     DESCRIPTION
          The following commands will return a true value (exit code
          of 0) if you are on a processor that the command name
          indicates.

               pdp11   True if you are on a PDP-11/45 or PDP-11/70.

               u3b     True if you are on a 3B20 computer.

               u3b2    True if you are on a 3B2 computer.

               u3b5    True if you are on a 3B5 computer.

               vax     True if you are on a VAX-11/750 or VAX-11/780.

               4d60    True if you are on a MIPS computer.

               m68000  True if you are on a 68000.

          The commands that do not apply will return a false (non-
          zero) value.  These commands are often used within makefiles
          (see make(1)) and shell procedures (see sh(1)) to increase
          portability.
