Wrapping dia interfaces to enable in Python

[Carol Farlow Lerche <cafl msbit com>]

This is probably an inappropriate suggestion to people who know way more 
than I do about Dia.  But I have used SWIG (http://swig.org) very 
successfully to provide a complex C library as a Perl-accessible 
interface in the past, and it also supports Python.  It didn't take very 
long to figure out how to use it.  You basically feed it the .h files 
along with additional guidance as needed, and it emits a shim layer for 
mating the (Perl/Tkl/Python/Guile/Java/Ruby/Mzscheme/ 
PHP/caml/C#/chicken scheme/javascript/eiffel) scripting language to the 
underlying C or C++ library.

Of course you have issues with mating the data types, but these can be 
worked out pretty easily.
