This directory contains the modified source files required to extend
C4.5 release 6 to incorporate the postprocessing described in:

  Geoffrey I Webb, Further Experimental Evidence against the Utility of
  Occam's Razor, Journal of Artifical Intelligence Research, 4.


To compile this system:

1)  Replace the the following C4.5 release 6 source files with those
    found in this directory:
	Makefile
	besttree.c
	c4.5.c
	extern.i

2)  Add the following file to the source directory:
	postprocess.c

3)  Make C4.5 as usual.


To invoke postprocessing, run the system as normal with the additional
argument -P.
