Software of this data set is provided in form of zipped files in the
SOFTWARE directory.
They are all indicated by the extension ".ZIP". ZIP is a utility that
compresses files and also allows for multiple files to be stored in a
single Zip archive. You will need the UNZIP utility to extract the
files.

It is far simpler to obtain a pre-built binary of the UNZIP application
for your platform. Binaries for most pla tforms are available from the
Info-ZIP web site, currently at these URLs:
