#
# 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
#
# usage: ciabot.py [-V] [-n] [-p projectname]  [refname [commits...]]
#
# This script is meant to be run either in a post-commit hook or in an
# update hook. Try it with -n to see the notification mail dumped to
# stdout and verify that it looks sane. With -V it dumps its version
# and exits.
#
# In post-commit, run it without arguments. It will query for
# current HEAD and the latest commit ID to get the information it
# needs.
#
# In update, call it with a refname followed by a list of commits:
# You want to reverse the order git rev-list emits because it lists
# from most recent to oldest.
#
# /path/to/ciabot.py ${refname} $(git rev-list ${oldhead}..${newhead} | tac)
#
# Configuration variables affecting this script:
#
# ciabot.project = name of the project
# ciabot.repo = name of the project repo for gitweb/cgit purposes
# ciabot.xmlrpc  = if true (default), ship notifications via XML-RPC
# ciabot.revformat = format in which the revision is shown
#
# ciabot.project defaults to the directory name of the repository toplevel.
# ciabot.repo defaults to ciabot.project lowercased.
#
# This means that in the normal case you need not do any configuration at all,
# but setting the project name will speed it up slightly.
#
# The revformat variable may have the following values
# raw -> full hex ID of commit
# short -> first 12 chars of hex ID
# describe = -> describe relative to last tag, falling back to short
# The default is 'describe'.
#
# Note: the CIA project now says only XML-RPC is reliable, so
# we default to that.

# By omitting $files you can collapse the files part to a single slash.
