+"""Logging control and utilities.
+
+Control of logging for SA can be performed from the regular python logging
+module.  The regular dotted module namespace is used, starting at
+'sqlalchemy'.  For class-level logging, the class name is appended.
+
+The "echo" keyword parameter, available on SQLA :class:`_engine.Engine`
+and :class:`_pool.Pool` objects, corresponds to a logger specific to that
+instance only.
