In glpk v4.43 there exist three api routines to write the problem
object to a text file: glp_write_prob, glp_write_mps, and glp_write_lp.
Corresponding glpsol options are: --wglp, --wmps or --wfreemps, and
--wlp, resp. For more details please see the reference manual included
in the glpk distribution.
