Git OctoCat
Git allows multiple coders to develop a piece of software at the same time by creating distributed source files, which can be edited offline from multiple locations, and then allowing authors or “committers” to commit changes to the main document, or create branches of the master document where code can be edited, then cleaned up, and merged. This system allows for a detailed documentation of code changes by multiple authors, so that it is possible to backtrack to previous versions, and make corrections where necessary.
