Hi Axel,

My recommendation would be to 'prototype' in Ruby to establish the 
correct logic of what you want to achieve and then recode in C/C++ if 
speed is not fast enough - that's what we do for a number of things on 
our side.

If you don't use too many Ruby-isms, your Ruby code can look a lot like 
the corresponding C code - of course, you'd have to rewrite the string 
parsing in C/C++ to suit your needs.

Cheers
Mohit.
