Summary: GIT - the stupid content tracker, the revision control system heavily used by the Linux kernel team

Git

Git is a revision control system used extensively under funtoo linux, and kernel.org. It is a distributed revision control system with a work flow that breaks away from the traditional client ----> server model to the git <--> git model. revision control means that the program operates like a progress save state in a game. you can save at the start of the game, mid way through, and at the final stage. if you desire to do sub quests you can load up the mid save point and then explore other areas of your code. git is suitable for just about everything regarding text. git is a bad choice for frequently changing binary files.
