Old releases of Multigraph in a github repo, for hosting on github pages.
The gh-pages branch of this repo contains files that will appear at http://multigraph.github.com/archive. That URL looks like it's part of the same site as http://multigraph.github.com, but it's managed separately in this repo, in order to keep the size of the down.
To add files to the archive, commit them to the gh-pages branch of this repo, update the index.html file, and push to github. The result will show up at http://multigraph.github.com/archive.
