lp_solve is a free linear programming and integer programming solver. The
library is written in C, but the developers provide bindings to several
languages, including Python.
I have created an spkg for installing lp_solve into Sage. The spkg is
located at:
http://www.math.unl.edu/~shartke2/files
All tests passed on my intel mac (10.4).

Built fine, tested fine with one non-repeatable so far "time-out", in
plot.py - seems time-out is also reason for 2 failures mentioned on
that 32bit fedora... (looking at that version that passed, 335 seconds
is quite some)...
is there already command-line option to set longer times on slower

I _speculate_ that the relationship is that all the editors are also

What exactly is the relationship between that journal and Macaulay 2?
Or between it and Sage, apart from its one-letter-too-short acronym?
