old and new passwords.
+(If you are changing root passwords and have equivalencing, the old
+password is not used and may be omitted.)
+
+Passmass understands the "usual" conventions.  Additional arguments
+may be used for tuning.  They affect all hosts which follow until
+another argument overrides it.  For example, if you are known as
+"libes" on host1 and host2, but "don" on host3, you would say:
+
+	passmass host1 host2 -user don host3
+
+Arguments are:
+.RS
+.TP 4
+-user
+User whose password will be changed.  By default, the current user is used.
+
+.TP 4
+-rlogin
+Use rlogin to access host.  (default)
+
+.TP 4
+-slogin
+Use slogin to access host.
+
+.TP 4
+-ssh
+Use ssh to access host.
+
+.TP 4
+-telnet
+Use telnet to access host.
+
+.TP 4
+-program
+
+Next argument is a program to run to set the password.  Default is
+"passwd".  Other common choices are "yppasswd" and "set passwd" (e.g.,
+VMS hosts).  A program name such as "password fred" can be used to
+create entries for new accounts (when run as root).
+
+.TP 4
+-prompt
+Next argument is a prompt suffix pattern.  This allows
+the script to know when the shell is prompting.  The default is
+"# " for root and "% " for non-root accounts.
+
+.TP 4
+-timeout
+Next argument is the number of seconds to wait for responses.
+Default is 30 but some systems can be much slower logging in.
+
+.TP 4
+-su
+
+Next argument is 1 or 0.  If 1, you are additionally prompted for a
+root password which is used to su after logging in.  root's password
+is changed rather than the user's.  This is useful for hosts which
+do not allow root to log in.
+
+.SH HOW TO USE
+The best way to run Passmass is to put the command in a one-line shell
+script or alias.  Whenever you get a new account on a new machine, add
+the appropriate arguments to the command.  Then run it whenever you
+want to change your passwords on all the hosts.
+
+.SH CAVEATS
+
+Using the same password on multiple hosts carries risks.  In
+particular, if the password can be stolen, then all of your accounts
+are at risk.  Thus, you should not use Passmass in situations where
+your password is visible, such as across a network which hackers are
+known to eavesdrop.
+
+On the other hand, if you have enough accounts with different
+passwords, you may end up writing them down somewhere - and
+.I that
+can be a security problem.  Funny story: my college roommate had an
+11"x13" piece of paper on which he had listed accounts and passwords
+all across the Internet.  This was several years worth of careful work
+and he carried it with him everywhere he went.
+Well one day, he forgot to remove it from his jeans, and we found a
+perfectly blank sheet of paper when we took out the wash the following
+day!

+# This is a CGI script to process requests created by the accompanying

+# With a little more code, the script can do much more exotic things -

+# Don Libes, NIST
+exp_version -exit 5.0
+
+# rftp is much like ftp except that the command ~g copies everything in
+# the remote current working directory to the local current working
+# directory.  Similarly ~p copies in the reverse direction.  ~l just
+# lists the remote directories.
+
+# rftp takes an argument of the host to ftp to.  Username and password
+# are prompted for.  Other ftp options can be set interactively at that
+# time.  If your local ftp understands .netrc, that is also used.
+
+# ~/.rftprc is sourced after the user has logged in to the remote site
+# and other ftp commands may be sent at that time.  .rftprc may also be
+# used to override the following rftp defaults.  The lines should use
+# the same syntax as these:
+
+set file_timeout 3600		;# timeout (seconds) for retrieving files
+set timeout 1000000		;# timeout (seconds) for other ftp dialogue
+set default_type binary		;# default type, i.e., ascii, binary, tenex
+set binary {}			;# files matching are transferred as binary
+set ascii {}			;# as above, but as ascii
+set tenex {}			;# as above, but as tenex
+
+# The values of binary, ascii and tenex should be a list of (Tcl) regular
+# expressions.  For example, the following definitions would force files
+# ending in *.Z and *.tar to be transferred as binaries and everything else
+# as text.
+
+# set default_type ascii
+# set binary {*.Z *.tar}
+
+# If you are on a UNIX machine, you can probably safely ignore all of this
+# and transfer everything as "binary".
+
+# The current implementation requires that the source host be able to
+# provide directory listings in UNIX format.  Hence, you cannot copy
+# from a VMS host (although you can copy to it).  In fact, there is no
+# standard for the output that ftp produces, and thus, ftps that differ
+# significantly from the ubiquitous UNIX implementation may not work
+# with rftp (at least, not without changing the scanning and parsing).

+# Name: tkterm - terminal emulator using Expect and Tk text widget, v3.0
+# Author: Don Libes, July '94
+# Last updated: Mar '04
+
+# This is primarily for regression testing character-graphic applications.
+# You can certainly use it as a terminal emulator - however many features
+# in a real terminal emulator are not supported (although I'll probably
+# add some of them later).
+
+# A paper on the implementation: Libes, D., Automation and Testing of
+# Interactive Character Graphic Programs", Software - Practice &
+# Experience, John Wiley & Sons, West Sussex, England, Vol. 27(2),
+# p. 123-137, February 1997.
+
+###############################
+# Quick overview of this emulator
+###############################
+# Very good attributes:
+#   Understands both termcap and terminfo   
+#   Understands meta-key (zsh, emacs, etc work)
+#   Is fast
+#   Understands X selections
+#   Looks best with fixed-width font but doesn't require it
+#   Supports scrollbars
+# Good-enough-for-starters attributes:
+#   Understands one kind of standout mode (reverse video)
+# Should-be-fixed-soon attributes:
+#   Does not support resize
+# Probably-wont-be-fixed-soon attributes:
+#   Assumes only one terminal exists
+
+###############################################
+# To try out this package, just run it.  Using it in
+# your scripts is simple.  Here are directions:
+###############################################
+# 0) make sure Expect is linked into your Tk-based program (or vice versa)
+# 1) modify the variables/procedures below these comments appropriately
+# 2) source this file
+# 3) pack the text widget ($term) if you have so configured it (see
+#    "term_alone" below).  As distributed, it packs into . automatically.
+
+#############################################
+# Variables that must be initialized before using this:
+#############################################
+set rows 24		;# number of rows in term
+set rowsDumb $rows	;# number of rows in term when in dumb mode - this can
+			;# increase during runtime
+set cols 80		;# number of columns in term
+set term .t		;# name of text widget used by term
+set sb   .sb		;# name of scrollbar used by term in dumb mode
+set term_alone 1	;# if 1, directly pack term into .
+			;# else you must pack
+set termcap 1		;# if your applications use termcap
+set terminfo 1		;# if your applications use terminfo
+			;# (you can use both, but note that
+			;# starting terminfo is slow)
+set term_shell $env(SHELL) ;# program to run in term
+
+#############################################
+# Readable variables of interest
+#############################################
+# cur_row		;# current row where insert marker is
+# cur_col		;# current col where insert marker is
+# term_spawn_id		;# spawn id of term

+.TH TKNEWSBIFF 1 "1 January 1994"
+.SH NAME
+tknewsbiff \- pop up a window when news appears
+.SH SYNOPSIS
+.B tknewsbiff
+
+.I server or config-file
+
+.br
+.SH INTRODUCTION
+.B tknewsbiff
+pops up a window when there is unread news in your favorite newsgroups
+and removes the window after you've read the news.  tknewsbiff can
+optionally play a sound, start your newsreader, etc.
+
+.SH SELECTING NEWSGROUPS
+
+By default, the configuration file ~/.tknewsbiff describes how
+tknewsbiff behaves.  The syntax observes the usual Tcl rules
+- however, even if you don't know Tcl, all but the most esoteric
+configurations will be obvious.
+
+Each newsgroup (or set of newsgroups) to be watched is described by
+using the "watch" command.  For example:
+
+.nf
+
+watch dc.dining
+watch nist.*
+watch comp.unix.wizard  -threshold 3
+watch *.sources.*       -threshold 20
+
+.fi
+
+For each newsgroup pattern, any newsgroup that matches it and which
+you are subscribed to (according to your newsrc file) is eligible for
+reporting.  By default, tknewsbiff reports on the newsgroup if there
+is at least one unread article.  The "-threshold" flag changes the
+threshold to the following number.  For example, "-threshold 3" means
+there must be at least three articles unread before tknewsbiff will
+report the newsgroup.
+
+If no watch commands are given (or no configuration file exists), all
+groups which are subscribed to are watched.
+
+To suppress newsgroups that would otherwise be reported, use the
+"ignore" command.  For example, the following matches all comp.* and
+nist.* newgroups except for nist.posix or .d (discussion) groups:
+
+.nf
+
+watch comp.*
+watch nist.*
+ignore nist.posix.*
+ignore *.d
+
+.fi
+
+The flag "-new" describes a command to be executed when the newsgroup
+is first reported as having unread news.  For example, the following
+lines invoke the UNIX command "play" to play a sound.
+
+.nf
+
+watch dc.dining -new "exec play /usr/local/sounds/yumyum.au"
+watch rec.auto* -new "exec play /usr/local/sounds/vroom.au"
+
+.fi
+
+You can cut down on the verbosity of actions by defining procedures.
+For example, if you have many -new flags that all play sound files,
+you could define a sound procedure.  This would allow the -new
+specification to be much shorter.
+
+.nf
+
+proc play {sound} {
+	exec play /usr/local/sounds/$sound.au
+}
+
+watch dc.dining -new "play yumyum"
+watch rec.auto* -new "play vroom"
+
+.fi
+
+As an aside, you can put an "&" at the end of an "exec" command to get
+commands to execute asynchronously.  However, it's probably not a good
+idea to do this when playing sound files anyway.
+
+"newsgroup" is a read-only variable which contains the name of the
+newsgroup that is being reported.  This is useful when the action is
+triggered by a pattern.  For example, the following line could run the
+newsgroup name through a speech synthesizer:
+
+.nf
+
+watch * -new {
+	exec play herald.au
+	exec speak "New news has arrived in $newsgroup."
+}
+
+.fi
+
+The flag "\-display" describes a command to be executed every time the
+newsgroup is reported as having unread news.  The special command
+"display" is the default command.  It schedules $newsgroup to be
+written to tknewsbiff's display when it is rewritten.  For example, by
+explicitly providing a -display flag that omits the display command,
+you can disable the display of newsgroups that are already reported
+via -new.
+
+.nf
+
+watch dc.dining -new {exec play yumyum.au} -display {}
+
+.fi
+
+If you want to execute an action repeatedly and
+.I still
+display the newsgroup in the default manner,
+explicitly invoke the display command via the -display flag.  For example:
+
+.nf
+
+watch *security* -display {
+	exec play red-alert.au
+	display
+}
+
+.fi
+
+Actions associated with the -new and -display flags are executed only
+once for each matching newsgroup.  The command executed is the one
+associated with the first pattern in the configuration file that
+matches and observes the given threshold.
+
+Any command that is simply listed in the configuration file is
+executed each time before the update loop in tknewsbiff.  The reserved
+(but user-defined) procedure "user" is run immediately after the
+newsgroups are scheduled to be written to the display and before they
+are actually written.
+
+For example, suppose unread articles appear in several rec.auto groups
+and you play the same sound for each one.  To prevent playing the
+sound several times in a row, make the -new command simply set a flag.
+In the user procedure, play the sound if the flag is set (and then
+reset the flag).
+
+The user procedure could also be used to start a newsreader.  This
+would avoid the possibility of starting multiple newsreaders just
+because multiple newsgroups contained unread articles.  (A check
+should, of course, be made to make sure that a newsreader is not
+already running.)
+
+.SH MORE VARIABLES
+
+The following example lines show variables that can affect the
+behavior of tknewsbiff
+
+.nf
+
+set delay          120
+set server         news.nist.gov
+set server_timeout 60
+set newsrc         ~/.newsrc
+set width          40
+set height         20
+set active_file    /usr/news/lib/active
+
+.fi
+
+tknewsbiff alternates between checking for unread news and
+sleeping (kind of like many undergraduates).  The "delay" variable
+describes how many seconds to sleep.
+
+The "server" variable names an NNTP news-server.
+The default is "news".  The "server" variable is
+only used if the "active_file" variable is not set.
+
+The "server_timeout" variable describes how how many seconds to wait
+for a response from the server before giving up.  -1 means wait
+forever or until the server itself times out.  The default is 60
+seconds.
+
+The "newsrc" variable describes the name of your .newsrc file.  By
+default, tknewsbiff looks in your home directory for a newsrc file.  A
+server-specific newsrc is used if found.  For example, if you have set
+server to "cubit.nist.gov", then tknewsbiff looks for
+~/.newsrc-cubit.nist.gov.  (This is the Emacs gnus convention - which
+is very convenient when you read news from multiple servers.)  If
+there is no server-specific newsrc, tknewsbiff uses ~/.newsrc.
+
+The "width" variable describes the width that tknewsbiff will use to
+display information.  If any newsgroup names are long enough, they
+will be truncated so that the article counts can still be shown.  You
+can manually resize the window to see what was truncated.  However, if
+your configuration file sets the width variable, the window will be
+restored to that size the next time that tknewsbiff checks for unread
+news and updates its display.
+
+The "height" variable describes the maximum height that tknewsbiff
+will use to display information.  If fewer newsgroups are reported,
+tknewsbiff will shrink the window appropriately.  You can manually
+resize the window but if your configuration file sets the height
+variable, the window will be restored to that size the next time that
+tknewsbiff checks for unread news and updates its display.
+
+The "active_file" variable describes the name of the news active file.
+If set, the active file is read directly in preference to using NNTP
+(even if the "server" variable is set).  This is particularly useful
+for testing out new configuration files since you can edit a fake
+active file and then click button 2 to immediately see how tknewsbiff
+responds (see BUTTONS below).
+
+If the environment variable DOTDIR is set, then its value is used as a
+directory in which to find all dotfiles instead of from the home
+directory.  In particular, this affects the tknewsbiff configuration
+file and the .newsrc file (assuming the newsrc variable is not set
+explicitly).
+
+.SH WATCHING DIFFERENT NEWS SERVERS
+
+To watch multiple servers, run tknewsbiff multiple times.  (Since you
+need different .newsrc files and the servers have different newsgroups
+and article numbers anyway, there is no point in trying to do this in
+a single process.)
+
+You can point tknewsbiff at a different server with an appropriate
+argument.  The argument is tried both as a configuration file name and
+as a suffix to the string "~/.tknewsbiff-".  So if you want to watch
+the server "kidney", store the tknewsbiff configuration information in
+~/.tknewsbiff-kidney".  The following two commands will both use that
+configuration file.
+
+.nf
+
+	tknewsbiff kidney
+	tknewsbiff ~/.tknewsbiff-kidney
+
+.fi
+
+In both cases, the actual server to contact is set by the value of the
+server variable in the configuration file.
+
+If no configuration file is found, the argument is used as the server
+to contact.  This allows tknewsbiff to be run with no preparation
+whatsoever.
+
+If the argument is the special keyword "active" (or ends in
+"/active"), it is used as the name of an active file.  This is in turn
+used to initialize the variable "active_file" so that tknewsbiff reads
+from the active file directly rather than using NNTP.
+
+Creating your own active file is a convenient way of testing your
+configuration file.  For example, after running the following command,
+you can repeatedly edit your active file and trigger the update-now
+command (either by pressing button 2 or setting the delay variable
+very low) to see how tknewsbiff responds.
+
+The active file must follow the format of a real active file.  The
+format is one newsgroup per line.  After the newsgroup name is the
+number of the highest article, the lowest article.  Lastly is the
+letter y or m.  m means the newsgroup is moderated.  y means posting
+is allowed.
+
+.SH WINDOW
+
+When unread news is found, a window is popped up.  The window lists
+the names of the newsgroups and the number of unread articles in each
+(unless suppressed by the -display flag).  When there is no longer any
+unread news, the window disappears (although the process continues to
+run).
+
+.SH BUTTONS
+
+Button or key bindings may be assigned by bind commands.  Feel free to
+change them.  The default bind commands are:
+
+.nf
+
+bind .list <1> help
+bind .list <2> update-now
+bind .list <3> unmapwindow
+
+.fi
+
+By default button 1 (left) is bound to "help".  The help command
+causes tknewsbiff to pop up a help window.
+
+By default, button 2 (middle) is bound to "update-now".  The update-now
+command causes tknewsbiff to immediately check for unread news.  If
+your news server is slow or maintains a very large number of
+newsgroups, or you have a large number of patterns in your
+configuration file, tknewsbiff can take considerable time before
+actually updating the window.
+
+By default, button 3 (right) is bound to "unmapwindow".  The
+unmapwindow command causes tknewsbiff to remove the window from the
+display until the next time it finds unread news.  (The mapwindow
+command causes tknewsbiff to restore the window.)
+
+As an example, here is a binding to pop up an xterm and run rn when
+you hold down the shift key and press button 1 in the listing window.
+
+.nf
+
+bind .list <Shift-1> {
+	exec xterm -e rn &
+}
+
+.fi
+
+Here is a similar binding.  However it tells rn to look only at the
+newsgroup that is under the mouse when you pressed it.  (The
+"display_list" variable is described later in this man page.)
+
+.nf
+
+bind .list <Shift-1> {
+	exec xterm -e rn lindex $display_list .list nearest %y &
+}
+
+.fi
+
+.SH OTHER COMMANDS AND VARIABLES
+
+Built-in commands already mentioned are: watch, ignore, display, help,
+update-now, unmapwindow, and mapwindow.
+
+Any Tcl and Tk command can also be given.  In particular, the list of
+newsgroups is stored in the list widget ".list", and the scroll bar is
+stored in the scrollbar widget ".scroll".  So for example, if you want
+to change the foreground and background colors of the newsgroup list,
+you can say:
+
+.nf
+
+	.list config -bg honeydew1 -fg orchid2
+
+.fi
+
+These can also be controlled by the X resource database as well.
+However, the configuration file allows arbitrarily complex commands to
+be evaluated rather than simple assignments.
+
+Certain Tcl/Tk commands can disrupt proper function of tknewsbiff.
+These will probably be obvious to anyone who knows enough to give
+these commands in the first place.  As a simple example, the program
+assumes the font in the list box is of fixed width.  The newsgroups
+will likely not align if you use a variable-width font.
+
+The following variables are accessible and can be used for esoteric
+uses.  All other variables are private.  Private variables and
+commands begin with "_" so you don't need to worry about accidental
+collisions.
+
+The array "db" is a database which maintains information about read
+and unread news.  db($newsgroup,hi) is the highest article that
+exists.  db($newsgroup,seen) is the highest article that you have
+read.
+
+A number of lists maintain interesting information. "active_list" is a
+list of known newsgroups.  "seen_list" is a list of newsgroups that
+have been seen so far as the -new and -display flags are being
+processed.  "previous_seen_list" is "seen_list" from the previous
+cycle.  "ignore_list" is the list of newsgroup patterns to ignore.
+"watch_list" is the list of newsgroup patterns to watch.
+"display_list" is the list of newsgroup will be displayed at the next
+opportunity.
+
+.SH UPDATING YOUR FILES
+
+tknewsbiff automatically rereads your configuration file each time it
+wakes up to check for unread news.  To force tknewsbiff to reread the
+file immediately (such as if you are testing a new configuration or
+have just modified your newsrc file), press button 2 in the display
+(see BUTTONS above).
+
+.SH CAVEATS
+
+tknewsbiff defines the number of unread articles as the highest
+existing article minus the highest article that you've read.  So if
+you've read the last article in the newsgroup but no others,
+tknewsbiff thinks there are no unread articles.  (It's impossible to
+do any better by reading the active file and it would be very time
+consuming to do this more accurately via NNTP since servers provide no
+efficient way of reporting their own holes in the newsgroups.)
+Fortunately, this definition is considered a feature by most people.
+It allows you to read articles and then mark them "unread" but not
+have tknewsbiff continue telling you that they are unread.
+
+.SH UNWARRANTED CONCERNS
+
+Your news administrator may wonder if many people using tknewsbiff
+severely impact an NNTP server.  In fact, the impact is negligible
+even when the delay is very low.  To gather all the information it
+needs, tknewsbiff uses a single NNTP query - it just asks for the
+active file.  The NNTP server does no computation, formatting, etc, it
+just sends the file.  All the interesting processing happens locally
+in the tknewsbiff program itself.

