How do I get the source code for moving/resizing ActiveWidgets grid?

Hi,
I think this is a great job. Is it under GPL? Where can I get the source code? I've tried at the demo site, but I need the other files you are including.
Thanks.

The sources are from ::... (for terms of use --see root links--)
http://www.brainjar.com/dhtml/drag/demo.html
for drag, ...and:
http://webfx.eae.net/ --....."-Menu- Articles - IE Specific - Generic Resize"
for resize, but someway few customized to "play" with AW.
