"""pybind11 -- Seamless operability between C++11 and Python.
 
 
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."""
