Comment 5 for bug 219334

It seems to me that we won't stop using rst anytime soon so, since:
- we are already moving to sphinx for the web site,
- sphinx is used by the python project and as such is the most likely candidate to be used for the
  bzrlib documentation (which AFAIK is produced only partially and punctually as of today),

we'd better look at helping the sphinx project produces a texinfo builder/writer.

From http://<email address hidden>/13813064.html, I understand
that it shouldn't be that hard so I'll look into starting a bzr-specific one and see how it turns out.
