I need the full pathname to compute the checksum. How do I suggest I
find it out then? Should I iterate over supported extensions until I
find the correct one?

Out of curiosity, what will it be?

Attached. I assumed most distutils users are not familiar with passing
options to distutils' subcommands, so I elaborated on it a little.

 As we can see, the above is a normal distutils setup script, with just a
 special line which is needed so that SIP can see and process ``word.sip``.
 Then, running ``setup.py build`` will build our extension module.

+If you want to use any of sip's command-line options described in
+:ref:`ref-command-line`, there is a new option available for the
+``build_ext`` command in distutils: ``--sip-opts``. So you can either invoke
+distutils as follows::
+
+     $ python setup.py build_ext --sip-opts="-e -g" build
+

+file in the supported system or local paths (eg: in the same directory of
+``setup.py``) with these contents::
+
+     [build_ext]
+     sip-opts = -e -g
+
+and then run ``setup.py build`` as usual.
