-Zope Enterprise Objects, ZEO 0.2
+Zope Enterprise Objects
-  Put this package (the ZEO directory, without any wrapping directory
-  included in a distribution) in your Zope lib/python.
-  Note -- This release of ZEO requires Zope 2.2.2 or a CVS checkout
-    of Zope. See 'CHANGES.txt' for details.
-  You also need to symbolically link (or copy) ZServer to lib/python::
-    cd lib/python
-    ln -s ../../ZServer .
-  Finally, you need to link the cPickle extension from your lib/python
-  directory into your ZEO directory::
-    cd lib/python/ZEO
-    ln -s ../cPickle.so .
-  This is necessary because ZEO uses a (relatively) new
-  cPickle feature that wasn't included in Python 1.5.2.
-  Starting (and configuring) the ZEO Server
-    To start the storage server, go to your Zope install directory and::
-      python lib/python/ZEO/start.py -p port_number
-    (Run start without arguments to see options.)
-    Of course, the server and the client don't have to be on the same
-    machine.
-    If the server and client *are* on the same machine, then you can use 
-    a Unix domain socket::
-      python lib/python/ZEO/start.py -U filename
-    The start script provides a number of options not documented here.
-    See doc/start.txt for more information.
-  Running Zope as a ZEO client
-    To get Zope to use the server, create a custom_zodb module,
-    custom_zodb.py, in your Zope install directory, so that Zope uses a
-    ClientStorage::
-      import ZEO.ClientStorage
-      Storage=ZEO.ClientStorage.ClientStorage(('',port_number))
-    (See the misc/custom_zodb.py for an example.)
-    You can specify a host name (rather than '') if you want.  The port
-    number is, of course, the port number used to start the storage
-    server.
-    You can also give the name of a Unix domain socket file::
-      import ZEO.ClientStorage
-      Storage=ZEO.ClientStorage.ClientStorage(filename)
-    There are a number of configuration options available for the
-    ClientStorage. See doc/ClientStorage.txt for details.
-    If you want a persistent client cache which retains cache contents
-    across ClientStorage restarts, you need to define the environment
-    variable, ZEO_CLIENT, to a unique name for the client.  This is
-    needed so that unique cache name files can be computed.  Otherwise,
-    the client cache is stored in temporary files which are removed when
-    the ClientStorage shuts down.  For example, to start two Zope
-    processes with unique caches, use something like:
-      python z2.py -P8700 ZEO_CLIENT=8700
-      python z2.py -P8800 ZEO_CLIENT=8800
-  Zope product installation
-    Normally, Zope updates the Zope database during startup to reflect
-    product changes or new products found. It makes no sense for
-    multiple ZEO clients to do the same installation. Further, if
-    different clients have different software installed, the correct
-    state of the database is ambiguous.
-    Starting in Zope 2.2, Zope will not modify the Zope database
-    during product installation if the environment variable ZEO_CLIENT
-    is set. 
-    Normally, Zope ZEO clients should be run with ZEO_CLIENT set so
-    that product initialization is not performed.
-    If you do install new Zope products, then you need to take a
-    special step to cause the new products to be properly registered
-    in the database.  The easiest way to do this is to start Zope
-    once without ZEO_CLIENT set.
-    The interaction between ZEO and Zope product installation is
-    unfortunate.  In the future, this interaction will be removed by 
-  Notes for non Zope users
-    First, we regret the amount of dependence on Zope. We intend for
-    the dependence to decrease in the long run.
-    Known dependencies:
-      - The Zope lib/python/Shared directory must be in the Python
-        path. This is due to a lame dependency on some Zope XML
-        facilities used by ZODB for XML export and import.
-      - ZServer should be in the Python path, or you should copy the
-        version of asyncore.py from ZServer (from Zope 2.2 or CVS) to
-        your Python path, or you should copy a version of a asyncore
-        from the medusa CVS tree to your Python path. A recent change
-        in asyncore is required.
-      - The module, ThreadedAsync must be in the python path.
-      - The version of cPickle from Zope, or from the python.org CVS
-        tree must be used. It has a hook to provide control over which
-        "global objects" (e.g. classes) may be pickled.
