Preliminary docs are now online at the homepage :
http://www.voidspace.org.uk/python/movpy/index.html
You can download the distribution maker from :
http://www.voidspace.org.uk/cgi-bin/voidspace/downman.py?file=testenv.zip
That version is the 0.4.3 version... but with incomplete docs. As soon as the docs are complete I'll do a sourceforge release, including some prebuilt environments.
