Uninstalling older versions of Octave on a Mac

[Samuel H. Dupree, Jr.]

I'm running several versions of Octave running on my Mac G4 (running Mac 
OS X version 10.4.11): 2.1.73, 2.9.9 and 2.9.17. I would like to 
uninstall 2.1.73 and 2.9.9 cleanly and completely. Does anyone have a 
script to do this?

Thanks in advance.

Sam Dupree.
