[Motmot] Conversion of avi to fmf

[Kristin Branson]

A new version of Mtrax, now called Ctrax (The Caltech Multiple Fly
Tracker), is now available for download.

The Ubuntu Hardy deb file is available from Andrew Straw's repository:
http://debs.astraw.com/hardy/.

All versions are available from our new distribution site:
http://developer.berlios.de/projects/ctrax

I'm working on writing up documentation and making our Matlab behavior
analysis routines available as well.

Thanks for your interest,
Kristin Branson
