   30    * The Java SQL framework allows for multiple database drivers. Each driver
   31    * should supply a class that implements the Driver interface
   32    * 
   33    * <p>
   34    * The DriverManager will try to load as many drivers as it can find and then
   35    * for any given connection request, it will ask each driver in turn to try to
   36    * connect to the target URL.
   37    * 
   38    * <p>
   39    * It is strongly recommended that each Driver class should be small and
   40    * standalone so that the Driver class can be loaded and queried without
   41    * bringing in vast quantities of supporting code.
   42    * 
   43    * <p>
   44    * When a Driver class is loaded, it should create an instance of itself and
   45    * register it with the DriverManager. This means that a user can load and
   46    * register a driver by doing Class.forName("foo.bah.Driver")
   47    *
