+     "Zip is a compression and file packaging/archive utility. Zip is useful
+for packaging a set of files for distribution, for archiving files, and for
+saving disk space by temporarily compressing unused files or directories.
+Zip puts one or more compressed files into a single ZIP archive, along with
+information about the files (name, path, date, time of last modification,
+protection, and check information to verify file integrity). An entire
+directory structure can be packed into a ZIP archive with a single command.
+
+Zip has one compression method (deflation) and can also store files without
+compression. Zip automatically chooses the better of the two for each file.
+Compression ratios of 2:1 to 3:1 are common for text files.")
