My aim for a tool like this would be able to take some random library that
registers some stuff with glib's type system, and have the tool output
defs information.

As inputs, we need to know how to initialise the library (if it requires
any initialisation above a simple g_type_init()), and all the get_type()
routines.  Yes it would be possible to drive this stuff through python,
but then you would need a binding for the library that included a way to
call the library initialisation, and a way to access all the get_type()
functions or variables holding GTypes.

This module would need to be an extension module for python, and
generating it would be more work than generating a simple C/C++ program as
I proposed earlier.