+# Name: tkterm - terminal emulator using Expect and Tk text widget, v3.0
+# Author: Don Libes, July '94
+# Last updated: Mar '04
+
+# This is primarily for regression testing character-graphic applications.
+# You can certainly use it as a terminal emulator - however many features
+# in a real terminal emulator are not supported (although I'll probably
+# add some of them later).
+
+# A paper on the implementation: Libes, D., Automation and Testing of
+# Interactive Character Graphic Programs", Software - Practice &
+# Experience, John Wiley & Sons, West Sussex, England, Vol. 27(2),
+# p. 123-137, February 1997.
+
+###############################
+# Quick overview of this emulator
+###############################
+# Very good attributes:
+#   Understands both termcap and terminfo   
+#   Understands meta-key (zsh, emacs, etc work)
+#   Is fast
+#   Understands X selections
+#   Looks best with fixed-width font but doesn't require it
+#   Supports scrollbars
+# Good-enough-for-starters attributes:
+#   Understands one kind of standout mode (reverse video)
+# Should-be-fixed-soon attributes:
+#   Does not support resize
+# Probably-wont-be-fixed-soon attributes:
+#   Assumes only one terminal exists
+
+###############################################
+# To try out this package, just run it.  Using it in
+# your scripts is simple.  Here are directions:
+###############################################
+# 0) make sure Expect is linked into your Tk-based program (or vice versa)
+# 1) modify the variables/procedures below these comments appropriately
+# 2) source this file
+# 3) pack the text widget ($term) if you have so configured it (see
+#    "term_alone" below).  As distributed, it packs into . automatically.
+
+#############################################
+# Variables that must be initialized before using this:
+#############################################
+set rows 24		;# number of rows in term
+set rowsDumb $rows	;# number of rows in term when in dumb mode - this can
+			;# increase during runtime
+set cols 80		;# number of columns in term
+set term .t		;# name of text widget used by term
+set sb   .sb		;# name of scrollbar used by term in dumb mode
+set term_alone 1	;# if 1, directly pack term into .
+			;# else you must pack
+set termcap 1		;# if your applications use termcap
+set terminfo 1		;# if your applications use terminfo
+			;# (you can use both, but note that
+			;# starting terminfo is slow)
+set term_shell $env(SHELL) ;# program to run in term
+
+#############################################

+.TH UNBUFFER 1 "1 June 1994"
+.SH NAME
+unbuffer \- unbuffer output
+.SH SYNOPSIS
+.B unbuffer
+.I program
+
+.I args
+
+.SH INTRODUCTION
+.B unbuffer
+disables the output buffering that occurs when program output
+is redirected from non-interactive programs.
+For example, suppose you are watching the output from a fifo by running it
+through od and then more.  
+.nf
+
+	od -c /tmp/fifo | more
+
+.fi
+You will not see anything until a full page
+of output has been produced.
+
+You can disable this automatic buffering as follows:
+
+.nf
+
+	unbuffer od -c /tmp/fifo | more
+
+.fi
+Normally, unbuffer does not read from stdin.  This simplifies use of unbuffer in some situations.  To use unbuffer in a pipeline, use the -p flag.
+Example:
+.nf
+
+        process1 | unbuffer -p process2 | process3
+.fi
+.SH CAVEATS
+
+unbuffer -p may appear to work incorrectly if a process feeding input
+to unbuffer exits.  Consider:
+.nf
+        process1 | unbuffer -p process2 | process3
+
+.fi
+If process1 exits, process2 may not yet have finished.  It is
+impossible for unbuffer to know long to wait for process2 and process2
+may not ever finish, for example, if it is a filter.  For expediency,
+unbuffer simply exits when it encounters an EOF from either its input
+or process2.
+
+In order to have a version of unbuffer that worked in all situations,
+an oracle would be necessary.  If you want an application-specific
+solution, workarounds or hand-coded Expect may be more suitable.  For
+example, the following example shows how to allow grep to finish
+processing when the cat before it finishes first.  Using cat to feed
+grep would never require unbuffer in real life.  It is merely a
+placeholder for some imaginary process that may or may not finish.
+Similarly, the final cat at the end of the pipeline is also a
+placeholder for another process.
+
+.nf
+
+$ cat /tmp/abcdef.log | grep abc | cat
+abcdef
+xxxabc defxxx
+$ cat /tmp/abcdef.log | unbuffer grep abc | cat
+$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
+abcdef
+xxxabc defxxx
+$ 
+.fi
+.SH BUGS
+
+The man page is longer than the program.

+
+# Name: virterm - terminal emulator using Expect, v1.0, December, 1994
+# Author: Adrian Mariano <adrian@cam.cornell.edu>
+#
+# Derived from Done Libes' tkterm
+
+# This is a program for interacting with applications that use terminal
+# control sequences.  It is a subset of Don Libes' tkterm emulator
+# with a compatible interface so that programs can be written to work 
+# under both.  
+# 
+# Internally, it uses arrays instead of the Tk widget.  Nonetheless, this
+# code is not as fast as it should be.  I need an Expect profiler to go
+# any further.
+#
+# standout mode is not supported like it is in tkterm.  
+# the only terminal widget operation that is supported for the user
+# is the "get" operation.

+.TH XKIBITZ 1 "06 October 1994"
+.SH NAME
+xkibitz \- allow multiple people to interact in an xterm
+.SH SYNOPSIS
+.B xkibitz
+
+.I xkibitz-args
+ 
+.I program program-args...
+
+.br
+.SH INTRODUCTION
+.B xkibitz
+allows users in separate xterms to share one shell (or any program
+that runs in an xterm).  Uses include:
+.RS
+.TP 4
+\(bu
+A novice user can ask an expert user for help.  Using
+.BR xkibitz ,
+the expert can see what the user is doing, and offer advice or
+show how to do it right.
+.TP
+\(bu
+By running
+.B xkibitz
+and then starting a full-screen editor, people may carry out a
+conversation, retaining the ability to scroll backwards,
+save the entire conversation, or even edit it while in progress.
+.TP
+\(bu
+People can team up on games, document editing, or other cooperative
+tasks where each person has strengths and weaknesses that complement one
+another.
+.TP
+\(bu
+If you want to have a large number of people do an on-line code
+walk-through, you can sit two in front of each workstation, and then
+connect them all together while you everyone looks at code together
+in the editor.
+.SH USAGE
+To start
+.BR xkibitz ,
+one user (the master) runs xkibitz with no arguments.
+
+.B xkibitz
+starts a new shell (or another program, if given on the command
+line).  The user can interact normally with the shell, or 
+upon entering an escape (described when xkibitz starts) can add
+users to the interaction.
+
+To add users, enter "+ display" where display is the X display name.
+If there is no ":X.Y" in the display name, ":0.0" is assumed.
+The master user must have permission to access each display.
+Each display is assigned
+a tag \- a small integer which can be used to reference the display.
+
+To show the current tags and displays, enter "=".
+
+To drop a display, enter "- tag" where tag is the display's tag
+according to the "=" command.
+
+To return to the shared shell, enter "return".  Then the keystrokes of
+all users become the input of the shell.  Similarly, all users receive
+the output from the shell.
+
+To terminate
+.B xkibitz
+it suffices to terminate the shell itself.  For example, if any user
+types ^D (and the shell accepts this to be EOF), the shell terminates
+followed by
+.BR xkibitz .
+
+Normally, all characters are passed uninterpreted.  However, in the 
+escape dialogue the user talks directly to the
+.B xkibitz
+interpreter.  Any
+.BR Expect (1)
+or
+.BR Tcl (3)
+commands may also be given.
+Also, job control may be used while in the interpreter, to, for example,
+suspend or restart
+.BR xkibitz .
+
+Various processes
+can produce various effects.  For example, you can emulate a multi-way write(1)
+session with the command:
+
+	xkibitz sleep 1000000
+.PP
+.SH ARGUMENTS
+.B xkibitz
+understands a few special arguments
+which should appear before the
+.I program
+name (if given).
+Each argument should be separated by whitespace.
+If the arguments themselves takes arguments,
+these should also be separated by whitespace.
+
+.B \-escape
+sets the escape character.  The default escape character is ^.
+
+.B \-display
+adds a display much like the "+" command.  Multiple \-display flags
+can be given.  For example, to start up xkibitz with three additional
+displays:
+
+	xkibitz -display mercury -display fox -display dragon:1.0
+
+.SH CAVEATS
+Due to limitations in both X and UNIX, resize propagation is weak.
+
+When the master user resizes the xterm, all the other xterms are logically
+resized.  
+Unfortunately, xkibitz cannot force the physical xterm size to correspond
+with the logical xterm sizes.
+
+The other users are free to resize their xterm but their sizes are not
+propagated.  The master can check the logical sizes with the "=" command.
+
+Deducing the window size is a non-portable operation.  The code is known
+to work for recent versions of SunOS, AIX, Unicos, and HPUX.  Send back
+mods if you add support for anything else.
+.SH ENVIRONMENT
+The environment variable SHELL is used to determine and start a shell, if no
+other program is given on the command line.
+
+If the environment variable DISPLAY is defined, its value is used for the
+display name of the
+.B xkibitz
+master (the display with tag number 0). Otherwise this name remains empty.
+
+Additional arguments may be passed to new xterms through
+the environment variable XKIBITZ_XTERM_ARGS.
+For example, to create xterms
+with a scrollbar and a green pointer cursor:
+.nf
+
+	XKIBITZ_XTERM_ARGS="-sb -ms green"
+	export XKIBITZ_XTERM_ARGS
+
+.fi
+(this is for the Bourne shell - use whatever syntax is appropriate for your
+favorite shell). Any option can be given that is valid for the 
+.B xterm
+command, with the exception of
+.BR -display ,
+.B -geometry
+and
+.BI -S
+as those are set by
+.BR xkibitz .

