module to allow automatically compressed CGI output

 CGI::Compress::Gzip extends the CGI module to auto-detect whether the client
 browser wants compressed output and, if so and if the script chooses HTML
 output, apply gzip compression on any content header for STDOUT.
 CGI::Compress::Gzip is intended to be a drop-in replacement for CGI.pm.
 .
 Apache mod_perl users may wish to consider the Apache::Compress or
 Apache::GzipChain modules, which allow more transparent output compression
 than this module can provide. However, as of this writing those modules are
 more aggressive about compressing, regardless of Content-Type.
