A Sphinx extension to reference issues in issue trackers, either explicitly
with an "issue" role or optionally implicitly by issue ids like #10 in plain
text.
Currently the following issue trackers are supported:
* GitHub
* BitBucket
* Launchpad
* Google Code
* Debian BTS
* Jira
A simple API is provided to add support for other issue trackers. If you
added support for a new tracker, please consider sending a patch to make your
work available to other users of this extension.
