# Production release script for creating a new release of JACS2
#
# To create a release branch:
#   1) Request a code freeze from developers on the master branch
#   2) Make sure you have master checked out, and you are synchronized with origin
#   3) Run this script, passing in the release version number as a parameter
#   4) Lift the code freeze
#
# You can now do a production build using the release branch jacs_<VERSION>
#

# Exit after any error
