There is just one environment variable that needs to be set

	JROOT -- the place where the gpcp tree starts
	this is usually just C:\

The binary files of the JDK must be on the path. See the 
file SETUP.BAT for typical settings.

If you want to run J2CPS, you will need to edit the file
J2CPS.bat to reference the location of the JRE runtime
libraries.  In my case it was
	D:\jdk1.2\jre\libs

In any case, this distribution includes the symbol files
for the JDK 1.2.1 libraries. You can try these out against
the applet example in gpcp\examples\applet.  You can also
see the JHello example in gpcp\examples\hello for a simple
example that uses the Swing libraries.

Good Luck!
