# Publish CVS commits to a RSS feed.
#
# This is a Python port of Dave Thomas's commit2rss.rb, because SourceForge
# doesn't support Ruby cvs scripts yet.
#
# To use: checkout your repository's CVSROOT module, edit loginfo, and
# add a line similar to this:
#
# ALL /path/to/commit2rss.py %{}
#
# More CVS trigger info at:
# https://www.cvshome.org/docs/manual/cvs-1.11.17/cvs_18.html#SEC167
