minerjoe is mentioning Fossil specifically because unlike Git it also provides the features (in a broad sense) that GitHub provides (wiki, bug tracker, discussion forum, news/blog, "released" files and of course version control) while remaining fully distributed - these are stored and versioned as part of the repository itself.

As a nice bonus Fossil is a single executable/binary file you can drop anywhere and can act as both the CLI for working with the repository and as the web backend with a bunch of ways to access it including CGI, it's own web server or even as a fake script parser (you can upload the linux binary to any shared host that supports custom script parsers -many do- and use a "script" with a shebang that calls the binary with the path to the repository file, thus allowing you to use Fossil with shared hosting services that do not even know about it).
