+1 from me to start having manuals in reStructuredText format and
then converting these to the target formats. Some comments on
the patch series below:

Building any docs using this is not yet activated ?

Anyway, I tried to build manual pages using 'make man' and got this:

  $ make man
  sphinx-build -b man -d doc/_build/doctrees -q -c doc doc doc/_build/man
  Making output directory...

  Sphinx error:
  Builder name man not registered

No fallback to use rst2man...

Style! run pep8 prerst2html.py and fix the issues it prints
to the screen, like ' = ' above and remove trailing semicolon
below... (and also pep8(1) doc/conf.py.

For python < 2.7 these needs to be {0:s}, {1:s}, {2:s}.. {5:d}...

Replace date.today.isoformat() with date determined from other
sources (NEWS file?)

In addition to formatting above, use either ".rst" or '.rst'
(and perhaps other quotations in these 2 lines) for consistency.

pep8 will in the lime above (as it is not lines[0:count + 1])
I might not have complained but... :D
