Subject: Suspend 2 merge: 47/51: GZIP support.
Date: Thu, 25 Nov 2004 00:02:19 +1100 [thread overview]
Message-ID: <1101300182.5805.383.camel@desktop.cunninghams> (raw)
In-Reply-To: <1101292194.5805.180.camel@desktop.cunninghams>
The original compressor. Slow. I've tried to drop it, but for reasons I
simply don't understand, some users still want it.
