toolkit, but can be used to create bindings for any C or C++ library.

SIP comprises a code generator and a Python module.  The code generator
processes a set of specification files and generates C or C++ code, which
is then compiled to create the bindings extension module.  The SIP Python
module provides support functions to the automatically generated code.")
