The GLPK code is spread across two source files (btw, in English,
source code is a mass noun, like help and information, there are no
helps, no informations and no source codes):

     
http://hg.savannah.gnu.org/hgweb/octave/file/tip/scripts/optimization/glpk.m
     
http://hg.savannah.gnu.org/hgweb/octave/file/tip/src/DLD-FUNCTIONS/__glpk__.cc

As you can see, the argument parsing is handled in glpk.m but the
actual work is done in __glpk__.cc. I am not familiar with GLPK to
tell you how difficult it would be to add more functionality to the
code, but I can help you with the infrastructure of writing and
committing a patch if you would like.
