Grok works fine if you adjust its buildout to create a "bin/wsgi.app"
command that you can point a WSGI server at.  I did it with the
attached "buildout.cfg" section, which I was planning on putting in a
little HOWTO once the new web site was up:

[app.wsgi]
recipe = zc.recipe.egg:scripts
eggs = PolicyWebApp
entry-points = app.wsgi=sys:getrecursionlimit
initialization = import os, pwd
                 p = pwd.getpwuid(os.getuid())
                 os.environ['HOME'] = p.pw_dir  # for writable ~/.python-eggs
                 from zope.app import wsgi
                 from PolicyWebApp.wsgi import prepare
                 zapp = wsgi.getWSGIApplication('${buildout:directory}/etc/wsgi.conf')
                 def application(*args): return (prepare(*args), zapp(*args))[1]

Philipp will argue, quite rightly, that having a little WSGI script
inside of "buildout.cfg" is ugly.  And I will agree, but point out
that it's better than nothing until we have an actual recipe to
produce the WSGI script. :-)

I am using the above arrangement just fine with mod_wsgi, which allows
my app to run as a different user than Apache does (yay!).
