# Interlisp workflow to build Medley release and push it to github. This workflow
# is platform independent - but runs on Linux/amd64.
#
# This workflow contains a sentry that causes it to skip the build (as identified
# by its commit SHA) if its already been done.  Setting the "force" input to true
# will bypass this sentry,
