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

GLPK supports the GNU MathProg language, which is a subset of the AMPL
language.

The GLPK package includes the following main components:

 * Revised simplex method.
 * Primal-dual interior point method.
 * Branch-and-bound method.
 * Translator for GNU MathProg.
 * Application program interface (API).
 * Stand-alone LP/MIP solver. 

The library is available as 32-bit and 64-bit.

%description devel
The glpk-devel package contains libraries and headers for developing
applications which use GLPK (GNU Linear Programming Kit).

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".
