I have updated the lp_solve spkg to the latest version, lp_solve 5.5.0.14. I have also included the documentation files, which I install into $SAGE_LOCAL/share/doc/lp_solve-5.5.014. Is this the correct location for documentation files? The updated spkg is located at http://www.math.unl.edu/~shart

Everything of lp_solve is LGPL, so also the documentation. And there is an index.htm Peter On Apr 13, 12:34 am, David Joyner wrote: > On Sun, Apr 12, 2009 at 6:13 PM, peno wrote: > > > Onhttp://lpsolve.sourceforge.net/5.5/, there is in the index left an > > item 'Download' > > That directs yo
