I think Nathann Cohen has done a very valuable service with the GLPK and COIN-OR-related packages.
That said, I have a "point of order" question. Is is true or false that the process for a package to become standard we (1) use trac to do nomination, testing, and acceptance as an optional package, (2) someone (William say) posts the spkg to http://www.sagemath.org/packages/optional/, (3) after a period of a few months, voting is done for making it standard. In any case, I vote +1 for Nathann's GLPK spkg being moved to optional and the currently posted GLPK spkg on experimental removed, with the idea that it be proposed for inclusion as a standard package. If the above process is correct then there is nothing more to say. If not, I think someone (not me) look into this PyGLPK (I am not an OR person and have never heard of this before). By compare, I mean, look at the license, compare Nathann's wrappers and docstrings to PyGLPK's, etc. Maybe there are other wrappers on the internet (I have not done a google search, just mentioning possibilities here.)
