This is one of the must app for rooted devices. Developer put this on sale for Limited time (unknown from the market description) and half of this sale revenue goes to cancer society. This donation itself should be enough to buy this.
This application got plenty of features, in short:
Like titanium backup, can do all low level backup/email apk to friends
Can install Custom ROMs
Another cool feature is, all system icons can be edited in this app itself (Like battery icon change)
CPU tweaks
Many other functions

Do we get a receipt stating that it will go to the Cancer Society so that I can claim back as a tax offset?
nah I'm kidding ;)
