"""hooks for integrating with the CIA.vc notification service
This is meant to be run as a changegroup or incoming hook. To
configure it, set the following options in your hgrc::
[cia]
# your registered CIA user name
user = foo
# the name of the project in CIA
project = foo
# the module (subproject) (optional)
#module = foo
# Append a diffstat to the log message (optional)
#diffstat = False
# Template to use for log messages (optional)
#template = {desc}\\n{baseurl}{webroot}/rev/{node}-- {diffstat}
# Style to use (optional)
#style = foo
# The URL of the CIA notification service (optional)
# You can use mailto: URLs to send by email, e.g.
# mailto:cia@cia.vc
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False
# number of slashes to strip for url paths
#strip = 0
[hooks]
# one of these:
changegroup.cia = python:hgcia.hook
#incoming.cia = python:hgcia.hook
[web]
# If you want hyperlinks (optional)
baseurl = http://server/path/to/repo
