The reasons SIP hasn't gained more attraction are dark to me. At least 
when it comes to C++, it's support is waaay better than SWIG. There also 
exists some Boost Python stuff, but I never wrapped my head around that.

However, if you are "only" wrapping C, pyrex is my tool of choice. It 
has build-in distutils support, and it is very easy to write. So if you 
can, go with pyrex. If you must wrap C++, go with SIP - boost
