      long_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 by David Abrahams: to minimize boilerplate code in traditional
  extension modules by inferring type information using compile-time
  introspection.
  
  The main issue with Boost.Python-and the reason for creating such a similar
  project-is Boost. Boost is an enormously large and complex suite of utility
  libraries that works with almost every C++ compiler in existence. This
  compatibility has its cost: arcane template tricks and workarounds are
  necessary to support the oldest and buggiest of compiler specimens. Now that
  C++11-compatible compilers are widely available, this heavy machinery has
  become an excessively large and unnecessary dependency.
  
  Think of this library as a tiny self-contained version of Boost.Python with
  everything stripped away that isn't relevant for binding generation. Without
  comments, the core header files only require ~4K lines of code and depend on
  Python (2.7 or 3.x, or PyPy2.7 >= 5.7) and the C++ standard library. This
  compact implementation was possible thanks to some of the new C++11 language
  features (specifically: tuples, lambda functions and variadic templates). Since
  its creation, this library has grown beyond Boost.Python in many ways, leading
  to dramatically simpler binding code in many common situations.""")
