-
-    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
