Good point. 
One other note, the C version should have a much smaller memory footprint then
Perl or Python - less likely to perturb test results. 
Speaking for myself, i think this is such a small pile of code, it might be fun
to have a parallel Perl/Python version. (it would be a good excuse for me to 
learn some Python)
My personal choice would be C to generate the data and Perl to pretty-print 
it.

 I need to get into the code more for STP integration, so i'll have more 
opinons
soon :)
