INSTALLATION
--------------------------------------------
To build JIGSAW 
cd into the 'src/main' 
xmkmf -a
make install

This will place the application binary (jigsaw) in the
bin/$(HOSTYPE) directory where $(HOSTTYPE) should already be defined
on your system to refer to your os (e.g. Linux, SunOS, etc..)  
if HOSTTYPE is not defined, the binary will be placed directly in the bin/ directory.

To build the oc1 decision tree software, cd into 'lib/oc1' and follow the instructions in the README (or just type 'make')
this should compile the "mktree" binary, place this binary file somewhere in your path.
