[PyKDE] Help on wrapping a C library

[Huaicai Mo]

Roberto,

Thank you for the reply. Initially, I planned to use SWIG, which was used to
create the PyOpenGL package, but I read the article:
http://people.web.psi.ch/geus/talks/europython2004_geus.pdf	

It looks to me SIP has better performance, but I am not sure if that's only
true for C++? I didn't see any known packages wrapped by Pyrex, did you?
