I would like to introduce you lovely OpenSource Lovers to a GIT-Alternative called FOSSIL that I also stumbled upon. It's basically opensource Github-in-a-box which means it's an SCM with:

• Bug-tracker
• Ticketting-system
• Forum
• Wiki-system
• even a Chat-functionality

& It's also self-hostable & the best part it's all in ONE STANDALONE FILE!!! how cool is that

However this tool supports a completely different style of development in FOSS called the "Cathedral-Style" whereas GIT suports a "Bazaar-Style" The person behind Fossil is the creator of SQLite, Dr.Richard Hipp & they even made other projects to support Fossil like a PIC-Like language called PikChr

Well here's a difference between Git vs Fossil & they even have a hosting service called CHISEL

Just check it out & use it for fun in your spare time even with the flaws it has (& Try out Darcs & Pijul as well)
