Freeware for tiling windows Possible Duplicate:
  What Window Management Options exist for OS X?  




I've seen many, many utilities for resizing windows (BST, Moom, Divvy, SizeUp...) but I wanted to know if there were any available for free. Most of these utilities have a free trial, but I'd expect there's at least one available completely free.

So, is there one?
BetterTouchTool is a freeware application mainly for defining custom gestures of trackpads and Magic Mice, but it also has the ability to tile windows.
