Whether NULL is allowed for a parameter, whether a parameter may default and
if so what value should be used, whether a parameter is a return value, etc,
all of these are described in pygtk's defs files, and i believe in gtkmm's as
well.  None of that form of info is in the headers; it usually comes from
manually digging through source code and documentation.

Not that many hours ago i sat here writing about how the API definition need
to include *more* metadata of this sort....  see
http://lists.gnome.org/archives/language-bindings/2004-March/msg00062.html

That thread mentioned switching to a more detailed XML format for the defs.  I
think that's A Good Idea; binding code generation would simply be an exercise
in XSLT.  :-)
