@hackage cpython3.1.2.0

These bindings allow Haskell code to call CPython code. It is not currently possible to call Haskell code from CPython, but this feature is planned.

Please note that this library uses a somewhat abnormal versioning scheme; the first two version numbers are the CPython version, the third is the package's major version, and the fourth is the package's minor version. For example, the package version 3.1.1.0 binds to CPython 3.1, and has a package version of (1, 0).
