###| Builder Script |###
#
# Builds all permutations of modules
# This script is an attempt to maintain module sanity as new ones are added
#
# Fortunately, sweeping API changes don't happen much anymore...but just in case...

## TODO List ##
# - Complete non-Scan module permutations (will take extra work)
# - Add command line arguments
# - Add help flag for usage
# - Make sure the script is being run from the correct directory
