+ *	@(#)dname.c	1.3 - 95/07/31
+ *	
+ *
+ * RTEMS monitor driver names support.
+ *
+ * There are 2 "driver" things the monitor knows about.
+ *
+ *    1. Regular RTEMS drivers.
+ *         This is a table indexed by major device number and
+ *         containing driver entry points only.
+ *
+ *    2. Driver name table.
+ *         A separate table of names for drivers.
+ *         The table converts driver names to a major number
+ *         as index into the driver table and a minor number
+ *         for an argument to driver.
+ *
+ *  Drivers are displayed with 'driver' command.
+ *  Names are displayed with 'dname' command.
+ *
+ *  $Id$
