 %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.
