"""
|

* adds github_link(mode) context variable: provides URL (in relevant mode) of
|
|
current document on github
|
|
* if sphinx.ext.linkcode is enabled, automatically generates github linkcode
|
|
links (by setting config.linkcode_resolve)

Settings
|
|
========
|
|
|
|
* ``github_user``, username/organisation under which the project lives
|
|
* ``github_project``, name of the project on github
|
|
* (optional) ``version``, github branch to link to (default: master)
|
|
|
|
Notes
|
|
=====
|
|
|
|
* provided ``linkcode_resolve`` only supports Python domain
|
|
* generates https github links
|
|
* explicitly imports ``openerp``, so useless for anyone else
