[Help-glpk] LP files and machine-parseable sensitivity output?

[Kevin Hunter]

Hello List,

I have a program that spits out LP files, which I then give to GLPK via 
the --lp command line argument.  Is there a machine-friendly version of 
--ranges?

Since learning about the tandem use of --write and --wglp via the 
Wikibooks Interoperability page[1], I'm now wishing I had a similar 
format to work with for the sensitivity information.  As I'm limited to 
LP files as my only means of input to GLPK, GMPL is not an option for 
me.  Is there a file-based avenue for acquiring machine-parseable 
sensitivity information from GLPK that I have not yet discovered?

Thanks,

Kevin
