You can start by looking at what we do with the --disable-gui
configuration option (i.e., look at the alternative main() in Mesh/Box.cpp).

But, frankly, at the moment, I wouldn't advise you to start such a job
if you don't feel really comfortable with sources: the current version
of Gmsh is still based on the "old" mesh database (not AOMD) and the
meshing kernel has thus many dependencies against the CAD stuff, it
relies on static data structures all over the place, etc., etc.

We will eventually clean up the mess, but it will take some time. And
Jean-Francois and I can only spend a *very* little percentage of our
time on this project... So don't hold your breath ;-)

Best,

Christophe