+/* intMatch() accepts user keystrokes and returns one of MATCH,
+CANMATCH, or CANTMATCH.  These describe whether the keystrokes match a
+key sequence, and could or can't if more characters arrive.  The
+function assigns a matching keymap if there is a match or can-match.
+A matching keymap is assigned on can-match so we know whether to echo
+or not.
+
+intMatch is optimized (if you can call it that) towards a small
+number of key mappings, but still works well for large maps, since no
+function calls are made, and we stop as soon as there is a single-char
+mismatch, and go on to the next one.  A hash table or compiled DFA
+probably would not buy very much here for most maps.
+
+The basic idea of how this works is it does a smart sequential search.
+At each position of the input string, we attempt to match each of the
+keymaps.  If at least one matches, the first match is returned.
+
+If there is a CANMATCH and there are more keymaps to try, we continue
+trying.  If there are no more keymaps to try, we stop trying and
+return with an indication of the first keymap that can match.
+
+Note that I've hacked up the regexp pattern matcher in two ways.  One
+is to force the pattern to always be anchored at the front.  That way,
+it doesn't waste time attempting to match later in the string (before
+we're ready).  The other is to return can-match.

+ * because of operator precedence.)  The operand of some types of node is
+ * a literal string; for others, it is a node leading into a sub-FSM.  In

+ * For complete POSIX semantics, add POSIX_SEMANTICS.
+ *
+ * The code for %c, %x, and %X now follows the 1003.2 specification for
+ * the POSIX locale.
+ * This version ignores LOCALE information.
+ * It also doesn't worry about multi-byte characters.
+ * So there.
+ *
+ * This file is also shipped with GAWK (GNU Awk), gawk specific bits of
+ * code are included if GAWK is defined.

+.TH EXPECT 1 "29 December 1994"
+.SH NAME
+expect \- programmed dialogue with interactive programs, Version 5
+.SH SYNOPSIS
+.B expect
+
+.B \-dDinN
+
+
+.B \-c
+.I cmds
+
+
+
+.BR \-  f | b 
+
+.I cmdfile
+
+
+.I args
+
+.SH INTRODUCTION
+.B Expect
+is a program that "talks" to other interactive programs according to a
+script.  Following the script,
+.B Expect
+knows what can be expected from
+a program and what the correct response should be.  An interpreted
+language provides branching and high-level control structures to
+direct the dialogue.  In addition, the user can take control
+and interact directly when desired, afterward returning control to the
+script.
+.PP
+.B Expectk
+is a mixture of
+.B Expect
+and
+.BR Tk .
+It behaves just like
+.B Expect
+and
+.BR Tk 's
+.BR wish .
+.B Expect
+can also be used directly in C or C++ (that is, without Tcl).
+See libexpect(3).
+.PP
+The name "Expect" comes from the idea of
+.I send/expect
+sequences popularized
+by uucp, kermit and other modem control programs.
+However unlike uucp,
+.B Expect
+is generalized so that it can be run as a user-level command
+with any program and task in mind.
+.B Expect
+can actually talk to several programs at the same time.
+.PP
+For example, here are some things
+.B Expect
+can do:
+.RS
+.TP 4
+\(bu
+Cause your computer to dial you back,
+so that you can login without paying for the call.
+.TP
+\(bu
+Start a game (e.g., rogue) and if the optimal configuration doesn't appear,
+restart it (again and again) until it does,
+then hand over control to you.
+.TP
+\(bu
+Run fsck, and in response to its questions, answer "yes", "no" or give control back to you,
+based on predetermined criteria.
+.TP
+\(bu
+Connect to another network or BBS (e.g., MCI Mail, CompuServe) and
+automatically retrieve your mail so that it appears as if
+it was originally sent to your local system.
+.TP
+\(bu
+Carry environment variables, current directory,
+or any kind of information across rlogin, telnet, tip, su, chgrp, etc.
+.RE
+.PP
+There are a variety of reasons why the shell cannot perform these tasks.
+(Try, you'll see.)
+All are possible with
+.BR Expect .
+.PP
+In general,
+.B Expect
+is useful for running any program which requires
+interaction between the program and the user.
+All that is necessary is that the interaction can be characterized
+programmatically.
+.B Expect
+can also give the user back control
+(without halting the program being controlled) if desired.
+Similarly, the user can return control to the script at any time.
+.SH USAGE
+.B Expect
+reads
+.I cmdfile
+for a list of commands to execute.
+.B Expect
+may also be invoked implicitly on systems which support the #! notation
+by marking the script executable, and making the first line in your script:
+
+    #!/usr/local/bin/expect \-f
+
+Of course, the path must accurately describe where
+.B Expect
+lives.  /usr/local/bin is just an example.
+
+The
+.B \-c
+flag prefaces a command to be executed before any in the script.
+The command should be quoted to prevent being broken up by the shell.
+This option may be used multiple times.
+Multiple commands may be
+executed with a single
+.B \-c
+by separating them with semicolons.
+Commands are executed in the order they appear.  
+(When using Expectk, this option is specified as
+.BR \-command .)
+.PP
+The
+.B \-d
+flag enables some diagnostic output, which
+primarily reports internal activity of commands such as 
+.B expect
+and
+.BR interact .
+This flag has the same effect as "exp_internal 1" at the beginning of an Expect
+script, plus the version of
+.B Expect
+is printed.
+(The
+.B strace
+command is useful for tracing statements, and the
+.B trace
+command is useful for tracing variable assignments.)
+(When using Expectk, this option is specified as
+.BR \-diag .)
+.PP
+The
+.B \-D
+flag enables an interactive debugger.  An integer value should follow.
+The debugger will take control before the next Tcl procedure
+if the value is non-zero
+or if a ^C is pressed (or a breakpoint is hit, or other appropriate debugger
+command appears in the script).  See the README file or SEE ALSO (below)
+for more information on the debugger.
+(When using Expectk, this option is specified as
+.BR \-Debug .)
+.PP
+The
+.B \-f
+flag prefaces a file from which to read commands from.
+The flag itself is optional as it is only useful when using
+the #! notation (see above),
+so that other arguments may be supplied on the command line.
+(When using Expectk, this option is specified as
+.BR \-file .)
+.PP
+By default, the command file is read into memory and executed in its entirety.
+It is occasionally desirable to read files one line at a time.  For example,
+stdin is read this way.  In order to force arbitrary files to be handled this
+way, use the
+.B \-b
+flag.
+(When using Expectk, this option is specified as
+.BR \-buffer .)
+Note that stdio-buffering may still take place however this shouldn't cause
+problems when reading from a fifo or stdin.
+.PP
+If the string "\-" is supplied as a filename, standard input is read instead.
+(Use "./\-" to read from a file actually named "\-".)
+.PP
+The
+.B \-i
+flag causes
+.B Expect
+to interactively prompt for commands instead of reading
+them from a file.
+Prompting is terminated via the
+.B exit
+command or upon EOF.
+See
+.B interpreter
+(below) for more information.
+.B \-i
+is assumed if neither a command file nor
+.B \-c
+is used.
+(When using Expectk, this option is specified as
+.BR \-interactive .)
+.PP
+.B \-\-
+may be used to delimit the end of the options.  This is useful if
+you want to pass an option-like argument to your script without it being
+interpreted by
+.BR Expect .
+This can usefully be placed in the #! line to prevent any flag-like
+interpretation by Expect.  For example, the following will leave the
+original arguments (including the script name) in the variable
+.IR argv .
+
+    #!/usr/local/bin/expect \-\-
+
+Note that the usual getopt(3) and execve(2) conventions must be observed
+when adding arguments to the #! line.
+.PP
+The file $exp_library/expect.rc is sourced automatically if present, unless
+the
+.B \-N
+flag is used.  
+(When using Expectk, this option is specified as
+.BR \-NORC .)
+Immediately after this,
+the file ~/.expect.rc is sourced automatically, unless the
+.B \-n
+flag is used.  If the environment variable DOTDIR is defined,
+it is treated as a directory and .expect.rc is read from there.
+(When using Expectk, this option is specified as
+.BR \-norc .)
+This sourcing occurs only after executing any
+.B \-c
+flags.
+.PP
+.B \-v
+causes Expect to print its version number and exit.  (The corresponding flag
+in Expectk, which uses long flag names, is \-version.)
+.PP
+Optional
+.I args
+are constructed into a list and stored in the variable named
+.IR argv .
+.I argc
+is initialized to the length of argv.
+.PP
+.I argv0
+is defined to be the name of the script (or binary if no script is used).
+For example,
+the following prints out the name of the script and the first three arguments:
+.nf
+
+    send_user "$argv0 lrange $argv 0 2\\n"
+
+.fi
+.SH COMMANDS
+.B Expect
+uses
+.I Tcl
+(Tool Command Language).
+Tcl provides control flow (e.g., if, for, break),
+expression evaluation and several other features such as recursion,
+procedure definition, etc.
+Commands used here but not defined (e.g.,
+.BR set ,
+.BR if ,
+.BR exec )
+are Tcl commands (see tcl(3)).
+.B Expect
+supports additional commands, described below.
+Unless otherwise specified, commands return the empty string.
+.PP
+Commands are listed alphabetically so that they can be quickly located.
+However, new users may find it easier to start by reading the descriptions
+of
+.BR spawn ,
+.BR send ,
+.BR expect ,
+and
+.BR interact ,
+in that order.
+
+Note that the best introduction to the language (both Expect and Tcl)
+is provided in the book "Exploring Expect" (see SEE ALSO below).
+Examples are included in this man page but they are very limited since
+this man page is meant primarily as reference material.
+
+Note that in the text of this man page, "Expect" with an uppercase "E"
+refers to the
+.B Expect
+program while "expect" with a lower-case "e" refers to the
+.B expect
+command within the
+.B Expect
+program.)

+.BI close " -slave \-onexec 0|1 \-i spawn_id"
+closes the connection to the current process.
+Most interactive programs will detect EOF on their stdin and exit;
+thus
+.B close
+usually suffices to kill the process as well.
+The
+.B \-i
+flag declares the process to close corresponding to the named spawn_id.
+
+Both
+.B expect
+and
+.B interact
+will detect when the current process exits and implicitly do a
+.BR close .
+But if you kill the process by, say, "exec kill $pid",
+you will need to explicitly call
+.BR close .
+
+The
+.BR \-onexec
+flag determines whether the spawn id will be closed in any new spawned
+processes or if the process is overlayed.  To leave a spawn id open,
+use the value 0.  A non-zero integer value will force the spawn closed
+(the default) in any new processes.
+
+The 
+.B \-slave
+flag closes the slave associated with the spawn id.  (See "spawn -pty".)
+When the connection is closed, the slave is automatically closed as
+well if still open.
+
+No matter whether the connection is closed implicitly or explicitly,
+you should call
+.B wait
+to clear up the corresponding kernel process slot.
+.B close
+does not call
+.B wait
+since there is no guarantee that closing a process connection will cause
+it to exit.
+See
+.B wait
+below for more info.
+.TP
+.BI debug " -now 0|1"
+controls a Tcl debugger allowing you to step through statements, set
+breakpoints, etc.
+
+With no arguments, a 1 is returned if the debugger is not running, otherwise
+a 0 is returned.
+
+With a 1 argument, the debugger is started.  With a 0 argument, the
+debugger is stopped.  If a 1 argument is preceded by the
+.B \-now
+flag, the debugger is started immediately (i.e., in the middle of the
+.B debug
+command itself).  Otherwise, the debugger is started with the next
+Tcl statement.
+
+The
+.B debug
+command does not change any traps.  Compare this to starting Expect with the 
+.B -D
+flag (see above).
+
+See the README file or SEE ALSO (below)
+for more information on the debugger.
+.TP
+.B disconnect
+disconnects a forked process from the terminal.  It continues running in the
+background.  The process is given its own process group (if possible).
+Standard I/O is redirected to /dev/null.
+.IP
+The following fragment uses
+.B disconnect
+to continue running the script in the background.  
+.nf
+
+    if {fork!=0} exit
+    disconnect
+    . . .
+
+.fi
+The following script reads a password, and then runs a program
+every hour that demands a password each time it is run.  The script supplies
+the password so that you only have to type it once.
+(See the
+.B stty
+command which demonstrates how to turn off password echoing.)
+.nf
+
+    send_user "password?\\ "
+    expect_user -re "(.*)\\n"
+    for {} 1 {} {
+        if {fork!=0} {sleep 3600;continue}
+        disconnect
+        spawn priv_prog
+        expect Password:
+        send "$expect_out(1,string)\\r"
+        . . .
+        exit
+    }
+
+.fi
+An advantage to using
+.B disconnect
+over the shell asynchronous process feature (&) is that
+.B Expect
+can
+save the terminal parameters prior to disconnection, and then later
+apply them to new ptys.  With &,
+.B Expect
+does not have a chance
+to read the terminal's parameters since the terminal is already
+disconnected by the time
+.B Expect
+receives control.
+.TP
+.BI exit " \-opts status"
+causes
+.B Expect
+to exit or otherwise prepare to do so.
+
+The
+.B \-onexit
+flag causes the next argument to be used as an exit handler.
+Without an argument, the current exit handler is returned.
+
+The
+.B \-noexit
+flag causes
+.B Expect
+to prepare to exit but stop short of actually returning control to the
+operating system.  The user-defined exit handler is run as well as Expect's
+own internal handlers.
+No further Expect commands should be executed.
+This is useful if you are running Expect with other Tcl extensions.
+The current interpreter (and main window if in the Tk environment) remain
+so that other Tcl extensions can clean up.  If Expect's
+.B exit
+is called again (however this might occur), the handlers are not rerun.
+
+Upon exiting, 
+all connections to spawned processes are closed.  Closure will be detected
+as an EOF by spawned processes.
+.B exit
+takes no other actions beyond what the normal _exit(2) procedure does.
+Thus, spawned processes that do not check for EOF may continue to run.
+(A variety of conditions are important to determining, for example, what
+signals a spawned process will be sent, but these are system-dependent,
+typically documented under exit(3).)
+Spawned processes that continue to run will be inherited by init.
+
+.I status
+(or 0 if not specified) is returned as the exit status of
+.BR Expect .
+.B exit
+is implicitly executed if the end of the script is reached.
+.TP
+\fBexp_continue\fR -continue_timer
+The command
+.B exp_continue
+allows
+.B expect
+itself to continue
+executing rather than returning as it normally would. By
+default
+.B exp_continue
+resets the timeout timer. The
+.I -continue_timer
+flag prevents timer from being restarted. (See
+.B expect
+for more information.)
+.TP
+.BI exp_internal " \-f file value"
+causes further commands to send diagnostic information internal to
+.B Expect
+to stderr if
+.I value
+is non-zero.  This output is disabled if
+.I value
+is 0.  The diagnostic information includes every character received,
+and every attempt made to match the current output against the patterns.
+.IP
+If the optional
+.I file
+is supplied, all normal and debugging output is written to that file
+(regardless of the value of
+.IR value ).
+Any previous diagnostic output file is closed.
+
+The
+.B \-info
+flag causes exp_internal to return a description of the
+most recent non-info arguments given.
+.TP
+.BI exp_open " args \-i spawn_id"
+returns a Tcl file identifier that corresponds to the original spawn id.
+The file identifier can then be used as if it were opened by Tcl's
+.B open
+command.  (The spawn id should no longer be used.  A
+.B wait
+should not be executed.
+
+The
+.B \-leaveopen
+flag leaves the spawn id open for access through 
+Expect commands.  A
+.B wait
+must be executed on the spawn id.
+.TP
+.BI exp_pid " \-i spawn_id"
+returns the process id corresponding to the currently spawned process.
+If the
+.B \-i

