velma

Velma is the reimplementation of vera python-API built with C internals.

main differences

• Velma suppports python-based plugins while vera support both lua and python.
• It provides a python package built with setuptools and C extension rather than relying on <boost/python.hpp>. This avoid relying on the system python environment, and provide support for virtual env.
• Tokenization is done with C in mind rather than C++.
