A fs-module alike interface to a jsgit repo
This is a simple module to make a git repo appear similar to the object from
require('fs'), minus synchronous methods, and plus a commit method.
It's incomplete -- just read and write streams at this point, but it illustrates the concept.
var repo = ;var vfs = repo;vfs;processstdin;
Writing a file yields a hash; since it has a path associated with it, it will update an internal index, ready for commit.
The commit operation is atomic, via locking.
The write-file operation is idempotent.
Updating a tree is one atomic operation per level of the tree. Writing different data to the same path simultaneously will yield different trees depending on the order of the end events.
