I just bumped into this today while testing v2 of my
content-description series:

  $ ./configure
  …
  $ make
  …
  python ./doc/mkdocdeps.py ./doc doc/_build doc/docdeps.mk
  Traceback (most recent call last):
    File "./doc/mkdocdeps.py", line 6, in <module>
      execfile(srcdir + '/conf.py')
  NameError: name 'execfile' is not defined
  …

The first patch in this series fixes that issue, and the rest of the
series fixes some other issues I bumped into while working on that.
Sorry I missed these in the initial series.

Note that while mkdocdeps.py and prerst2man.py are now Python 3
compatible (with this series), the build will fail for Python's 3.0
through 3.2 because of the explicit unicode literals in conf.py [1].
It's likely that conf.py could use [2]

  from __future__ import unicode_literals

drop the u'' prefixes, and be compatible with all Python's ≥2.6
(including all 3s).  I haven't checked the logic though, and I'm not
running 3.2 locally anymore, so it's not a big priority for me.

Cheers,
Trevor
