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 which is available on SQLA ``Engine``
and ``Pool`` objects corresponds to a logger specific to that 
instance only.

E.g.::

    engine.echo = True

is equivalent to::

    import logging
    logger = logging.getLogger('sqlalchemy.engine.Engine.%s' % hex(id(engine)))
    logger.setLevel(logging.DEBUG)

    This has the effect of setting the Python logging level for the namespace
    of this element's class and object reference.  A value of boolean ``True``
    indicates that the loglevel ``logging.INFO`` will be set for the logger,
    whereas the string value ``debug`` will set the loglevel to
    ``logging.DEBUG``.
