ones, make sure the new files included in the match patterns in

:file:`MANIFEST.in`, and/or in `package_data` in `setup.py`.

C/C++ extensions

* Extensions may be written in C or C++.

* Code style should conform to PEP7 (understanding that PEP7 doesn't

address C++, but most of its admonitions still apply).

* Interfacing with Python may be done either with the raw Python/C API

or Cython. Use of PyCXX is discouraged for new code.

* Python/C interface code should be kept separate from the core C/C++

code. The interface code should be named `FOO_wrap.cpp`.

* Header file documentation (aka docstrings) should be in Numpydoc

format. We don't plan on using automated tools for these

docstrings, and the Numpydoc format is well understood in the

scientific Python community.
