Somewhat similar to "svn info" but for a Git checkout

git-info.sh

#!/bin/bash

#
# Displays information about the current working copy of a Git checkout
# and how it relates back to the remote branch it is tracking (if there is one)

adding

cd `readlink -f .`

before

while [ ! -d .git ] && [ ! `pwd` = "/" ]; do cd ..; done

allows you to find the real "Working Copy Root Path".
