G3 F2PY library package

Overview
========
The G3 F2PY library package contains tools to parse Fortran codes and
construct Python C/API extension modules for wrapping Fortran
programs. These tools are also suitable for implementing Fortran
program translators or wrappers to any other programming language. In
fact, wrapping Fortran programs to Python would be one example of
using these tools.
Wrapping Fortran with Python
============================
There are two user interfaces to wrap Fortran programs with
Python:
- the command line program `f2py` that scans Fortran files
given as command line arguments and builds extension modules
that can be used to call Fortran programs from Python.
The `f2py` program has four different ways of building
extension modules as specified with the following command
line flags:
- `--g3-numpy` --- create extension modules with NumPy array
support using the new tools from `the 3rd generation of F2PY`__.
This is a work-in-progress feature.
- `--2d-numpy` --- create extension modules with NumPy array
support using `the stable version of F2PY`__. This is default.
- `--2d-numeric` --- create extension modules with Numeric
array support using the old version of f2py2e. The f2py2e
package must be downloaded and installed separately from
the `f2py2e homepage`__.
- `--2d-numarray` --- create extension modules with Numarray
array support using the old version of f2py2e.
See the output of `f2py` for more information.

- the function `compile()` that scans its string input containing
Fortran code and returns a list of imported extension modules
that can be used to call Fortran programs from Python.
