I haven't tried this, but from looking at the code,
Martin can use the same escapes in his definition of install_headers,
e.g. install_headers = $base/MyIncludes
 
I'm not sure about the collection of variables available for
expansion (they are scattered all over distutils), but at most of
them follow the naming scheme used in the standard Python Makefile,
so their names should be easy to deduce.

Hmm, the build commands do respect the settings in the setup.cfg file,
but the installer itself doesn't.

It would be nice, if the wininst installer would allow even more
flexibility, e.g. allow setting the install directory (this would
then have to generate a .pth file to properly setup the Python path),
optionally generating a "click to accept license" box and
an optional "misc notice" box (for arbitrary additional information
which wouldn't fit into the standard description box).

Thomas Heller has already done a fantastic job here, so these are
really only minor nits.
