GEMPAK/Python interface

My wife uses the gemlib functions in her work as a student to access 
grid files.  In order to do this, she, of course, uses FORTRAN.  
However, she wanted to use some functionality of the Python 
(http://www.python.org) language as well in these programs, but there 
really wasn't an efficient/easy way to do this.  If you aren't familiar 
with Python, it is a very simple to use, but very powerful scripting 
language (similar to Perl, but not as ugly :) ).  After doing some work 
on this and working with the developer of F2Py 
(http://cens.ioc.ee/projects/f2py2e/) to iron out some problems, I was 
able to successfully wrap several gd functions and create a very easy 
to use Python interface to grid files with very little work.  I don't, 
however, have the GEMPAK expertise to do a complete interface to all of 
GEMPAK's functionality, and thought that I would present my work to you 
in case you wanted to continue this work.

The basic process of creating Python interfaces is:
    - Add f2py directives to FORTRAN files to guide f2py in creating 
interface files
    - Run f2py on the FORTRAN files to create the Python interface
    - Write Python class wrappers around GEMPAK functions to give them 
a more object oriented presentation

I've included a tar file of the the gd*.f files, as well as inbdta.f, a 
small build script, and a Python module that wraps the gd functions in 
a "Pythonic" way (see the comments at the top of gempak.py for examples 
of it's usage).  If you have any questions, please let me know.
