initial port from khan-dotfiles

essentially a straight copy, with repository metadata added.

the goal here is just to have these live somewhere that makes sense
conceptually and is easy to maintain, rather than being bundled as part
of our dotfiles setup.

+Collection of scripts in order to enable the [git workflow][git-at-ka]
+at Khan Academy. (see also: [arcanist])

+## Tools
+
+#### git deploy-branch
+Creates a remote deploy branch for use with GitHub-style deploys.
+
+For GitHub-style deploys, all work must branch off a deploy branch.
+
+#### git review-branch
+Creates a new local branch ensuring that it's not based off master.
+Such a branch is called a 'review branch'.
+
+All review branches should be based off a deploy branch.
+
+#### git recursive-grep
+Runs git grep recursively through submodules, showing file paths
+relative to cwd.
