I noticed that your announcement of the next version also seemed to  
mention something about this.

Would it be possible to point me to an existing example of doing  
this?  Or any hints about how to do it myself?

I'm relatively new to python, so I have to admit I don't grasp the  
significance of what this page describes.  Again, some simple  
examples of wrapping C code would really help me understand how I  
could use your tools.

Well, in the mean time I have in fact found a way to tweak the xml2py  
script of ctypeslib, and I've announced the patch on the ctypes-users  
mailing list, which I can forward to you if interested.  So ctypeslib  
is working again for me, with gcc 4.0.1 and gccxml 0.9.0, but there  
are probably still some small problems.

I do think it would be very good if ctypeslib is still maintained by  
someone.  To me it seems like a tool that is very good at its one  
thing, and its a shame when those tools stop working.  Alternatively,  
from what I understand, it seems like the pygccxml output could also  
be parsed to generate the same ctypes code that ctypeslib generates-  
that is, the brains of ctypeslib's xml2py script could operate on the  
pygccxml parse tree instead of the XML file directly.  But I barely  
know what I'm talking about!

thanks,
