+Using ZConfig to configure Before storages
+==========================================
+
+To use before storages from ZConfig configuration files, you need to
+import zc.beforestorage and then use a before storage section.
+
+    >>> import ZODB.config
+    >>> storage = ZODB.config.storageFromString("""
+    ...
+    ... %import zc.beforestorage
+    ...
+    ... <before>
+    ...     before 2008-01-21
+    ...     <filestorage>
+    ...         path Data.fs
+    ...     </filestorage>
+    ... </before>
+    ... """)
+
+    >>> storage
+    <Before: Data.fs before 2008-01-21 00:00:00.000000>
+
+    >>> storage.close()
+
+If we leave off the before option, we'll use the current time:
+
+    >>> storage = ZODB.config.storageFromString("""
+    ...
+    ... %import zc.beforestorage
+    ...
+    ... <before>
+    ...     <filestorage>
+    ...         path Data.fs
+    ...     </filestorage>
+    ... </before>
+    ... """)
+
+    >>> storage
+    <Before: Data.fs before 2008-01-21 18:22:48.000000>
