Some of the files in the rover engineering data set are compressed
using Zip format.  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.

Files in the SOFTWARE directory contain a description of the Zip file
format and also the complete source code for the UNZIP utility.  You
can also find pre-built binaries for most platforms on-line at
