[BioPython] cpairwise2module.c setup.py fun-ness

[Syd Diamond]

Good Sunday Morning Biopythoners,

I'm not a hardcore bioinformatician per se, but in a project the need came 
along to find database matches for strings with typos. I turned to 
biopython, found the pairwise alignment function, and heuristically set the 
parameters to find good alphanumeric matches. This is not the point of the 
post, but I thought it was a cool application of biopython.

Anyways, the c alignment module is significantly (2-4X) faster than the 
native python alignment module, and I was hoping to include this c module 
(cpairwise2) in a very low-key GPL distribution. I put in the biopython 
license file, and now I am trying to figure out a way to pare down the 
setup.py file to allow the user to compile the module.

I'm in over my head here. My python hack0r sk1llz are intermediate, but my 
gcc skills leave much to be desired. I have no idea where to begin.

In the biopython setup.py, I know cpairwise2 is simply one of the 
extensions.

** How should I reduce setup.py to only compile the cpairwise2 module?? **

Many thanks, yall.
