[plt-scheme] gerbils; or invasion of the killer rodents

This is an announcement of the first "official" release of gerbil.
Gerbil is a distributed dialect of scheme implemented as a plt macro
language. As such it inherits all the traits of plt-scheme and provides
abstractions and libraries for actor-oriented distributed programming.

Gerbil was presented in the February 23 Bost-Lisp Meeting. Comparing to
the prerelease code from then, this snapshot adds support for TCP
and virtual network simulation, integrates additional useful
functionality and cleans up some.

You can get gerbil here:
http://web.media.mit.edu/~vyzo/gerbil
http://web.media.mit.edu/~vyzo/gerbil/gerbil-20090427.tar.gz

For the time being, gerbil has to be installed as a collection. Sorry,
no planet package yet.

Documentation:
There is a schemer's guide here:
http://web.media.mit.edu/~vyzo/gerbil/guide.org.txt

The guide is still in progress, but it includes a fairly comprehensive
tutorial. It is best to treat it as an org-mode file and read it in
emacs, as I haven't yet rendered it with scribble.

Happy hacking!