+.TP
+.BI exp_version " \-exit version"
+is useful for assuring that the script is compatible with the current
+version of Expect.
+.IP
+With no arguments, the current version of
+.B Expect
+is returned.  This version
+may then be encoded in your script.  If you actually know that you are not
+using features of recent versions, you can specify an earlier version.
+.IP
+Versions consist of three numbers separated by dots.  First
+is the major number.  Scripts written for versions of
+.B Expect
+with a
+different major number will almost certainly not work.
+.B exp_version 
+returns an error if the major numbers do not match.
+.IP
+Second is the minor number.  Scripts written for a version with a
+greater minor number than the current version
+may depend upon some new feature and might not run.
+.B exp_version
+returns an error if the major numbers match, but the script minor number
+is greater than that of the running
+.BR Expect .
+.IP
+Third is a number that plays no part in the version comparison.
+However, it is incremented when the
+.B Expect
+software
+distribution is changed in any way, such as by additional documentation
+or optimization.  It is reset to 0 upon each new minor version.
+.IP
+With the
+.B \-exit
+flag,
+.B Expect
+prints an error and exits if the version is out of date.
+.TP
+.BI expect " \-opts pat1 body1 ... \-opts patn bodyn"
+waits until one of the patterns matches the output of a spawned process,
+a specified time period has passed, or an end-of-file is seen.
+If the final body is empty, it may be omitted.
+.IP
+Patterns from the most recent
+.B expect_before
+command are implicitly used before any other patterns.
+Patterns from the most recent
+.B expect_after
+command are implicitly used after any other patterns.
+.IP
+If the arguments to the entire
+.B expect
+statement require more than one line,
+all the arguments may be "braced" into one so as to avoid terminating each
+line with a backslash.  In this one case, the usual Tcl substitutions will
+occur despite the braces.
+.IP
+If a pattern is the keyword
+.BR eof ,
+the corresponding body is executed upon end-of-file.
+If a pattern is the keyword
+.BR timeout ,
+the corresponding body is executed upon timeout.  If no timeout keyword
+is used, an implicit null action is executed upon timeout.
+The default timeout period is 10 seconds but may be set, for example to 30,
+by the command "set timeout 30".  An infinite timeout may be designated
+by the value \-1.
+If a pattern is the keyword
+.BR default ,
+the corresponding body is executed upon either timeout or end-of-file.
+.IP
+If a pattern matches, then the corresponding body is executed.
+.B expect
+returns the result of the body (or the empty string if no pattern matched).
+In the event that multiple patterns match, the one appearing first is
+used to select a body.
+.IP
+Each time new output arrives, it is compared to each pattern in the order
+they are listed.  Thus, you may test for absence of a match by making
+the last pattern something guaranteed to appear, such as a prompt.
+In situations where there is no prompt, you must use
+.B timeout
+(just like you would if you were interacting manually).
+.IP
+Patterns are specified in three ways.  By default, 
+patterns are specified as with Tcl's
+.B string match
+command.  (Such patterns are also similar to C-shell regular expressions
+usually referred to as "glob" patterns).  The
+.B \-gl
+flag may may
+be used to protect patterns that might otherwise match
+.B expect
+flags from doing so.
+Any pattern beginning with a "-" should be protected this way.  (All strings
+starting with "-" are reserved for future options.)
+
+.IP
+For example, the following fragment looks for a successful login.
+(Note that
+.B abort
+is presumed to be a procedure defined elsewhere in the script.)
+.nf
+
+.ta \w'      expect 'u +\w'invalid password    'u
+    expect {
+        busy               {puts busy\\n ; exp_continue}
+        failed             abort
+        "invalid password" abort
+        timeout            abort
+        connected
+    }
+
+.fi
+Quotes are necessary on the fourth pattern since it contains a space, which
+would otherwise separate the pattern from the action.
+Patterns with the same action (such as the 3rd and 4th) require listing the
+actions again.  This can be avoid by using regexp-style patterns (see below).
+More information on forming glob-style patterns can be found in the Tcl manual.
+.IP
+Regexp-style patterns follow the syntax defined by Tcl's
+.B regexp
+(short for "regular expression") command.
+regexp patterns are introduced with the flag
+.BR \-re .
+The previous example can be rewritten using a regexp as:
+.nf
+
+.ta \w'      expect 'u +\w'connected    'u
+    expect {
+        busy       {puts busy\\n ; exp_continue}
+        \-re "failed|invalid password" abort
+        timeout    abort
+        connected
+    }
+
+.fi
+Both types of patterns are "unanchored".  This means that patterns
+do not have to match the entire string, but can begin and end the
+match anywhere in the string (as long as everything else matches).
+Use ^ to match the beginning of a string, and $ to match the end.
+Note that if you do not wait for the end of a string, your responses
+can easily end up in the middle of the string as they are echoed from
+the spawned process.  While still producing correct results, the output
+can look unnatural.  Thus, use of $ is encouraged if you can exactly
+describe the characters at the end of a string.
+
+Note that in many editors, the ^ and $ match the beginning and end of
+lines respectively. However, because expect is not line oriented,
+these characters match the beginning and end of the data (as opposed
+to lines) currently in the expect matching buffer.  (Also, see the
+note below on "system indigestion.")
+
+The
+.B \-ex
+flag causes the pattern to be matched as an "exact" string.  No
+interpretation of *, ^, etc is made (although the usual Tcl
+conventions must still be observed).
+Exact patterns are always unanchored.
+
+.IP
+The
+.B \-nocase
+flag causes uppercase characters of the output to compare as if they were
+lowercase characters.  The pattern is not affected.
+.IP
+While reading output,
+more than 2000 bytes can force earlier bytes to be "forgotten".
+This may be changed with the function
+.BR match_max .
+(Note that excessively large values can slow down the pattern matcher.)
+If
+.I patlist
+is
+.BR full_buffer ,
+the corresponding body is executed if
+.I match_max
+bytes have been received and no other patterns have matched.
+Whether or not the
+.B full_buffer
+keyword is used, the forgotten characters are written to
+expect_out(buffer).
+
+If
+.I patlist
+is the keyword
+.BR null ,
+and nulls are allowed (via the
+.B remove_nulls
+command), the corresponding body is executed if a single ASCII
+0 is matched.
+It is not possible to
+match 0 bytes via glob or regexp patterns.
+
+Upon matching a pattern (or eof or full_buffer),
+any matching and previously unmatched output is saved in the variable
+.IR expect_out(buffer) .
+Up to 9 regexp substring matches are saved in the variables
+.I expect_out(1,string)
+through
+.IR expect_out(9,string) .
+If the
+.B -indices
+flag is used before a pattern,
+the starting and ending indices (in a form suitable for
+.BR lrange )
+of the
+10 strings are stored in the variables
+.I expect_out(X,start)
+and
+.I expect_out(X,end)
+where X is a digit, corresponds to the substring position in the buffer.
+0 refers to strings which matched the entire pattern
+and is generated for glob patterns as well as regexp patterns.
+For example, if a process has produced output of "abcdefgh\\n", the result of:
+.nf
+
+    expect "cd"
+
+.fi
+is as if the following statements had executed:
+.nf
+
+    set expect_out(0,string) cd
+    set expect_out(buffer) abcd
+
+.fi
+and "efgh\\n" is left in the output buffer.
+If a process produced the output "abbbcabkkkka\\n", the result of:
+.nf
+
+    expect \-indices \-re "b(b*).*(k+)"
+
+.fi
+is as if the following statements had executed:
+.nf
+
+    set expect_out(0,start) 1
+    set expect_out(0,end) 10
+    set expect_out(0,string) bbbcabkkkk
+    set expect_out(1,start) 2
+    set expect_out(1,end) 3
+    set expect_out(1,string) bb
+    set expect_out(2,start) 10
+    set expect_out(2,end) 10
+    set expect_out(2,string) k
+    set expect_out(buffer) abbbcabkkkk
+
+.fi
+and "a\\n" is left in the output buffer.  The pattern "*" (and -re ".*") will
+flush the output buffer without reading any more output from the
+process.
+.IP
+Normally, the matched output is discarded from Expect's internal buffers.
+This may be prevented by prefixing a pattern with the
+.B \-notransfer
+flag.  This flag is especially useful in experimenting (and can be
+abbreviated to "-not" for convenience while experimenting).
+
+The spawn id associated with the matching output (or eof or
+full_buffer) is stored in
+.IR expect_out(spawn_id) .
+
+The
+.B \-timeout
+flag causes the current expect command to use the following value
+as a timeout instead of using the value of the timeout variable.
+
+By default, 
+patterns are matched against output from the current process, however the
+.B \-i
+flag declares the output from the named spawn_id list be matched against
+any following patterns (up to the next
+.BR \-i ).
+The spawn_id list should either be a whitespace separated list of spawn_ids
+or a variable referring to such a list of spawn_ids.
+
+For example, the following example waits for
+"connected" from the current process, or "busy", "failed" or "invalid
+password" from the spawn_id named by $proc2.
+.nf
+
+    expect {
+        \-i $proc2 busy {puts busy\\n ; exp_continue}
+        \-re "failed|invalid password" abort
+        timeout abort
+        connected
+    }
+
+.fi
+The value of the global variable
+.I any_spawn_id
+may be used to match patterns to any spawn_ids that are named
+with all other
+.B \-i
+flags in the current
+.B expect
+command.
+The spawn_id from a
+.B \-i
+flag with no associated pattern (i.e., followed immediately
+by another
+.BR \-i )
+is made available to any other patterns
+in the same
+.B expect
+command associated with
+.I any_spawn_id.
+
+The
+.B \-i
+flag may also name a global variable in which case the variable is read
+for a list of spawn ids.  The variable is reread whenever it changes.
+This provides a way of changing the I/O source while the command is in
+execution.  Spawn ids provided this way are called "indirect" spawn ids.
+
+Actions such as
+.B break
+and
+.B continue
+cause control structures (i.e.,
+.BR for ,
+.BR proc )
+to behave in the usual way.
+The command
+.B exp_continue
+allows
+.B expect
+itself to continue
+executing rather than returning as it normally would.
+.IP
+This is useful for avoiding explicit loops or repeated expect statements.
+The following example is part of a fragment to automate rlogin.  The
+.B exp_continue
+avoids having to write a second
+.B expect
+statement (to look for the prompt again) if the rlogin prompts for a password.
+.nf
+
+    expect {
+        Password: {
+            stty -echo
+            send_user "password (for $user) on $host: "
+            expect_user -re "(.*)\\n"
+            send_user "\\n"
+            send "$expect_out(1,string)\\r"
+            stty echo
+            exp_continue
+        } incorrect {
+            send_user "invalid password or account\\n"
+            exit
+        } timeout {
+            send_user "connection to $host timed out\\n"
+            exit

+            send_user \\
+                "connection to host failed: $expect_out(buffer)"
+            exit
+        } -re $prompt
+    }
+
+.fi
+For example, the following fragment might help a user guide
+an interaction that is already totally automated.  In this case, the terminal
+is put into raw mode.  If the user presses "+", a variable is incremented.
+If "p" is pressed, several returns are sent to the process,
+perhaps to poke it in some way, and "i" lets the user interact with the
+process, effectively stealing away control from the script.
+In each case, the
+.B exp_continue
+allows the current
+.B expect
+to continue pattern matching after executing the
+current action.

+of the

+
+Unless overridden by a

+patterns match against the spawn id defined at the time that the 
+.B expect_before
+command was executed (not when its pattern is matched).
+
+The \-info flag causes
+.B expect_before
+to return the current specifications of what patterns it will match.
+By default, it reports on the current spawn id.  An optional spawn id specification may be given for information on that spawn id.  For example
+.nf
+
+    expect_before -info -i $proc

+At most one spawn id specification may be given.  The flag \-indirect
+suppresses direct spawn ids that come only from indirect specifications.

