# Script to start a JMRI class directly, e.g during development
#
# First argument is a fully-qualified class name. Any standard JMRI POSIX
# launcher options may precede the first argument. Run this script with the
# --help option for details.
#
# If the class has a main() method, that's launched.  This works
# for running e.g. early-JUnit test classes, and applications
# like apps.DecoderPro.DecoderPro
#
# If there is no main() method found in the named class, an
# org.junit.runner.JUnitCore runner is asked to try to run the
# class as JUnit4 tests.
#
# This works by calling .run.sh, which is generated from the JMRI POSIX launcher
# by running 'ant run-sh'
#
# By default this script sets the JMRI settings: dir to the directory "temp" in
# the directory its run from. Pass the option --settingsdir="" to use the JMRI
# default location. test/jmri.conf in the directory this script is run from is
# used to pull any persistent settings unless --settingsdir=... is specified.
#
# Note that this script may mangle arguments with unescaped spaces. This can be
# avoided by writing spaces in arguments as "arg\ with\ spaces" or by wrapping
# arguments with spaces in extra, escaped quotes like "\"arg with spaces\"".
#
# If you need to add any additional Java options or defines,
# include them in the JMRI_OPTIONS environment variable
#
#  jmri.demo                Keep some test windows open after tests run
#  java.awt.headless        Tests won't attempt to use screen
#  jmri.skipschematests     Skip tests of XML schema if true
#  jmri.skipscripttests     Skip tests of Jython scripts if true
#  jmri.log4jconfigfilename Specify replacement for details tests_lcf.xml file (tests only)
#
# E.g.:
# setenv JMRI_OPTIONS -Djmri.skipschematests=true
#
# You can run separate instances of the program with their
# own preferences and setup if you provide the name of a configuration file
# as the 1st argument
#
# If you are getting X11 warnings about meta keys, uncomment the next line
# xprop -root -remove _MOTIF_DEFAULT_BINDINGS
