Some HTTP servers serve gzipped documents. Lynx is designed to decompress them
by invoking gzip -d tempfile.gz. For some sites, however, this is unacceptable
because gzip may be banned for political reasons. This utility provides the
functionality equivalent to gunzip (or gzip -d) using zlib. (Since zlib's name
doesn't start with 'g' it doesn't fall under the same political ban as gzip.)
