Re: [Texmacs-dev] Scheme interface for the graphical mode

[Massimiliano Gubinelli]

Dear Giovanni,
 procedures declared with tm-define are visible globally, while procedures 
declared with define are only visible within the module. I think this answers 
your question.

Of course in the future it is possible to imagine to enhance the module with 
additional procedures, useful for graphic programming, but for the moment I 
think would be better to experiment with code external to the main code-base.
