GROOT - go to the "git root"

groot.sh

#!/bin/bash
# GROOT! v 1.0.0
# Install in your dotfiles, .bashrc, .zshrc or similar

# No more cd ../../../../.. to get to the root of a git project
# Running the command "groot" will look for the closest .git directory and take you there.
# Note that it doesn't traverse up the tree, it takes you directly to the directory with a .git in it...
# ...so the command `cd -` takes you back to where you were.
# Works with *some* submodules (depending on how your submodule was setup - as a file or a dir)
# If you are using submodules, you should be able to figure out how to modify this.
# If you are using submodules, but you CAN'T figure out how to modify this, go here: http://goo.gl/nI0zLc
