Hi, it occurred to me that the new entry in the help menu says "Linear programming", whereas the document is called "gretl + lpsolve". This is in contrast to "gretl + MPI". Of course this isn't very important, but some harmonization would still be good. No strong preference about which way to go, though. Related to that, maybe it could help to explain the abbreviations in the menus, like "gretl + MPI (parallelization)" or "gretl + SVM (support vector machines)". cheers sven
