[sage-devel] Automated Downloading of Most Recent Version of Sage

I have written an sort of experimental package for Sage and I am currently using TravisCI to run my tests. Since TravisCI doesn't have an installation of Sage I decided to make downloading it a step in the travis.yml config, in particular, during the before_install step: wget http://mirrors.mi
