If you're packaging your library for redistribution, you should indicated the Python interpreter your library is compiled for by including the [platform tag](#platform-tags) in its name. This prevents incompatible interpreters from trying to import your library. If you're compiling for PyPy you *must* include the platform tag, or PyPy will ignore the module.