+.IP
+In string-body pairs, strings are matched in the order they are listed
+as arguments.  Strings that partially match are not sent to the
+current process in anticipation of the remainder coming.  If
+characters are then entered such that there can no longer possibly be
+a match, only the part of the string will be sent to the process that cannot
+possibly begin another match.  Thus, strings that are substrings of
+partial matches can match later, if the original strings that was attempting
+to be match ultimately fails.
+.IP
+By default, string matching is exact with no wild cards.  (In contrast,
+the
+.B expect
+command uses glob-style patterns by default.)  The
+.B \-ex
+flag may be used to protect patterns that might otherwise match
+.B interact
+flags from doing so.
+Any pattern beginning with a "-" should be protected this way.    (All strings
+starting with "-" are reserved for future options.)
+
+The
+.B \-re
+flag forces the string to be interpreted as a regexp-style pattern.  In this
+case, matching substrings are stored in the variable
+.I interact_out
+similarly to the way
+.B expect
+stores its output in the variable
+.BR expect_out .
+The
+.B \-indices
+flag is similarly supported.
+
+The pattern
+.B eof
+introduces an action that is 
+executed upon end-of-file.  A separate
+.B eof
+pattern may also follow the
+.B \-output
+flag in which case it is matched if an eof is detected while writing output.
+The default
+.B eof
+action is "return", so that
+.B interact
+simply returns upon any EOF.
+
+The pattern
+.B timeout
+introduces a timeout (in seconds) and action that is executed
+after no characters have been read for a given time.
+The
+.B timeout
+pattern applies to the most recently specified process.
+There is no default timeout.
+The special variable "timeout" (used by the
+.B expect
+command) has no affect on this timeout.
+
+For example, the following statement could be used to autologout users who have
+not typed anything for an hour but who still get frequent system
+messages:
+.nf
+
+    interact -input $user_spawn_id timeout 3600 return -output \\
+        $spawn_id 
+
+.fi
+
+If the pattern is the keyword
+.BR null ,
+and nulls are allowed (via the
+.B remove_nulls
+command), the corresponding body is executed if a single ASCII
+0 is matched.
+It is not possible to
+match 0 bytes via glob or regexp patterns.
+
+Prefacing a pattern with the flag
+.B \-iwrite
+causes the variable
+.I interact_out(spawn_id)
+to be set to the spawn_id which matched the pattern
+(or eof).
+
+Actions such as
+.B break
+and
+.B continue
+cause control structures (i.e.,
+.BR for ,
+.BR proc )
+to behave in the usual way.
+However
+.B return
+causes interact to return to its caller, while
+.B inter_return
+causes
+.B interact
+to cause a return in its caller.  For example, if "proc foo" called
+.B interact
+which then executed the action
+.BR inter_return ,
+.B proc foo
+would return.  (This means that if
+.B interact
+calls
+.B interpreter
+interactively typing
+.B return
+will cause the interact to continue, while
+.B inter_return
+will cause the interact to return to its caller.)
+.IP
+During
+.BR interact ,
+raw mode is used so that all characters may be passed to the current process.
+If the current process does not catch job control signals,
+it will stop if sent a stop signal (by default ^Z).
+To restart it, send a continue signal (such as by "kill \-CONT <pid>").
+If you really want to send a SIGSTOP to such a process (by ^Z),
+consider spawning csh first and then running your program.
+On the other hand, if you want to send a SIGSTOP to
+.B Expect
+itself, first call interpreter (perhaps by using an escape character), and then press ^Z.
+.IP
+String-body pairs can be used as a shorthand for avoiding having
+to enter the interpreter and execute commands interactively.  The previous
+terminal mode is used while the body of a string-body pair is being executed.
+.IP
+For speed, actions execute in raw mode by default.  The
+.B \-reset
+flag resets the terminal to the mode it had before
+.B interact
+was executed (invariably, cooked mode).
+Note that characters entered when the mode is being switched may be lost
+(an unfortunate feature of the terminal driver on some systems).
+The only reason to use
+.B \-reset
+is if your action
+depends on running in cooked mode.
+.IP
+The
+.B \-echo
+flag sends characters that match the following pattern back to the process
+that generated them as each character is read.  This may be useful
+when the user needs to see feedback from partially typed patterns.
+.IP
+If a pattern is being echoed but eventually fails to match,
+the characters are sent to the spawned process.  If the spawned
+process then echoes them, the user will see the characters twice.
+.B \-echo
+is probably only appropriate in situations where the user is
+unlikely to not complete the pattern.  For example, the following
+excerpt is from rftp, the recursive-ftp script, where the user is
+prompted to enter ~g, ~p, or ~l, to get, put, or list the current
+directory recursively.  These are so far away from the normal ftp
+commands, that the user is unlikely to type ~ followed by anything
+else, except mistakenly, in which case, they'll probably just ignore
+the result anyway.
+.nf
+
+    interact {
+        -echo ~g {getcurdirectory 1}

+    }
+
+.fi
+The
+.B \-nobuffer
+flag sends characters that match the following pattern on to
+the output process as characters are read.
+
+This is useful when you wish to let a program echo back the pattern.
+For example, the following might be used to monitor where a person is
+dialing (a Hayes-style modem).  Each time "atd" is seen the script
+logs the rest of the line.
+.nf
+
+    proc lognumber {} {
+        interact -nobuffer -re "(.*)\\r" return

+During
+.BR interact ,
+previous use of
+.B log_user
+is ignored.  In particular,
+.B interact
+will force its output to be logged (sent to the standard output)
+since it is presumed the user doesn't wish to interact blindly.
+.IP
+The
+.B \-o
+flag causes any following key-body pairs to be applied to the output of
+the current process.
+This can be useful, for example, when dealing with hosts that
+send unwanted characters during a telnet session.  
+.IP
+By default, 
+.B interact
+expects the user to be writing stdin and reading stdout of the
+.B Expect
+process
+itself.
+The
+.B \-u
+flag (for "user") makes
+.B interact
+look for the user as the process named by its argument
+(which must be a spawned id).  
+.IP
+This allows two unrelated processes to be joined
+together without using an explicit loop.  To aid in debugging, Expect
+diagnostics always go to stderr (or stdout for certain logging and
+debugging information).  For the same reason, the
+.B interpreter
+command will read interactively from stdin.
+.IP
+For example, the following fragment creates a login process.
+Then it dials the user (not shown), and finally connects the two together.
+Of course, any process may be substituted for login.
+A shell, for example, would allow the user to work without supplying an
+account and password.
+.nf
+
+    spawn login
+    set login $spawn_id
+    spawn tip modem
+    # dial back out to user
+    # connect user to login
+    interact \-u $login
+
+.fi
+To send output to multiple processes, list each spawn id list prefaced by a
+.B \-output
+flag.  Input for a group of output spawn ids may be determined
+by a spawn id list prefaced by a
+.B \-input
+flag.  (Both
+.B \-input
+and
+.B \-output
+may take lists in the same form as the
+.B \-i
+flag in the
+.B expect
+command, except that any_spawn_id is not meaningful in
+.BR interact .)
+All following flags and
+strings (or patterns) apply to this input until another -input flag appears.
+If no
+.B \-input
+appears,
+.B \-output
+implies "\-input $user_spawn_id \-output".
+(Similarly, with patterns that do not have
+.BR \-input .)
+If one
+.B \-input
+is specified, it overrides $user_spawn_id.  If a second
+.B \-input
+is specified,
+it overrides $spawn_id.  Additional
+.B \-input
+flags may be specified.
+
+The two implied input processes default to having their outputs specified as
+$spawn_id and $user_spawn_id (in reverse).  
+If a
+.B \-input
+flag appears
+with no
+.B \-output
+flag, characters from that process are discarded.
+
+The
+.B \-i
+flag introduces a replacement for the current spawn_id when no
+other
+.B \-input
+or
+.B \-output
+flags are used.  A \-i flag implies a \-o flag.
+
+It is possible to change the processes that are being interacted with
+by using indirect spawn ids.  (Indirect spawn ids are described in the
+section on the expect command.)  Indirect spawn ids may be specified
+with the -i, -u, -input, or -output flags.

+Sends

+
+    send "hello world\\r"
+

+sends the characters, h e l l o <blank> w o r l d <return> to the 
+current process.  
+(Tcl includes a printf-like command (called
+.BR format )
+which can build arbitrarily complex strings.)
+.IP
+Characters are sent immediately although programs with line-buffered input
+will not read the characters until a return character is sent.  A return
+character is denoted "\\r".
+
+The
+.B \-\-
+flag forces the next argument to be interpreted as a string rather than a flag.
+Any string can be preceded by "\-\-" whether or not it actually looks
+like a flag.  This provides a reliable mechanism to specify variable strings
+without being tripped up by those that accidentally look like flags.
+(All strings starting with "-" are reserved for future options.)
+
+The
+.B \-i
+flag declares that the string be sent to the named spawn_id.
+If the spawn_id is
+.IR user_spawn_id ,
+and the terminal is in raw mode, newlines in the string are translated
+to return-newline
+sequences so that they appear as if the terminal was in cooked mode.
+The
+.B \-raw
+flag disables this translation.
+
+The
+.BR \-null
+flag sends null characters (0 bytes).  By default, one null is sent.
+An integer may follow the
+.BR \-null
+to indicate how many nulls to send.
+
+The
+.B \-break
+flag generates a break condition.  This only makes sense if the spawn
+id refers to a tty device opened via "spawn -open".  If you have
+spawned a process such as tip, you should use tip's convention for
+generating a break.
+
+The
+.B \-s
+flag forces output to be sent "slowly", thus avoid the common situation
+where a computer outtypes an input buffer that was designed for a
+human who would never outtype the same buffer.  This output is
+controlled by the value of the variable "send_slow" which takes a two
+element list.  The first element is an integer that describes the
+number of bytes to send atomically.  The second element is a real
+number that describes the number of seconds by which the atomic sends
+must be separated.  For example, "set send_slow {10 .001}" would force
+"send \-s" to send strings with 1 millisecond in between each 10
+characters sent.
+
+The
+.B \-h
+flag forces output to be sent (somewhat) like a human actually typing.
+Human-like delays appear between the characters.  (The algorithm is
+based upon a Weibull distribution, with modifications to suit this
+particular application.)  This output is controlled by the value of
+the variable "send_human" which takes a five element list.  The first
+two elements are average interarrival time of characters in seconds.
+The first is used by default.  The second is used at word endings, to
+simulate the subtle pauses that occasionally occur at such
+transitions.  The third parameter is a measure of variability where .1
+is quite variable, 1 is reasonably variable, and 10 is quite
+invariable.  The extremes are 0 to infinity.  The last two parameters
+are, respectively, a minimum and maximum interarrival time.
+The minimum and maximum are used last and "clip" the final time.
+The ultimate average can be quite different from the given average
+if the minimum and maximum clip enough values.
+
+As an
+example, the following command emulates a fast and
+consistent typist:
+.nf
+
+    set send_human {.1 .3 1 .05 2}
+    send \-h "I'm hungry.  Let's do lunch."
+
+.fi
+while the following might be more suitable after a hangover:
+.nf
+
+    set send_human {.4 .4 .2 .5 100}
+    send \-h "Goodd party lash night!"
+
+.fi
+Note that errors are not simulated, although you can set up error
+correction situations yourself by embedding mistakes and corrections
+in a send argument.
+
+The flags for sending null characters, for sending breaks, for forcing slow
+output and for human-style output are mutually exclusive. Only the one
+specified last will be used. Furthermore, no
+.I string
+argument can be specified with the flags for sending null characters or breaks.
+
+It is a good idea to precede the first
+.B send
+to a process by an
+.BR expect .
+.B expect
+will wait for the process to start, while
+.B send
+cannot.
+In particular, if the first
+.B send
+completes before the process starts running,
+you run the risk of having your data ignored.
+In situations where interactive programs offer no initial prompt,
+you can precede
+.B send
+by a delay as in:
+.nf
+
+    # To avoid giving hackers hints on how to break in,
+    # this system does not prompt for an external password.
+    # Wait for 5 seconds for exec to complete
+    spawn telnet very.secure.gov

