Once you've retrieved the distribution, create a directory in which the Harvest software will live (typically /usr/local/harvest), then change your current directory to it. To unpack the binary distribution, run the following command to extract the software into the current directory:
% gzip -dc harvest-CPU-MACHINE-OS.tar.gz | tar xf -
WARNING: You must extract the Harvest software in an empty directory; do not extract it over any older version of Harvest. Finally, define the HARVEST_HOME environment variable. HARVEST_HOME is the Harvest directory where you extracted the distribution into.
% cd harvest-1.4
% setenv HARVEST_HOME `pwd`
