SUMMARY="Seamless operability between C++11 and Python"
DESCRIPTION="pybind11 is a lightweight header-only library that exposes C++ \
types in Python and vice versa, mainly to create Python bindings of existing \
C++ code.
Its goals and syntax are similar to the excellent Boost.Python library by \
David Abrahams: to minimize boilerplate code in traditional extension modules \
by inferring type information using compile-time introspection."
