Yeah, no problem. The ordering is kept, since the exporters are kept in 
a list.

So, how about this interface:

add_include('header1', 'header2', 'header3')
add_code(MODULE, <code>)
add_code(DECLARATION, <code>)
add_code(GLOBAL_DECLARATION, <code>)  # outside the namespace generated 
by pyste.
                                      # Any suggestions for a better name?

Does it cover all the needs, or am I missing something? 8)

I plan to work on this tomorrow, or perhaps a little today. Any 
suggestions are appreciated!!

Nicodemus.
