|
# NOTE: The recommended way to add a script button to JMRI is to
|
|
# use the Startup Items preferences to add that button when the function is available.
|
|
#
|
|
# NOTE: This script does not support DecoderPro. Use the recommended
|
|
# method if you need to add a script to a button in DecoderPro.