+the processes to which these ptys are attached, your only recourse may
+be to reboot.
+
+If
+.I program
+cannot be spawned successfully because exec(2) fails (e.g. when
+.I program
+doesn't exist), an error message will be returned by the next
+.B interact
+or
+.B expect
+command as if
+.I program
+had run and produced the error message as output.
+This behavior is a natural consequence of the implementation of
+.BR spawn .
+Internally, spawn forks, after which the spawned process has no
+way to communicate with the original
+.B Expect
+process except by communication
+via the spawn_id.
+
+The
+.B \-open
+flag causes the next argument to be interpreted as a Tcl file identifier
+(i.e., returned by
+.BR open .)
+The spawn id can then be used as if it were a spawned process.  (The file
+identifier should no longer be used.)
+This lets you treat raw devices, files, and
+pipelines as spawned processes without using a pty.  0 is returned to
+indicate there is no associated process.  When the connection to
+the spawned process is closed, so is the Tcl file identifier.
+The
+.B \-leaveopen
+flag is similar to
+.B \-open
+except that
+.B \-leaveopen
+causes the file identifier to be left open even after the spawn id is closed.
+
+The
+.B \-pty
+flag causes a pty to be opened but no process spawned.  0 is returned
+to indicate there is no associated process.  Spawn_id is set as usual.
+
+The variable
+.I spawn_out(slave,fd)
+is set to a file identifier corresponding to the pty slave.
+It can be closed using "close -slave".
+
+The
+.B \-ignore
+flag names a signal to be ignored in the spawned process.
+Otherwise, signals get the default behavior.
+Signals are named as in the
+.B trap
+command, except that each signal requires a separate flag.
+.TP
+.BI strace " level"
+causes following statements to be printed before being executed.
+(Tcl's trace command traces variables.)
+.I level
+indicates how far down in the call stack to trace.
+For example,
+the following command runs
+.B Expect
+while tracing the first 4 levels of calls,
+but none below that.
+.nf
+
+    expect \-c "strace 4" script.exp
+
+.fi
+
+The
+.B -info
+flag causes strace to return a description of the
+most recent non-info arguments given.
+.TP
+.BI stty " args"
+changes terminal modes similarly to the external stty command.
+
+By default, the controlling terminal is accessed.  Other terminals can
+be accessed by appending "< /dev/tty..." to the command.  (Note that
+the arguments should not be grouped into a single argument.)
+
+Requests for status return it as the result of the command.  If no status
+is requested and the controlling terminal is accessed, the previous
+status of the raw and echo attributes are returned in a form which can
+later be used by the command.
+
+For example, the arguments
+.B raw
+or
+.B \-cooked
+put the terminal into raw mode.
+The arguments
+.B \-raw
+or
+.B cooked
+put the terminal into cooked mode.
+The arguments
+.B echo
+and
+.B \-echo
+put the terminal into echo and noecho mode respectively.
+.IP
+The following example illustrates how to temporarily disable echoing.
+This could be used in otherwise-automatic
+scripts to avoid embedding passwords in them.
+(See more discussion on this under EXPECT HINTS below.)
+.nf
+
+    stty \-echo
+    send_user "Password: "
+    expect_user -re "(.*)\\n"
+    set password $expect_out(1,string)
+    stty echo
+
+.fi
+.TP
+.BI system " args"
+gives
+.I args
+to sh(1) as input,
+just as if it had been typed as a command from a terminal.
+.B Expect
+waits until the shell terminates.
+The return status from sh is handled the same way that
+.B exec
+handles its return status.
+.IP
+In contrast to
+.B exec
+which redirects stdin and stdout to the script,
+.B system
+performs no redirection
+(other than that indicated by the string itself).
+Thus, it is possible to use programs which must talk directly to /dev/tty.
+For the same reason, the results of
+.B system
+are not recorded in the log.
+.TP
+.BI timestamp " args"
+returns a timestamp.
+With no arguments, the number of
+seconds since the epoch is returned.
+
+The
+.B \-format
+flag introduces a string which is returned but with 
+substitutions made according to the
+POSIX rules for strftime.  For example %a is replaced by an abbreviated
+weekday name (i.e., Sat).  Others are:
+.nf
+    %a      abbreviated weekday name
+    %A      full weekday name
+    %b      abbreviated month name
+    %B      full month name
+    %c      date-time as in: Wed Oct  6 11:45:56 1993
+    %d      day of the month (01-31)
+    %H      hour (00-23)
+    %I      hour (01-12)
+    %j      day (001-366)
+    %m      month (01-12)
+    %M      minute (00-59)
+    %p      am or pm
+    %S      second (00-61)
+    %u      day (1-7, Monday is first day of week)
+    %U      week (00-53, first Sunday is first day of week one)
+    %V      week (01-53, ISO 8601 style)
+    %w      day (0-6)
+    %W      week (00-53, first Monday is first day of week one)
+    %x      date-time as in: Wed Oct  6 1993
+    %X      time as in: 23:59:59
+    %y      year (00-99)
+    %Y      year as in: 1993
+    %Z      timezone (or nothing if not determinable)
+    %%      a bare percent sign
+
+.fi
+Other % specifications are undefined.  Other characters will be passed
+through untouched.  Only the C locale is supported.
+
+The
+.B \-seconds
+flag introduces a number of seconds since the epoch to be used as a source
+from which to format.  Otherwise, the current time is used.
+
+The
+.B \-gmt
+flag forces timestamp output to use the GMT timezone.  With no flag,
+the local timezone is used.
+.TP
+.BI trap " command signals"
+causes the given 
+.I command
+to be executed upon future receipt of any of the given signals.
+The command is executed in the global scope.
+If
+.I command
+is absent, the signal action is returned.
+If
+.I command 
+is the string SIG_IGN, the signals are ignored.
+If
+.I command
+is the string SIG_DFL, the signals are result to the system default.
+.I signals
+is either a single signal or a list of signals.  Signals may be specified
+numerically or symbolically as per signal(3).  The "SIG" prefix may be omitted.
+
+With no arguments (or the argument \-number),
+.B trap
+returns the signal number of the trap command currently being executed.
+
+The
+.B \-code
+flag uses the return code of the command in place of whatever code Tcl
+was about to return when the command originally started running.
+
+The
+.B \-interp
+flag causes the command to be evaluated using the interpreter
+active at the time the command started running
+rather than when the trap was declared.
+
+The
+.B \-name
+flag causes the
+.B trap
+command to return the signal name of the trap command currently being executed.
+
+The
+.B \-max
+flag causes the
+.B trap
+command to return the largest signal number that can be set.
+
+For example, the command "trap {send_user "Ouch!"} SIGINT" will print "Ouch!"
+each time the user presses ^C.
+
+By default, SIGINT (which can usually be generated by pressing ^C) and 
+SIGTERM cause Expect to exit.  This is due to the following trap, created
+by default when Expect starts.
+.nf
+
+    trap exit {SIGINT SIGTERM}
+
+.fi
+If you use the -D flag to start the debugger, SIGINT is redefined
+to start the interactive debugger.  This is due to the following trap:
+.nf
+
+    trap {exp_debug 1} SIGINT
+
+.fi
+The debugger trap can be changed by setting the environment variable
+EXPECT_DEBUG_INIT to a new trap command.  
+
+You can, of course, override both of these just by adding trap
+commands to your script.  In particular, if you have your own "trap
+exit SIGINT", this will override the debugger trap.  This is useful
+if you want to prevent users from getting to the debugger at all.
+
+If you want to define your own trap on SIGINT but still trap to the
+debugger when it is running, use:
+.nf
+
+    if {!exp_debug} {trap mystuff SIGINT}
+
+.fi
+Alternatively, you can trap to the debugger using some other signal.
+
+.B trap
+will not let you override the action for SIGALRM as this is used internally
+to
+.BR Expect .
+The disconnect command sets SIGALRM to SIG_IGN (ignore).  You can reenable
+this as long as you disable it during subsequent spawn commands.
+
+See signal(3) for more info.
+.TP
+.BI wait " args"
+delays until a spawned process (or
+the current process if none is named) terminates.
+.IP
+.B wait
+normally returns a list of four integers.
+The first integer is the pid of the process that was waited upon.
+The second integer is the corresponding spawn id.
+The third integer is -1 if an operating system error occurred, or 0 otherwise.
+If the third integer was 0, the fourth integer is the status returned by
+the spawned process.  If the third integer was -1, the fourth integer is
+the value of errno set by the operating system.  The global variable
+errorCode is also set.
+
+Additional elements may appear at the end of the return value from
+.BR wait .
+An optional fifth element identifies a class of information.
+Currently, the only possible value for this element is CHILDKILLED in
+which case the next two values are the C-style signal name and a short
+textual description.
+.IP
+The
+.B \-i
+flag declares the process to wait corresponding to the named spawn_id
+(NOT the process id).
+Inside a SIGCHLD handler,
+it is possible to wait for any spawned process by using the spawn id -1.
+
+The
+.B \-nowait
+flag causes the wait to return immediately with the indication of a
+successful wait.  When the process exits (later), it will automatically
+disappear without the need for an explicit wait.
+
+The
+.B wait
+command may also be used wait for a forked process using the arguments
+"-i -1".  Unlike its use with spawned processes, this command can be
+executed at any time.  There is no control over which process is
+reaped.  However, the return value can be checked for the process id.
+
+.SH LIBRARIES
+Expect automatically knows about two built-in libraries for Expect scripts.
+These are defined by the directories named in the variables
+exp_library and exp_exec_library.  Both are meant to contain utility
+files that can be used by other scripts.
+
+exp_library contains architecture-independent files.  exp_exec_library
+contains architecture-dependent files.  Depending on your system, both
+directories may be totally empty.  The existence of the file
+$exp_exec_library/cat-buffers describes whether your /bin/cat buffers
+by default.
+.SH PRETTY-PRINTING
+A vgrind definition is available for pretty-printing
+.B Expect
+scripts.
+Assuming the vgrind definition supplied with the
+.B Expect
+distribution is
+correctly installed, you can use it as:
+.nf
+
+    vgrind \-lexpect file
+
+.fi
+.SH EXAMPLES
+It many not be apparent how to put everything together that the man page
+describes.  I encourage you to read and try out the examples in
+the example directory of the
+.B Expect
+distribution.
+Some of them are real programs.  Others are simply illustrative
+of certain techniques, and of course, a couple are just quick hacks.
+The INSTALL file has a quick overview of these programs.
+.PP
+The
+.B Expect
+papers (see SEE ALSO) are also useful.  While some papers
+use syntax corresponding to earlier versions of Expect, the accompanying
+rationales are still valid and go into a lot more detail than this
+man page.
+.SH CAVEATS
+Extensions may collide with Expect's command names.  For example, 
+.B send
+is defined by Tk for an entirely different purpose.
+For this reason, most of the
+.B Expect
+commands are also available as "exp_XXXX".
+Commands and variables beginning with "exp", "inter", "spawn",
+and "timeout" do not have aliases.
+Use the extended command names if you need this compatibility between environments.
+
+.B Expect
+takes a rather liberal view of scoping.
+In particular, variables read by commands specific to the
+.B Expect
+program will be sought first from the local scope, and if not found, in the
+global scope.  For example, this
+obviates the need to place "global timeout" in every
+procedure you write that uses
+.BR expect .
+On the other hand, variables written are always in the local scope (unless
+a "global" command has been issued).  The most common problem this causes
+is when spawn is executed in a procedure.  Outside the procedure, 
+.I spawn_id
+no longer exists, so the spawned process is no longer accessible
+simply because of scoping.  Add a "global spawn_id" to such a procedure.
+
+If you cannot enable the multispawning capability
+(i.e., your system supports neither select (BSD *.*), poll (SVR>2),
+nor something equivalent),
+.B Expect
+will only be able to control a single process at a time.
+In this case, do not attempt to set
+.IR spawn_id ,
+nor should you execute processes via exec while a spawned process
+is running.  Furthermore, you will not be able to
+.B expect
+from multiple processes (including the user as one) at the same time.
+
+Terminal parameters can have a big effect on scripts.  For example, if
+a script is written to look for echoing, it will misbehave if echoing
+is turned off.  For this reason, Expect forces sane terminal
+parameters by default.  Unfortunately, this can make things unpleasant
+for other programs.  As an example, the emacs shell wants to change
+the "usual" mappings: newlines get mapped to newlines instead of
+carriage-return newlines, and echoing is disabled.  This allows one to
+use emacs to edit the input line.  Unfortunately, Expect cannot
+possibly guess this.
+
+You can request that Expect not override its default setting of
+terminal parameters, but you must then be very careful when writing
+scripts for such environments.  In the case of emacs, avoid depending
+upon things like echoing and end-of-line mappings.
+
+The commands that accepted arguments braced into a single list (the
+.B expect
+variants and
+.BR interact )
+use a heuristic to decide if the list is actually one argument or
+many.  The heuristic can fail only in the case when the list actually
+does represent a single argument which has multiple embedded \\n's
+with non-whitespace characters between them.  This seems sufficiently
+improbable, however the argument "\-nobrace" can be used to force a
+single argument to be handled as a single argument.  This could
+conceivably be used with machine-generated Expect code.  Similarly,
+-brace forces a single argument to be handle as multiple patterns/actions.
+
+.SH BUGS
+It was really tempting to name the program "sex" (for either "Smart EXec"
+or "Send-EXpect"), but good sense (or perhaps just Puritanism) prevailed.
+
+On some systems, when a shell is spawned, it complains about not being
+able to access the tty but runs anyway.  This means your system has a
+mechanism for gaining the controlling tty that
+.B Expect
+doesn't know about.  Please find out what it is, and send this information
+back to me.
+
+Ultrix 4.1 (at least the latest versions around here) considers
+timeouts of above 1000000 to be equivalent to 0.
+
+Digital UNIX 4.0A (and probably other versions) refuses to allocate
+ptys if you define a SIGCHLD handler.  See grantpt page for more info.
+
+IRIX 6.0 does not handle pty permissions correctly so that if Expect
+attempts to allocate a pty previously used by someone else, it fails.
+Upgrade to IRIX 6.1.
+
+Telnet (verified only under SunOS 4.1.2) hangs if TERM is not set.
+This is a problem under cron, at and in cgi scripts, which do not
+define TERM.  Thus, you must set it explicitly - to what type is
+usually irrelevant.  It just has to be set to something!  The
+following probably suffices for most cases.
+.nf
+
+    set env(TERM) vt100
+
+.fi
+
+Tip (verified only under BSDI BSD/OS 3.1 i386) hangs if SHELL and HOME
+are not set.  This is a problem under cron, at and in cgi scripts,
+which do not define these environment variables.  Thus, you must set
+them explicitly - to what type is usually irrelevant.  It just has to
+be set to something!  The following probably suffices for most cases.
+.nf
+
+    set env(SHELL) /bin/sh
+    set env(HOME) /usr/local/bin
+
+.fi
+
+
+Some implementations of ptys are designed so that the kernel throws
+away any unread output after 10 to 15 seconds (actual number is
+implementation-dependent) after the process has closed the file
+descriptor.  Thus
+.B Expect
+programs such as
+.nf
+
+    spawn date
+    sleep 20
+    expect
+
+.fi
+will fail.  To avoid this, invoke non-interactive programs with
+.B exec
+rather than
+.BR spawn .
+While such situations are conceivable, in practice I have never
+encountered a situation in which the final output of a truly
+interactive program would be lost due to this behavior.
+
+On the other hand, Cray UNICOS ptys throw away any unread output
+immediately after the process has closed the file descriptor.  I have
+reported this to Cray and they are working on a fix.
+
+Sometimes a delay is required between a prompt and a response, such as
+when a tty interface is changing UART settings or matching baud rates
+by looking for start/stop bits.  Usually, all this is require is to
+sleep for a second or two.  A more robust technique is to retry until
+the hardware is ready to receive input.  The following example uses
+both strategies:
+.nf
+
+    send "speed 9600\\r";
+    sleep 1
+    expect {
+        timeout {send "\\r"; exp_continue}
+        $prompt
+    }
+
+.fi
+
+trap \-code will not work with any command that sits in Tcl's event
+loop, such as sleep.  The problem is that in the event loop, Tcl
+discards the return codes from async event handlers.  A workaround is
+to set a flag in the trap code.  Then check the flag immediately after
+the command (i.e., sleep).
+
+The expect_background command ignores -timeout arguments and has no
+concept of timeouts in general.
+
+.SH "EXPECT HINTS"
+There are a couple of things about
+.B Expect
+that may be non-intuitive.
+This section attempts to address some of these things with a couple of
+suggestions.
+
+A common expect problem is how to recognize shell prompts.  Since
+these are customized differently by differently people and different
+shells, portably automating rlogin can be difficult without knowing
+the prompt.  A reasonable convention is to have users store a regular
+expression describing their prompt (in particular, the end of it) in
+the environment variable EXPECT_PROMPT.  Code like the following
+can be used.  If EXPECT_PROMPT doesn't exist, the code still has a good chance of functioning correctly.
+.nf
+
+    set prompt "(%|#|\\\\$) $"          ;# default prompt
+    catch {set prompt $env(EXPECT_PROMPT)}
+
+    expect -re $prompt
+
+.fi
+I encourage you to write
+.B expect
+patterns that include the end of whatever
+you expect to see.  This avoids the possibility of answering a question
+before seeing the entire thing.  In addition, while you may well be
+able to answer questions before seeing them entirely, if you answer
+early,  your answer may appear echoed back in the middle of the question.
+In other words, the resulting dialogue will be correct but look scrambled.
+
+Most prompts include a space character at the end.
+For example, the prompt from ftp is 'f', 't', 'p', '>' and <blank>.
+To match this prompt, you must account for each of these characters.
+It is a common mistake not to include the blank.
+Put the blank in explicitly.
+
+If you use a pattern of the form X*, the * will match all the output
+received from the end of X to the last thing received.
+This sounds intuitive but can be somewhat confusing because the phrase
+"last thing received" can vary depending upon the speed of the computer
+and the processing of I/O both by the kernel and the device driver.
+.PP
+In particular, humans tend to see program output arriving in huge chunks
+(atomically) when in reality most programs produce output one
+line at a time.  Assuming this is the case, the * in the pattern of the
+previous paragraph may only match the end of the current line even though
+there seems to be more, because at the time of the match that was all
+the output that had been received.
+.PP
+.B expect
+has no way of knowing that further output is coming unless your
+pattern specifically accounts for it.
+.PP
+Even depending on line-oriented buffering is unwise.  Not only do programs
+rarely make promises about the type of buffering they do, but system
+indigestion can break output lines up so that lines break at seemingly
+random places.  Thus, if you can express the last few characters
+of a prompt when writing patterns, it is wise to do so.
+
+If you are waiting for a pattern in the last output of a program
+and the program emits something else instead, you will not be able to
+detect that with the
+.B timeout
+keyword.  The reason is that
+.B expect
+will not timeout \- instead it will get an
+.B eof
+indication.
+Use that instead.  Even better, use both.  That way if that line
+is ever moved around, you won't have to edit the line itself.
+
+Newlines are usually converted to carriage return, linefeed sequences
+when output by the terminal driver.  Thus, if you want a pattern that
+explicitly matches the two lines, from, say, printf("foo\\nbar"),
+you should use the pattern "foo\\r\\nbar".
+.PP
+A similar translation occurs when reading from the user, via
+.BR expect_user .
+In this case, when you press return, it will be
+translated to a newline.  If
+.B Expect
+then passes that to a program
+which sets its terminal to raw mode (like telnet), there is going to
+be a problem, as the program expects a true return.  (Some programs
+are actually forgiving in that they will automatically translate
+newlines to returns, but most don't.)  Unfortunately, there is no way to find
+out that a program put its terminal into raw mode.
+.PP
+Rather than manually replacing newlines with returns, the solution is to
+use the command "stty raw", which will stop the translation.
+Note, however, that this means that you will no longer get the cooked
+line-editing features.
+.PP
+.B interact
+implicitly sets your terminal to raw mode so this problem will not arise then.
+
+It is often useful to store passwords (or other private information)
+in
+.B Expect
+scripts.  This is not recommended since anything that is
+stored on a computer is susceptible to being accessed by anyone.
+Thus, interactively prompting for passwords from a script is a smarter
+idea than embedding them literally.  Nonetheless, sometimes such embedding
+is the only possibility.
+.PP
+Unfortunately, the UNIX file system has no direct way of creating
+scripts which are executable but unreadable.  Systems which support
+setgid shell scripts may indirectly simulate this as follows:
+.PP
+Create the
+.B Expect
+script (that contains the secret data) as usual.
+Make its permissions be 750 (\-rwxr\-x\-\-\-) and owned by a trusted group,
+i.e., a group which is allowed to read it.  If necessary, create a new
+group for this purpose.  Next, create a /bin/sh script with
+permissions 2751 (\-rwxr\-s\-\-x) owned by the same group as before.
+.PP
+The result is a script which may be executed (and read) by anyone.
+When invoked, it runs the
+.B Expect
+script.

