[PATCH] [docs] add cross-reference

[Renato Golin]

So, to test, go into the docs directory and type:

  $ sphinx-build -b html -d _build/doctrees . _build/html <DOC>.rst

This will generate the doc as it should, so you open the file in _build/html/<DOC>.html.

If your doc refers to another, you better generate both, so you can follow the link.
