The proposal for Zope 2 is InstallationAndConfiguration.  In Zope
2, it'll create instances, start/stop standalones, start/stop ZEO
clients and servers.  I imagine it will do much the same in Zope
3, though it can certainly do more or less.

The package is the meeting point for the script and the Zope software
that it's controlling.  The script has just enough smarts to locate
the directory where the software (packages) is stored and imports
the control package to actually implement the commands.  That way,
the script is essentially future-proof, and different Zope software
versions can implement the commands, or add new commands, in their
own way.

You can see about half of this code in the Zope module, on the
zigg_unix-install-control-config-branch.  Keep in mind it's about
50% done; I'm mostly using the CVS branch to shuffle it between
UNIX systems to test compatibility.

(Incidentally, rdmurray gave his +1 for Zope.App.Control on IRC.)
