New description:
The GNU Linear Programming Kit (GLPK) provides functions to which SAGE
currently does not provide access. These include:
* Sensitivity analysis
The following enhancements might be helpful:
* Access to glp_print_ranges to store results of a sensitivity analysis
in a file
* Access to GLPK function for getting shadow prices and reduced costs
