-  Serving custom storages or multiple storages with the storage server
-
-    The Storage server can host multiple storages and can
-    host any kind of storage. Each storage has a unique storage
-    name.  By default, the ZEO start.py script serves a 
-    standard FileStorage with the name '1'.
-
-    You can control what storages are served by creating a Python
-    file containing definitions for the storages and using the '-S'
-    option to the start.py script to indicate the storage
-    to be served. The form of the -S option is::
-
-       -Sstorage_name=module_path:attribute_name
-
-    Where:
-
-	storage_name -- is the storage name used in the ZEO protocol.
-	   This is the name that you give as the optional
-	   'storage' keyword argument to the ClientStorage constructor.
-
-	module_path -- This is the path to a Python module
-	   that defines the storage object(s) to be served.
-	   The module path should ommit the prefix (e.g. '.py').
-
-	attribute_name -- This is the name to which the storage object
-	  is assigned in the module.
-
-
-    Consider the following example. I want to serve a FileStorage
-    in read-only mode, which I define in the module file 
-    /stores/fs.py::
-
-      import ZODB.FileStorage
-      Storage=FileStorage('/stores/fs1.fs', read_only=1)
-
-    I then start start.py with the argument::
-
-      python lib/python/ZEO/start.py -U /xxx/var/zeo.sock \
-        -S 1=/stores/fs:Storage
-
-    This option says to serve storage '1'. Storage '1' is
-    found in attribute 'Storage' from the module
-    '/stores/fs'.
-
-    Now consider a more complicated example. I want to serve the storage
-    from the previous example. I also want to serve two Oracle
-    storages that are defined in the file '/stores/oracle.py'::
-
-      import DCOracle, DCOracleStorage
-      system=DCOracleStorage.DCOracleStorage(
-        lambda : DCOracle.Connect('system/manager@spamservice')
-        )
-      scott=DCOracleStorage.DCOracleStorage(
-        lambda : DCOracle.Connect('scott/tiger@spamservice')
-        )
-
-    I simply need to include three -S options::
-
-      python lib/python/ZEO/start.py -U /xxx/var/zeo.sock \
-        -Ssystem=/stores/oracle:system                 \
-        -Sscott=/stores/oracle:scott                   \
-        -S1=/stores/fs:Storage
-
-    In this case, we made the storage and attribute name the
-    same. To connect to the 'system' or 'scott' storage, we
-    need to specify the storage in the ClientStorage constructor, as
-    in::
-
-      import ZEO.ClientStorage
-      Storage=ZEO.ClientStorage.ClientStorage(
-          '/xxx/var/zeo.sock', storage='scott')
