Before you learn more about what the Luggage can do, you should know that it is a command line tool. If you are not comfortable with the command line or the Terminal in Mac OS X, that really is a prerequisite. This series of posts cannot teach you that, but I will try to fully outline each command and text file used so you can follow along.
You should additionally have a grasp of at least the basics of UNIX shells and shell scripting in order to use the Luggage.
