Just an old version of GST.

This is the same as creating bindings for a library such as SQLite or 
GTK+ or NCurses.  There are several examples of varying complexity in 
the GNU Smalltalk distribution.

_gst_process_file works.  If the file is just a bunch of class and 
method definition, it won't block.

If the main program is written in Smalltalk, you actually want to make 
it blocking though.

You can feed everything you want, you may get a #doesNotUnderstand: if 
you screw up.
