It's really easy.
To convert a Zope instance to a combination Zope/Zeo instance
on *nix:

0) shut down Zope.

1) Where your zope software is installed, run this:
   ./bin/mkzeoinstance.py /path/to/your/instance 8100

   That gives you etc/zeo.conf
   as well as bin/runzeo and bin/zeoctl.
   No need to edit anything in these.

2) edit etc/zope.conf:

	Uncomment the very last section, under the
	comment heading # ZEO Client Storage.

	Comment out the Filestorage section above that,
	which begins with <zodb_db main>
	and ends with </zodb_db>.


3) In your instance home, start ZEO first, then zope:

   ./bin/zeoctl start
   ./bin/zopectl start

You're done.

I don't know where Debian puts zope-related stuff,
so if you're using their Zope packages you may have 
to use find or locate to figure out what's where.
