Beer making tool: Qbrew

Qbrew is an open source homebrewer's recipe calculator. A pretty neat tool. I have seen a few of these recipe calculators before under freeware/shareware trials ect.
You input your recipe , select a few options like mashing ect and it tells you what's its going to be like.

Runs on Linux/BSD/Unix, Macintosh and windows. It would be a good idea for anyone who uses it to GPL (general public licence) their recipes to share with the world.

You can download it from here www.usermode.org/code.html
