+# This script contains porcelain and porcelain byproducts.
+# It's Python because the Python standard libraries avoid portability/security
+# issues raised by callouts in the ancestral Perl and sh scripts.  It should
+# be compatible back to Python 2.1.5.
+#
+# It is meant to be run either on a post-commit hook or in an update
+# hook:
+#
+# post-commit: It queries for current HEAD and latest commit ID to get the
+# information it needs.
+#
+# update: You have to call it once per merged commit:
+#
+#       refname=$1
+#       oldhead=$2
+#       newhead=$3
+#       for merged in $(git rev-list ${oldhead}..${newhead} | tac) ; do
+#               /path/to/ciabot.py ${refname} ${merged}
+#       done
+#
+# Note: this script uses mail, not XML-RPC, in order to avoid stalling
+# until timeout when the XML-RPC server is down. 
+#
+# Call with -n to see the notification mail dumped to stdout rather
+# than shipped to CIA.
