My plan is to make separate ctypes releases for 2.3 and 2.4, even after
it is integrated into Python 2.5, so it seems [2] would be better - it
must be possible to build ctypes without Python.

As I said before, docs need still to be written.  I think content is
more important than markup, so I'm writing in rest, it can be converted
to latex later.  I expect that writing the docs will show quite some
edges that need to be cleaned up - that should certainly be done before
the first 2.5 release.

Also I want to make a few releases before declaring the 1.0 version.
This does not mean that I'm against integrating it right now.

Hye-Shik has done a great job!  Many thanks to him for that.
