%description
The GLPK package is a set of routines written in ANSI C and organized
in the form of a callable library. This package is intended for solving
large-scale linear programming (LP), mixed integer linear programming
(MIP), and other related problems.

The GLPK package includes the following main components:

* implementation of the simplex method;
* implementation of the primal-dual interior-point method;
* implementation of the branch-and-bound method;
* application program interface (API);
* GNU MathProg modeling language (a subset of AMPL);
* GLPSOL, a stand-alone LP/MIP solver.

See GLPK webpage <http://www.gnu.org/software/glpk/glpk.html>.
