Module Name:    pkgsrc

Log Message:
GLPK 4.49 (release date: Apr 16, 2013)

        The new API routine glp_mincost_relax4, which is a driver to
        relaxation method of Bertsekas and Tseng (RELAX-IV), was added
        to the package. RELAX-IV is a code for solving minimum cost
        flow problems. On large instances it is 100-1000 times faster
        than the standard primal simplex method. Prof. Bertsekas, the
        author of the original RELAX-IV Fortran code, kindly permitted
        to include a C translation of his code in GLPK under GPLv3.

        A bug (wrong dual feasibility test) was fixed in API routine
        glp_warm_up. Thanks to David T. Price <>
        for bug report.

        Obsolete API routine lpx_check_kkt was replaced by new routine

        IMPORTANT: All old API routines whose names begin with 'lpx_'
        were removed from API level and NO MORE AVAILABLE.
