JIMRI/scripts/AppScriptTemplate

#! /bin/bash
#
# Script to start a JMRI @VERSION@ application.
#
# This script is used for both all POSIX operating systems including Linux
# and macOS / OS X application bundles.
#
# If a "jre" directory is found in the current working directory,
# it's assumed that contains a correct JRE or JDK which will be used
# regardless of the setting of ${JAVA_HOME}
#
# If you need to specify an option with spaces in it, escape the spaces with a
# leading backslash like "\ ".
#
# If you need to add any persistent Java options or persistent command line
# arguments, include them in the "default_options" statement in the file
# jmri.conf in the settings directory.
#
# The default location for the settings directory is:
# - macOS / OS X: ${HOME}/Library/Preferences/JMRI
# - all other: ${HOME}/.jmri
#
# The settings directory can be set to a non-standard location using the
# "--settingsdir=/path/to/my/settings" command line option (unlike all other
# options, this one cannot be set in the jmri.conf file, since it determines
# from where the jmri.conf file is read).
#
# If your serial ports are not in the default list, include the names in the
# command line argument --serial-ports separated by commas:
#    --serial-ports=locobuffer,cmri
#
# You can run separate instances of the program with their own preferences
# if you
# - Provide the name of a configuration file as a parameter
# or
# - Copy and rename this script.
#
# If you rename the script to, for example, JmriNew, it will use
# "JmriNewConfig.properties" as it's configuration file. Note that configuration
# files only determine which profile to use, and if the profile selector should
# be shown at application launch.
#
# If you are getting X11 warnings about meta keys, uncomment the next line
# xprop -root -remove _MOTIF_DEFAULT_BINDINGS
#
# For more information, please see
# http://jmri.org/help/en/html/doc/Technical/StartUpScripts.shtml

# prevent the use of unbound variables
