I assume you mean assembler.  Anyway, as of Python 2.5 you *can* 
directly access the DLL using ctypes.  PyOpenGL is just a convenience 
wrapper around that functionality.  That is, you can simply import 
ctypes, load the library and start calling functions in it.

http://pyopengl.sourceforge.net/ctypes/using.html

Has as clear a set of instructions as I currently have on hand.  If 
you're getting stuck somewhere, please let us know *where* and I'll try 
to clarify the documentation.

I don't even know if it would work with a .egg based distribution, I'll 
have to look into that.  I liked the installers too when I used to use 
Windows (way back when).  Guess I've gotten a bit out of touch with the 
Win32 world.

Really?  I always preferred it when planning to create stand-alone 
projects.  That said, it's not yet .egg friendly either.

If you want click-to-run functionality you'll need to script it yourself 
at the moment.  Setuptools doesn't AFAIK have a GUI installation 
mechanism on Windows.  Basically the setuptools/.egg stuff turned out to 
be less mature than I believed and we're still working through getting 
the tools built to support it.

The BSD-style license we use is far less restrictive than the GPL.  As 
such it allows a wider range of projects to use the library.  In 
particular, it allows commercial projects to use the library without 
GPL-style "viral" restrictions.

Take care,
Mike
