Homepage is unclear how to contribute to Eigen
I found a small issue in Eigen and thought that I'd make a patch. On the home page I clicked "contributing to Eigen," which in turn linked me to the following page: http://eigen.tuxfamily.org/index.php?title=Mercurial
That page mentions Mercurial, which I don't use, bo I decided not to do anything. However, I later found this repo which seems to suggest that Gitlab and git are in fact used. If so, the wiki needs to be updated.
