First read section 6 in the FAQ. Then download the source code: there 
are examples of C++, C, Python and Perl solvers in the utils/solvers 
directory.

No, "Custum Filter" just defines a filter for selecting the filenames 
(it's a default thing in the FLTK file chooser).

If you want to create a new output format, you'll have to modify the 
source code.

Take care,
