File _service:tar_scm:jetty.sh of Package jetty

#!/usr/bin/env bash
# Configuration files
#
# /etc/default/jetty
#   If it exists, this is read at the start of script. It may perform any
#   sequence of shell commands, like setting relevant environment variables.
#
# /etc/jetty.conf
#   If found, and no configurations were given on the command line,
#   the file will be used as this script's configuration.
#   Each line in the file may contain:
#     - A comment denoted by the pound (#) sign as first non-blank character.
#     - The path to a regular file, which will be passed to jetty as a
#       config.xml file.
#     - The path to a directory. Each *.xml file in the directory will be
#       passed to jetty as a config.xml file.
#     - All other lines will be passed, as-is to the start.jar
#
#   The files will be checked for existence before being passed to jetty.
#
# Configuration variables
#
# JAVA
#   Command to invoke Java. If not set, java (from the PATH) will be used.
#
# JAVA_OPTIONS
#   Extra options to pass to the JVM
#
# JETTY_HOME
#   Where Jetty is installed. If not set, the script will try go
#   guess it by first looking at the invocation path for the script,
#   and then by looking in standard locations as $HOME/opt/jetty
#   and /opt/jetty. The java system property "jetty.home" will be
#   set to this value for use by configure.xml files, f.e.:
#
#    <Arg><Property name="jetty.home" default="."/>/webapps/jetty.war</Arg>
#
# JETTY_BASE
#   Where your Jetty base directory is.  If not set, the value from
#   $JETTY_HOME will be used.
#
# JETTY_ARGS
#   The default arguments to pass to jetty.
#   For example
#      JETTY_ARGS=jetty.port=8080 jetty.spdy.port=8443 jetty.secure.port=443
#
