56	<p>
57	Each driver should supply a service that implements
58	the Driver interface.
59

61	<p>The DriverManager will try to load as many drivers as it can
62	find, and then for any given connection request, it will ask each
63	driver in turn to try to connect to the target URL.
64
65	</p>
66	<p>
67	It is strongly recommended that each Driver object should be
68	small and standalone so that the Driver object can be loaded and
69	queried without bringing in vast quantities of supporting code.
