I'll go you one better Max: a combined bat/perl script that downloads and
installs a snapshot.  Attached is what I use to install the latest snapshots;
put it anywhere (rename it to ".bat", I had to get it through Outlook), MAKE
SURE YOU DON'T HAVE ANY CYGWIN THINGS RUNNING, run it, and you're set.  Only
tried on XP.  Needs perl and wget in your Windows PATH.

USE AT YOUR OWN RISK.  THERE'S NO "UNDO".  NOT SUPPORTED BY ME OR ANYBODY ELSE
IN ANY WAY.  THIS MEANS YOU.
