I could never seem to remember these terminal commands, so I wrote applescripts to call them for me.  One day I said to myself, "Why not roll them into an Applescript Application?" and I answered myself "Why not indeed!"  I often have these little talks with myself.

I take no responsibility for any damage done to your computer from the use or misuse of this piece of software.

It's donation-ware, so if you feel the need to slip me a couple bucks go right on ahead.
