-"""OpenStack logging handler.
-
-This module adds to logging functionality by adding the option to specify
-a context object when calling the various log methods.  If the context object
-is not specified, default formatting is used. Additionally, an instance uuid
-may be passed as part of the log message, which is intended to make it easier
-for admins to find messages related to a specific instance.
-
-It also allows setting of formatting information through conf.
