description     GNU Linear Programming Kit

long_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.
