First pass at creating a bash script to overload additional commands onto svn

svn.sh

#!/bin/bash
B="\033[1;7;32m"
R="\033[0m"

COMMAND="$0"
COMMAND=${COMMAND##*/}
ORIGINAL="$(which -a $COMMAND | grep -vE "^$0$" | head -1)"

case $1 in
	'')
		echo -e "${B}svn is overloaded.$R"
		$ORIGINAL
		;;
	help)
		case $2 in
			'')
				$ORIGINAL help
				echo -e "${B}Overloaded subcommands available:$R"
				echo -e "   mass"
				echo -e "   sw"
				;;
			mass)
				svn-mass help
				;;
			sw)
				switch -h
				;;
			*)
			$ORIGINAL $@
				;;
		esac
		;;
	mass)
		shift
		svn-mass $@
		;;
	sw)
		shift
		switch $@
		;;
	*)
		$ORIGINAL $@
		;;
esac
