I have been maintaining Pritlog versions using manual versioning. Recently, I started looking into moving Pritlog into a proper version control system for easier development and sharing. Pritlog was already on Google code (SVN), then I tried Git (on private VM, Github and Gitorious).
After my experiments with Git which I was very satisfied with, I came across couple of other version control systems - Fossil, Monotone. I tested both these and am currently considering using Fossil. You can read all about this scm at http://fossil-scm.org
Its an amazing software. It is under 1 MB, is self contained and includes a wiki, bug tracking system and a web server. Its very easy to install a fossil repository on a shared hosting. Setting up Git or other SCM's on a shared hosting can be difficult and in some cases impossible. Its from the creator of SQLite.
So now, Pritlog is officially on Fossil. You can see it here -

But, I still have the source on Github, Gitorious and a private vm. I might remove these later.
