    A Sugestion for scripting. There are some good scripting languages for linux
    available in source code format that are designed to be added in to existing
    programmes to give it a script ability. This would save the development of
    any preprocessors/parsers as these are already implimented. As they are in
    source code and not GUI dependent they should be easily portable to WIN
    platforms.

    The code is also FREE GNU public licence and as Femm is non comercial there
    should be no problem using it
