SWIG

<>SWIG is a software development tool that connects programs written in C and C++ with a variety of high-level

programming

  languages. SWIG is used with different types of languages including common scripting languages such as

Perl

 ,

PHP

 ,

Python

 , Tcl, Ruby and

PHP

 .
In a nutshell will parse C/C++ headers and creates a binding. (they need to be clean headers).
Generating a binding is never an easy task but swig makes it a little simpler.
