Scatterand is still in development, and a download package is not yet available. You can get the source code using Bazaar with the following command:
bzr branch lp:scatterand/trunk
You can browse the source code at https://code.launchpad.net/scatterand.
Scatterand is in active development and is functional in a test environment (Python 2.6 with its built-in web server), but is not ready for everyday use. Current versions of Scatterand should not be installed on production servers.
