 For applications that require data compression, the functions in this
 module allow compression and decompression, using the zlib library,
 which is based on GNU zip.  The zlib library has its own home page at
-\code{http://www.cdrom.com/pub/infozip/zlib/}.

 Version 1.0.4 is the most recent version as of December, 1997; use a
 later version if one is available.
