DM: Re: (no subject)

Consult (and consultr) are two programs that come with the c4.5 
package.
They are interactive programs used to evaulate existing trees and 
rulesets
with new cases.

The c4.5 program package was made available for a fee for purchasers 
of the
book "C4.5: Programs For Machine Learning" (1993) by Ross Quinlan.
According to the notice in the book the programs are copyrighted and 
may not
be freely distributed.

I think the book is currently out of print and the publisher, Morgan
Kaufmann, no longer sells the software.  I don't know what the status 
of the
software is currently.
