+This module is a thin wrapper around librbd.
+
+It currently provides all the synchronous methods of librbd that do
+not use callbacks.
+
+Error codes from librbd are turned into exceptions that subclass
+:class:`Error`. Almost all methods may raise :class:`Error`
+(the base class of all rbd exceptions), :class:`PermissionError`
+and :class:`IOError`, in addition to those documented for the
+method.