+.TH LIBEXPECT 3 "12 December 1991"
+.SH NAME
+libexpect \- programmed dialogue library with interactive programs
+.SH DESCRIPTION
+This library contains functions that allow Expect to be used as
+a Tcl extension or to be used directly from C or C++ (without Tcl).
+Adding Expect as a Tcl extension is very short and simple, so that will be
+covered first.
+.SH SYNOPSIS
+.nf
+
+.B #include "expect_tcl.h"
+.B Expect_Init(interp);
+
+.B cc files... \-lexpect5.20 \-ltcl7.5 \-lm
+
+.fi
+Note: library versions may differ in the actual release.
+
+The Expect_Init function adds expect commands to the named
+interpreter.  It avoids overwriting commands that already exist,
+however aliases beginning with "exp_" are always created for expect
+commands.  So for example, "send" can be used as "exp_send".
+
+Generally, you should only call Expect commands via Tcl_Eval.
+Certain auxiliary functions may be called directly.  They are summarized
+below.  They may be useful in constructing your own main.  Look
+at the file exp_main_exp.c in the Expect distribution as
+a prototype main.  Another prototype is tclAppInit.c in the
+Tcl source distribution.  A prototype for working with Tk is in
+exp_main_tk.c in the Expect distribution.
+.nf
+
+int exp_cmdlinecmds;
+int exp_interactive;
+FILE *exp_cmdfile;
+char *exp_cmdfilename;
+int exp_tcl_debugger_available;
+
+void	exp_parse_argv(Tcl_Interp *,int argc,char **argv);
+int	exp_interpreter(Tcl_Interp *);
+void	exp_interpret_cmdfile(Tcl_Interp *,FILE *);

+void	exp_exit(Tcl_Interp *,int status);
+void	exp_exit_handlers(Tcl_Interp *);
+void	exp_error(Tcl_Interp,char *,...);
+
+.fi
+.B exp_cmdlinecmds
+is 1 if Expect has been invoked with commands on the program command-line (using "-c" for example).
+.B exp_interactive
+is 1 if Expect has been invoked with the -i flag or if no commands or script is being invoked.
+.B exp_cmdfile
+is a stream from which Expect will read commands.
+.B exp_cmdfilename
+is the name of a file which Expect will open and read commands from.
+.B exp_tcl_debugger_available
+is 1 if the debugger has been armed.
+
+.B exp_parse_argv
+reads the representation of the command line.
+Based on what is found, any of the other variables listed here
+are initialized appropriately.
+.B exp_interpreter
+interactively prompts the user for commands and evaluates them.
+.B exp_interpret_cmdfile
+reads the given stream and evaluates any commands found.
+.B exp_interpret_cmdfilename
+opens the named file and evaluates any commands found.
+.B exp_interpret_rcfiles
+reads and evalutes the .rc files.  If my_rc is zero,
+then ~/.expectrc is skipped.  If sys_rc is zero, then the system-wide
+expectrc file is skipped.
+.B exp_cook
+returns a static buffer containing the argument reproduced with
+newlines replaced by carriage-return linefeed sequences.
+The primary purpose of this is to allow messages to be produced
+without worrying about whether the terminal is in raw mode or
+cooked mode.
+If length is zero, it is computed via strlen.
+.B exp_error is a printf-like function that writes the result
+to interp->result.

+
+.B cc files... \-lexpect \-ltcl \-lm
+.fi
+
+.SH DESCRIPTION
+.B exp_spawnl
+and
+.B exp_spawnv
+fork a new process so that its stdin,
+stdout, and stderr can be written and read by the current process.
+.I file
+is the name of a file to be executed.  The
+.I arg
+pointers are
+null-terminated strings.  Following the style of execve(),
+.I arg0
+(or
+.IR argv0 )
+is customarily a duplicate of the name of the file.
+.PP
+Four interfaces are available,
+.B exp_spawnl
+is useful when the number of
+arguments is known at compile time.
+.B exp_spawnv
+is useful when the number of arguments is not known at compile time.
+.B exp_spawnfd
+is useful when an open file descriptor is already available as a source.
+.B exp_popen
+is explained later on.
+.PP
+If the process is successfully created, a file descriptor is returned
+which corresponds to the process's stdin, stdout and stderr.
+A stream may be associated with the file descriptor by using fdopen().
+(This should almost certainly be followed by setbuf() to unbuffer the I/O.)
+.PP
+Closing the file descriptor will typically be detected by the
+process as an EOF.  Once such a process exits, it should be waited
+upon (via wait) in order to free up the kernel process slot.  (Some systems
+allow you to avoid this if you ignore the SIGCHLD signal).
+.PP
+.B exp_popen
+is yet another interface, styled after popen().  It takes a Bourne
+shell command line, and returns a stream that corresponds to the process's
+stdin, stdout and stderr.  The actual implementation of
+.B exp_popen
+below demonstrates
+.BR exp_spawnl .
+.nf
+
+FILE *
+exp_popen(program)
+char *program;
+{
+	FILE *fp;
+	int ec;
+
+	if (0 > (ec = exp_spawnl("sh","sh","-c",program,(char *)0)))
+		return(0);
+	if (NULL == (fp = fdopen(ec,"r+")) return(0);
+	setbuf(fp,(char *)0);
+	return(fp);
+}
+.fi
+
+After a process is started, the variable
+.B exp_pid
+is set to the process-id of the new process.  The variable
+.B exp_pty_slave_name
+is set to the name of the slave side of the pty.
+
+The spawn functions uses a pty to communicate with the process.  By
+default, the pty is initialized the same way as the user's tty (if
+possible, i.e., if the environment has a controlling terminal.)  This
+initialization can be skipped by setting exp_ttycopy to 0.
+
+The pty is further initialized to some system wide defaults if
+exp_ttyinit is non-zero.  The default is generally comparable to "stty sane".
+
+The tty setting can be further modified by setting the variable
+.BR exp_stty_init .
+This variable is interpreted in the style of stty arguments.  For
+example, exp_stty_init = "sane"; repeats the default initialization.
+
+On some systems, it is possible to redirect console output to ptys.
+If this is supported, you can force the next spawn to obtain the
+console output by setting the variable
+.B exp_console
+to 1.
+
+Between the time a process is started and the new program is given
+control, the spawn functions can clean up the environment by closing
+file descriptors.  By default, the only file descriptors closed are
+ones internal to Expect and any marked "close-on-exec".
+
+If needed, you can close additional file descriptors by creating
+an appropriate function and assigning it to exp_close_in_child.
+The function will be called after the fork and before the exec.
+(This also modifies the behavior of the spawn command in Expect.)
+
+If you are also using Tcl, it may be convenient to use the function
+exp_close_tcl_files which closes all files between the default
+standard file descriptors and the highest descriptor known to Tcl.
+(Expect does this.)
+
+The function exp_child_exec_prelude is the last function called prior
+to the actual exec in the child.  You can redefine this for effects
+such as manipulating the uid or the signals.
+
+.SH "IF YOU WANT TO ALLOCATE YOUR OWN PTY"
+.nf
+
+.B extern int exp_autoallocpty;
+.B extern int exp_pty2;
+.fi
+
+The spawn functions use a pty to communicate with the process.  By
+default, a pty is automatically allocated each time a process is spawned.
+If you want to allocate ptys yourself, before calling one of the spawn
+functions, set
+.B exp_autoallocpty
+to 0,
+.B exp_pty0
+to the master pty file descriptor and
+.B exp_pty1
+to the slave pty file descriptor.
+The expect library will not do any pty initializations (e.g., exp_stty_init will not be used).
+The slave pty file descriptor will be
+automatically closed when the process is spawned.  After the process is
+started, all further communication takes place with the master pty file
+descriptor.
+.PP
+.B exp_spawnl
+and
+.B exp_spawnv
+duplicate the shell's actions
+in searching for an executable file in a list of directories.  The
+directory list is obtained from the environment.
+.SH EXPECT PROCESSING
+While it is possible to use read() to read information from a process
+spawned by
+.B exp_spawnl
+or
+.BR exp_spawnv ,
+more convenient functions are provided.  They are as
+follows:
+.nf
+
+.B int
+.B exp_expectl(fd,type1,pattern1,re1,,value1,type2,...,exp_end);
+.B int fd;
+.B enum exp_type type;
+.B char *pattern1, *pattern2, ...;
+.B regexp *re1, *re2, ...;
+.B int value1, value2, ...;
+.B
+
+.B int
+.B exp_fexpectl(fp,type1,pattern1,re1,value1,type2,...,exp_end);
+.B FILE *fp;
+.B enum exp_type type;
+.B char *pattern1, *pattern2, ...;
+.B regexp *re1, *re2, ...;
+.B int value1, value2, ...;
+
+.B enum exp_type {
+.B	exp_end,
+.B	exp_glob,
+.B	exp_exact,
+.B	exp_regexp,
+.B	exp_compiled,
+.B	exp_null,
+.B };
+
+.B struct exp_case {
+.B	char *pattern;
+.B	regexp *re;
+.B	enum exp_type type;
+.B	int value;
+.B };
+
+.B int
+.B exp_expectv(fd,cases);
+.B int fd;
+.B struct exp_case *cases;
+
+.B int
+.B exp_fexpectv(fp,cases);
+.B FILE *fp;
+.B struct exp_case *cases;
+
+.B extern int exp_timeout;
+.B extern char *exp_match;
+.B extern char *exp_match_end;
+.B extern char *exp_buffer;
+.B extern char *exp_buffer_end;
+.B extern int exp_match_max;
+.B extern int exp_full_buffer;
+.B extern int exp_remove_nulls;
+.fi
+
+The functions wait until the output from a process matches one of the
+patterns, a specified time period has passed, or an EOF is seen.
+.PP
+The first argument to each function is either a file descriptor or a stream.
+Successive sets of arguments describe patterns and associated integer values
+to return when the pattern matches.
+.PP
+The type argument is one of four values.  exp_end indicates that no more
+patterns appear.
+exp_glob indicates that the pattern is a glob-style string pattern.
+exp_exact indicates that the pattern is an exact string.
+exp_regexp indicates that the pattern is a regexp-style string pattern.
+exp_compiled indicates that the pattern is a regexp-style string pattern,
+and that its compiled form is also provided.
+exp_null indicates that the pattern is a null (for debugging purposes,
+a string pattern must also follow).
+.PP
+If the compiled form is not provided with the functions
+.B exp_expectl
+and
+.BR exp_fexpectl ,
+any pattern compilation done internally is
+thrown away after the function returns.  The functions
+.B exp_expectv
+and
+.B exp_fexpectv
+will automatically compile patterns and will not throw them away.
+Instead, they must be discarded by the user, by calling free on each
+pattern.  It is only necessary to discard them, the last time the
+cases are used.
+.PP
+Regexp subpatterns matched are stored in the compiled regexp.
+Assuming "re" contains a compiled regexp, the matched string can be
+found in re->startp0.  The match substrings (according to the parentheses)
+in the original pattern can be found in re->startp1, re->startp2, and
+so on, up to re->startp9.  The corresponding strings ends are re->endpx
+where x is that same index as for the string start.
+
+The type exp_null matches if a null appears in the input.  The
+variable exp_remove_nulls must be set to 0 to prevent nulls from
+being automatically stripped.  By default, exp_remove_nulls is set
+to 1 and nulls are automatically stripped.
+
+.B exp_expectv
+and
+.B exp_fexpectv
+are useful when the number of patterns is
+not known in advance.  In this case, the sets are provided in an array.
+The end of the array is denoted by a struct exp_case with type exp_end.
+For the rest
+of this discussion, these functions will be referred to generically as
+.IR expect.
+.PP
+If a pattern matches, then the corresponding integer value is returned.
+Values need not be unique, however they should be positive to avoid
+being mistaken for EXP_EOF, EXP_TIMEOUT, or EXP_FULLBUFFER.
+Upon EOF or timeout, the value
+.B EXP_EOF
+or
+.B EXP_TIMEOUT
+is returned.  The
+default timeout period is 10 seconds but may be changed by setting the
+variable
+.BR exp_timeout .
+A value of -1
+disables a timeout from occurring.
+A value of 0 causes the expect function to return immediately (i.e., poll)
+after one read().
+However it must be preceded by a function such as select, poll, or 
+an event manager callback to guarantee that there is data to be read.
+
+If the variable exp_full_buffer is 1, then EXP_FULLBUFFER is returned
+if exp_buffer fills with no pattern having matched.
+
+When the expect function returns,
+.B exp_buffer
+points to the buffer
+of characters that was being considered for matching.
+.B exp_buffer_end
+points to one past the last character in exp_buffer.
+If a match occurred,
+.B exp_match
+points into
+.B exp_buffer
+where the match began.
+.B exp_match_end
+points to one character past where the match ended.
+.PP
+Each time new input arrives, it is compared to each pattern in the
+order they are listed.  Thus, you may test for absence of a match by
+making the last pattern something guaranteed to appear, such as a
+prompt.  In situations where there is no prompt, you must check for
+.B EXP_TIMEOUT
+(just like you would if you were interacting manually).  More philosophy
+and strategies on specifying
+.B expect
+patterns can be found in the
+documentation on the
+.B expect
+program itself.  See SEE ALSO below.
+.PP
+Patterns are the usual C-shell-style regular expressions.  For
+example, the following fragment looks for a successful login, such
+as from a telnet dialogue.
+.nf
+
+	switch (exp_expectl(
+		exp_glob,"connected",CONN,
+		exp_glob,"busy",BUSY,
+		exp_glob,"failed",ABORT,
+		exp_glob,"invalid password",ABORT,
+		exp_end)) {
+	case CONN:	/* logged in successfully */
+		break;
+	case BUSY:	/* couldn't log in at the moment */
+		break;
+	case EXP_TIMEOUT:
+	case ABORT:	/* can't log in at any moment! */
+		break;
+	default: /* problem with expect */
+	}
+.fi
+
+Asterisks (as in the
+example above) are a useful shorthand for omitting line-termination
+characters and other detail.
+Patterns must match the entire output of the current process (since
+the previous read on the descriptor or stream).  
+More than 2000 bytes of output can
+force earlier bytes to be "forgotten".  This may be changed by setting
+the variable
+.BR exp_match_max .
+Note that excessively large values can slow down the pattern matcher.
+.SH RUNNING IN THE BACKGROUND
+.nf
+
+.B extern int exp_disconnected;
+.B int exp_disconnect();
+
+.fi
+It is possible to move a process into the background after it has
+begun running.  A typical use for this is to read passwords and then
+go into the background to sleep before using the passwords to do real
+work.
+.PP
+To move a process into the background, fork, call exp_disconnect() in the
+child process and exit() in the parent process.  This disassociates
+your process from the controlling terminal.  If you wish to move a
+process into the background in a different way, you must set the
+variable exp_disconnected to 1.  This allows processes spawned after
+this point to be started correctly.
+.SH MULTIPLEXING
+By default, the expect functions block inside of a read on a single file
+descriptor.  If you want to wait on patterns from multiple file
+descriptors,
+use select, poll, or an event manager.
+They will tell you what file descriptor is ready to read.
+
+When a file descriptor is ready to read, you can use the expect
+functions to do one and only read by setting timeout to 0.  
+.SH SLAVE CONTROL
+
+.nf
+
+.B void
+.B exp_slave_control(fd,enable)
+.B int fd;
+.B int enable;
+
+.fi
+
+Pty trapping is normally done automatically by the expect functions.
+However, if you want to issue an ioctl, for example, directly on the
+slave device, you should temporary disable trapping.
+
+Pty trapping can be controlled with exp_slave_control.  The first
+argument is the file descriptor corresponding to the spawned process.
+The second argument is a 0 if trapping is to be disabled and 1 if it
+is to be enabled.  
+
+.SH ERRORS
+All functions indicate errors by returning \-1 and setting errno.
+.PP
+Errors that occur after the spawn functions fork (e.g., attempting to
+spawn a non-existent program) are written to the process's stderr,
+and will be read by the first
+.BR expect .
+.SH SIGNALS

