Ah.  I had seen Gurobi's version, but I interpreted it more as a 
first-pass introduction to the LP format, rather than a complete 
specification or grammar.  CPlex's version seems a tad more thorough, 
but is still not complete by my understanding of a grammar.

In any event, I very much appreciate your code snippet.  I don't yet 
have that internal understanding of the GLPK code base to whip it out so 
quickly.  Is there any chance that will be included in the next GLPK 
release?

Cheers,
