     "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.")
