Subject: docs: add bootstrap extension
X-Git-Tag: upstream/23.3.3~9454
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f72033bb707046ef5966cb55cbf9bd9fb7bb038f;p=platform%2Fupstream%2Fmesa.git

docs: add bootstrap extension

To get Sphinx and Bootstrap to work well together, we need to massage
the output from Sphinx a bit. This adds an extension to do such changes,
based on work from here:

https://github.com/pydata/pydata-sphinx-theme

...However, because we don't ship as an external theme, we can't just do
things as a part of __init__.py, so instead we register an extension
that does the heavy lifting for us.