+.B expect

+it will timeout prematurely.
+.PP
+Internally,
+.B expect
+calls read() which can be interrupted by signals.  If
+you define signal handlers, you can choose to restart or abort
+.BR expect 's
+internal read.  The variable,
+.BR exp_reading ,
+is true if (and only if)
+.BR expect 's

+.B extern int exp_loguser;
+.B extern int exp_logfile_all
+.B extern FILE *exp_logfile;
+.fi
+
+If
+.B exp_loguser
+is nonzero,
+.B expect
+sends any output from the spawned process to
+stdout.  Since interactive programs typically echo their input, this
+usually suffices to show both sides of the conversation.  If
+.B exp_logfile
+is also nonzero, this same output is written to the stream defined by 
+.BR exp_logfile .
+If 
+.B exp_logfile_all
+is non-zero,
+.B exp_logfile
+is written regardless of the value of 
+.BR exp_loguser .
+
+.SH DEBUGGING
+While I consider the library to be easy to use, I think that the
+standalone expect program is much, much, easier to use than working
+with the C compiler and its usual edit, compile, debug cycle.  Unlike
+typical C programs, most of the debugging isn't getting the C compiler
+to accept your programs - rather, it is getting the dialogue correct.
+Also, translating scripts from expect to C is usually not necessary.
+For example, the speed of interactive dialogues is virtually never an
+issue.  So please try the standalone 'expect' program first.  I
+suspect it is a more appropriate solution for most people than the
+library.
+.PP
+Nonetheless, if you feel compelled to debug in C,
+here are some tools to help you.
+.nf
+
+.B extern int exp_is_debugging;
+.B extern FILE *exp_debugfile;
+.fi
+
+While expect dialogues seem very intuitive, trying to codify them in a
+program can reveal many surprises in a program's interface.  Therefore
+a variety of debugging aids are available.  They are controlled by the
+above variables, all 0 by default.
+
+Debugging information internal to
+.B expect
+is sent to stderr when
+.B exp_is_debugging
+is non-zero.  The debugging information includes
+every character received, and every attempt made to match the current
+input against the patterns.  In addition, non-printable characters are
+translated to a printable form.  For example, a control-C appears as a
+caret followed by a C.  If 
+.B exp_logfile
+is non-zero, this information
+is also written to that stream.
+.PP
+If 
+.B exp_debugfile
+is non-zero, all normal and debugging information is
+written to that stream, regardless of the value of 
+.BR exp_is_debugging .
+.SH CAVEATS
+The stream versions of the
+.B expect
+functions are much slower than the
+file descriptor versions because there is no way to portably read
+an unknown number of bytes without the potential of timing out.
+Thus, characters are read one at a time.  You are therefore strongly
+encouraged to use the file descriptor versions of
+.B expect
+(although,
+automated versions of interactive programs don't usually demand high speed
+anyway).
+.PP
+You can actually get the best of both worlds, writing with the usual
+stream functions and reading with the file descriptor versions of
+.B expect
+as long as you don't attempt to intermix other stream input
+functions (e.g., fgetc).
+To do this, pass fileno(stream) as the file descriptor each time.
+Fortunately, there is little reason to use anything but the
+.B expect
+functions when reading from interactive programs.
+.PP
+There is no matching exp_pclose to exp_popen (unlike popen and pclose).
+It only takes two functions to close down a connection (fclose() followed
+by waiting on the pid), but it is not uncommon to separate these two
+actions by large time intervals, so the function seems of little value.
+.PP
+If you are running on a Cray running Unicos (all I know for sure from
+experience), you must run your compiled program as root or setuid.  The
+problem is that the Cray only allows root processes to open ptys. 
+You should observe as much precautions as possible:  If you don't need
+permissions, setuid(0) only immediately before calling one of the spawn
+functions and immediately set it back afterwards.
+.PP
+Normally,
+.B spawn
+takes little time to execute.  If you notice spawn taking a
+significant amount of time, it is probably encountering ptys that are
+wedged.  A number of tests are run on ptys to avoid entanglements with
+errant processes.  (These take 10 seconds per wedged pty.)  Running
+expect with the \-d option will show if
+.B expect
+is encountering many ptys in odd states.  If you cannot kill
+the processes to which these ptys are attached, your only recourse may
+be to reboot.
+.SH BUGS
+The
+.B exp_fexpect
+functions don't work at all under HP-UX - it appears to be a bug in getc.
+Follow the
+advice (above) about using the
+.B exp_expect
+functions (which doesn't need to call getc).  If you fix the problem (before
+I do - please check the latest release) let me know.
+.SH SEE ALSO
+An alternative to this library is the
+.B expect
+program.
+.B expect
+interprets scripts written in a high-level language
+which direct the dialogue.
+In addition, the user can take control and interact directly when desired.
+If it is not absolutely necessary to write your own C program, it is much
+easier to use
+.B expect
+to perform the entire interaction.

+#                       to use shared libraries on this platform.
+#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
+#                       in a static or shared library name, using the $VERSION variable
+#                       to put the version in the right place.  This is used
+#                       by platforms that need non-standard library names.
+#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
+#                       to have a version after the .so, and ${VERSION}.a
+#                       on AIX, since a shared library needs to have

+#                       extensions have a .so extension.  Defaults to

+Expect Test Suite
+-----------------
+
+This directory contains a set of validation tests for the Expect
+commands.  Each of the files whose name ends in ".test" is intended to
+fully exercise one or a few Expect commands.  The commands tested by a
+given file are listed in the first line of the file.
+
+You can run the tests in three ways:
+
+    (a) type "make test" in the parent directory to this one; this
+        will run all of the tests.
+
+    (b) type "expect <testFile> ?<option> <value>?
+	Command line options include:
+
+	-help                display usage information
+
+	-verbose <level>     set the level of verbosity to a substring
+			     of "bps".  See the "Test output" section
+			     of the tcltest man page for an
+			     explanation of this option. 
+
+	-match <matchList>   only run tests that match one or more of
+			     the glob patterns in <matchList>
+
+	-skip <skipList>     do not run tests that match one or more
+			     of the glob patterns in <skipList>
+
+	-file <globPatternList>  
+		             only source test files that match one or
+		             more of the glob patterns in
+		             <globPatternList> (relative to the
+		             "tests" directory).  This option only
+		             applies when you run the test suite with
+		             the "all.tcl" file.
+
+	-notfile <globPatternList>  
+	                     do not source test files that match one
+	                     or more of the patterns in
+	                     <globPatternList> (relative to the
+	                     "tests" directory).  This option only
+	                     applies when you run the test suite with
+	                     the "all.tcl" file.
+
+	-constraints <list>  tests with any constraints in <list> will
+			     not be skipped.  Not that elements of
+			     <list> must exactly match the existing
+			     constraints.
+
+        -limitconstraints <bool>
+                             If 1, limit test runs to those tests that
+                             match the constraints listed using the
+                             -constraints flag.  Use of this flag
+                             requires use of the -constraints flag.
+                             The default value is 0.
+
+        -tmpdir <dirname>    put temporary files created by
+                             ::tcltest::makeFile and
+                             ::tcltest::makeDirectory in the named
+                             directory.  The default location is
+                             ::tcltest::workingDirectory.
+
+        -preservecore <level>
+                             check for core files.  If level is 0,
+                             check for core files only when
+                             cleanupTests is called from an all.tcl
+                             file.  If 1, also check at the end of
+                             every test command.  If 2, also save core
+                             files in ::tcltest::temporaryDirectory.
+                             The default level is 0.
+ 
+    (c) start up expect in this directory, then "source" the test
+        file (for example, type "source parse.test").  To run all
+	of the tests, type "source all.tcl".  To use the options in
+	interactive mode, you can set their corresponding tcltest
+	namespace variables after loading the tcltest package.
+	For example, some of the tcltest variables are:
+		  ::tcltest::match
+		  ::tcltest::skip
+		  ::tcltest::testConstraints(nonPortable)
+		  ::tcltest::testConstraints(knownBug)
+		  ::tcltest::testConstraints(userInteractive)
+
+Please see the man page for the 'tcltest' package for more detailed
+information on the features of the testing environment.
+
+This approach to testing was copied from the Tcl distribution.
+
+Incompatibilities with prior versions
+-------------------------------------
+
+1) Global variables such as VERBOSE, TESTS, and testConfig are now
+   renamed to use the new "tcltest" namespace.
+
+   old name   new name
+   --------   --------
+   VERBOSE    ::tcltest::verbose
+   TESTS      ::tcltest::match
+   testConfig ::tcltest::testConstraints
+
+2) VERBOSE values are no longer numeric.  
+
+3) When you run "make test", the working dir for the test suite is now
+   the one from which you called "make test", rather than the "tests"
+   directory.  This change allows for both unix and windows test
+   suites to be run simultaneously without interference with each
+   other or with existing files.  All tests must now run independently
+   of their working directory.
+
+4) The "all" file is now called all.tcl.
+
+5) The "defs" file no longer exists.
+
+6) Instead of creating a doAllTests file in the tests directory, to
+   run all nonPortable tests, just use the "-constraints nonPortable"
+   command line flag.  If you are running interactively, you can set
+   the ::tcltest::testConstraints(nonPortable) variable to 1 (after
+   loading the tcltest package).

+\`configure' configures exp_test 0.43 to adapt to many kinds of systems.
+
+Usage: $0 OPTION... VAR=VALUE...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE disabled
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR configure dir or \`..'
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          $ac_default_prefix
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          PREFIX
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables EPREFIX/bin
+  --sbindir=DIR           system admin executables EPREFIX/sbin
+  --libexecdir=DIR        program executables EPREFIX/libexec
+  --sysconfdir=DIR        read-only single-machine data PREFIX/etc
+  --sharedstatedir=DIR    modifiable architecture-independent data PREFIX/com
+  --localstatedir=DIR     modifiable single-machine data PREFIX/var
+  --runstatedir=DIR       modifiable per-process data LOCALSTATEDIR/run
+  --libdir=DIR            object code libraries EPREFIX/lib
+  --includedir=DIR        C header files PREFIX/include
+  --oldincludedir=DIR     C header files for non-gcc /usr/include
+  --datarootdir=DIR       read-only arch.-independent data root PREFIX/share
+  --datadir=DIR           read-only architecture-independent data DATAROOTDIR
+  --infodir=DIR           info documentation DATAROOTDIR/info

+  --with-tcl              directory containing tcl configuration
+                          (tclConfig.sh)
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.
