Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
libcerf could not be built reproducibly.

This is because the manual pages embedded absolute build path in the
title of the page.

A patch is attached that specifies a specific, deterministic title to
pod2man, thus making the build reproducible.

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed that
zzzeeksphinx was generating output that was not reproducible.

This is because the template includes:

    % if show_sphinx:
        Created using <a href="http://sphinx.pocoo.org/">Sphinx</a> ${sphinx_version|h}.
    % endif

    Documentation last generated: ${datetime.datetime.now().strftime("%c")}
                                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This was affecting the reproduciblity of (at least) the mako in
Debian. A patch is attached that makes this use SOURCE_DATE_EPOCH
instead.
