A number of virtual hosts are supported on this web server. There are a few odds and ends that didn't fit anywhere and ended up as subdirectories here. Most are old content that lacks a home. There is no index of this stuff and its hoped that no one runs into it except perhaps anyone that knew of it and asked where it lives now. Most content on this virtual server is in the uncertain state of either being supported in the future if there is interest in it or otherwise tossed entirely.
