# this is a sample script that can be called from reinstallMods
#
# CommonResources provides:
#   code to determine if it was called from reinstallMods or manually from a command line
#   code to insert the script into scriptsList
#   code to control exitting the program or processing by reinstallMods
#    or prompting the user
#
#   functions to make it easier to install and remove modified files from Venus
#
#   The SetupHelper package includes CommonResources
#   and a script to reinstall programs after a Venus software update
#   SetupHelper should be installed before running this script
