Okay, well I guess that's what you get when you have your wisdom teeth
pulled out and have to miss a meeting.  Anyway, it gave me a chance to
learn a bit about how web servers work....

Here are the steps I followed.  Everything seems to be working, but
since this is my first time playing with apache, php, htdig, etc, I
would appreciate someone (probably Pete Ross if you have time)
checking that I haven't left anything out or done something stupid.
Also, if anyone wants to test these pages, point your browser to
`http://venus.cs.mu.oz.au/'.

The last step, which I haven't done yet, will be to change the DNS
entry for www.mercury.cs.mu.oz.au to point to venus instead of hydra.

Steps for moving Mercury WWW site to a new machine:

	- make sure the following packages are installed (Debian
	  package names used here): apache, hypermail, php3, php3-cgi,
	  htdig.

	- make sure /etc/apache/srm.conf contains the following two
	  lines:
		DocumentRoot /var/www
		Alias /doc/ /usr/share/doc/

	- ln -s /home/mercury5/installed_w3 /var/www

	- ln -s /home/mercury5/installed_w3/htdig/htdig-mercury.conf /etc/htdig/
	
	- copy contents of /var/spool/htdig/ to the new machine

	- edit w3/bin/install_webpages (from CVS repository) and
	  change the machine-name check to the new machine

	- edit w3/include/search.inc and make sure the search action
	  is pointing to the new machine

	-  edit and install new crontabs for new and old machines for
	   user `mercury'

Here are the relevant changes to the CVS repository:


Estimated hours taken: 4 (mostly trying to work out what needed to be done)

Move the web server functionality from hydra to venus.
