If you would like to be able to parse GMPL models
(GMPL is a subset of AMPL), you will need to install GLPK
(http://www.gnu.org/software/glpk/). To do so automatically, run the
get.Glpk script in the ThirdParty/Glpk directory. After
that, Glpk should be built and linked automatically, enabling the ability to
read GMPL files.
