# Name: epics-jenkins.py
# Abs: A tool to handle jenkins SCM polling jobs.
#
# This script can be run by jenkins for any commits to the repo
# and must determine which, if any, branches need to a build test
# and which new releases, if any, need to be built.
# Needs to support builds for multiple EPICS base releases.
#
# Arguments:
# ?
# Example:
# epics-jenkins -p iocAdmin/R3.1.15-1.0.0
#
# Supports smart defaults and overrides for:
# * EPICS_MODULES - path to top of EPICS modules directory
# * EPICS_TOP or EPICS_SITE_TOP - path to top of EPICS release area
#
# Auth: 01-Dec-2020, Bruce Hill (bhill)
# Rev: dd-mmm-yyyy, Reviewer's Name (USERNAME)
#
# Requested features to be added:
