+# **what?**
+# Cleanup branches left over from automation and testing.  Also cleanup
+# draft releases from release testing.
+
+# **why?**
+# The automations are leaving behind branches and releases that clutter
+# the repository.  Sometimes we need them to debug processes so we don't
+# want them immediately deleted.  Running on Saturday to avoid running
+# at the same time as an actual release to prevent breaking a release
+# mid-release.
+
+# **when?**
+# Mainly on a schedule of 12:00 Saturday.
+# Manual trigger can also run on demand
