First, begin by getting the gzipped tar
ball containing all the source code you will need to begin. Do
not worry: virtually all popular decompression programs can expand the
contents of this file (tar, WinZip, etc.).
From this point on, we will assume that you have extracted the files
to the directory "/tutorial". In POSIX-compliant systems, the command
sequence is
% cd /
% tar xvfz ~/tutorial.tar.gz
Using WinZip, simply extract the files to a folder called
"tutorial" off of your hard drive.
In all systems, Java needs to know where all the files are
located. You can tell it this by setting the CLASSPATH environment
variable as follows:
% setenv CLASSPATH .:/tutorial
