SYNOPSIS
	  use CGI::Compress::Gzip;

	  my $cgi = new	CGI::Compress::Gzip;
	  print	$cgi->header();
	  print	"<html>	...";

DESCRIPTION
       This is intended	for internal use only!	Use CGI::Compress::Gzip
       instead.

       This CGI::Compress::Gzip	helper class subclasses	IO::Zlib.  It is is
       needed to make sure that	output is not compressed until the CGI header
       is emitted.  This filehandle delays the ignition	of the zlib filter
       until it	sees the exact same header generated by
       CGI::Compress::Gzip::header() pass through it's WRITE() method.	If you
       change the header before	printing it, this class	will throw an
       exception.

       This class holds	one global variable representing the previous default
       filehandle used before the gzip filter is put in	place.	This
       filehandle, usually STDOUT, is replaced after the gzip stream finishes
       (which is usually when the CGI object goes out of scope and is
       destroyed).

FUNCTIONS
       OPEN
	   Overrides IO::Zlib::OPEN.  This method doesn't actually do anything
	   -- it just stores it's arguments for	a later	call to	SUPER::OPEN in
	   WRITE().  The reason	is that	we may not have	seen the header	yet,
	   so we don't yet know	whether	to compress output.

       WRITE buffer, length, offset
	   Emit	the uncompressed header	followed by the	compressed body.

       CLOSE
	   Flush the compressed	output.
