Provides a "git export" command similar to "svn export" that exports the current index (including all submodules) to the target path.

git-export

#!/bin/bash
#
# Place this in your executable path (e.g. "~/bin/git-export")
# and you should now be able to go: git export [path]

PWD=$(pwd)

# Exit on error (e.g., "Not a git repository")
set -e
TOP_LEVEL=$(git rev-parse --show-toplevel)
set +e

REPO_NAME=$(basename "$TOP_LEVEL")

if [[ -z "$1" ]]; then
	cat <<- USAGE

		  Usage:
		    git export [path]

		  Where:
		    [path] is the folder to export to (will export to "[path]/$REPO_NAME")

pushd "$RAW_TARGET" >> /dev/null
TARGET_FOLDER=$(pwd)
