-	GIT has a commit snapshot which points to a tree; tree has entries and each points to another tree or a blob (file)
	Mercurial stores Manifests with all the files in the tree and their version; it stores this as deltas; manifest doesn't track dirs,

	Mercurial ecnourages branching via cloning. It has permanent named branches in a single namespace. It has bookmark feature a bit similar to lightweight branches
