Git is an open source, distributed version control system implemented 
as a directed acyclic graph of commit objects pointing to snapshots
of content, with all data saved in it's own custom content addressable
filesystem by the SHA-1 checksum hash of each objects data.  branches 
are simply pointers into this directed graph of commits, identifying
entry points that designate the latest work on that branch, allowing
Git to traverse the pointers, determining a coherent history.  
this makes branching cheap and easy, and merging simple, encouraging 
non-linear development styles and frictionless context switching while 
facilitating distributed development, cryptographic integrity and late
