"""zest.releaser entry points to support projects using distutils2-like
setup.cfg files. The only actual functionality this adds is to update the
version option in a setup.cfg file, if it exists. If setup.cfg does not exist,
or does not contain a version option, then this does nothing.
TODO: d2to1 theoretically supports using a different filename for setup.cfg;
this does not support that. We could hack in support, though I'm not sure how
useful the original functionality is to begin with (and it might be removed) so
we ignore that for now.
TODO: There exists a proposal
(http://mail.python.org/pipermail/distutils-sig/2011-March/017628.html) to add
a 'version-from-file' option (or something of the like) to distutils2; if this
is added then support for it should be included here as well.
