New description:
This ticket upgrades lrslib to version 6.2. This version, according to
http://cgm.cs.mcgill.ca/~avis/C/lrs.html, has the following new features:
- (new in 6.0) mplrs: C wrapper for lrs that allows for parallelization
on clusters of machines and uses the MPI library quickstart
- (major revision in 6.1) lrsnash, 2nash: Computes all Nash equlibria of
a two person non-cooperative game. 2nash is a 2-processor parallel
version
Since Polymake (#20892) seems to need the shared library of lrslib, but
lrslib uses a hand-written makefile that does not work on Mac OS X, I have
added an autotools build system. It is available here:
https://github.com/mkoeppe/lrslib/tree/autoconfiscation
