"""CIA notification

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}/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, eg
# mailto:[e-mail]
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False

[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
