# Optional Flag: -t to cause the script to actually tag the github repo
# Using -t will cause the original behavior of Jerry's version.
# Not using -t will not touch the github repo or tags. Just will set the VERSION output and VERSION file

# Optional Argument: path to VERSION file. Defaults to VERSION in the current director
# major and minor, once released, are designated by add RELEASE-vx.y tag and the patch will be derived based on distance to that tag
