Netlogo not packaged for Squeeze?

Netlogo doesn't seem to be packaged for squeeze. I find this strange because Netlogo has been around for a while, is widely used, and is licenced under the GPL. Details, see  page,http://en.wikipedia.org/wiki/NetLogo
and the source is available from https://github.com/NetLogo/NetLogo

What's the best way to proceed? Is there an "unofficial" package somewhere? Is it planned to be in Wheezy?
