 4.7 Mclasserase
 ===============
 
 The `mclasserase' command is used to wipe memory cards by overwriting
 it three times: first with `0xff', then with `0x00', then with `0xff'
 again. The command uses the following syntax:
 
      `mclasserase' [`-d'] MSDOSDRIVE
 
    MS-DOS drive is optional, if none is specified, use `A:'. If more
 than one drive are specified, all but the last are ignored.
 
    `Mclasserase' accepts the following command line options:
 
 `d'
      Stop after each erase cycle, for testing purposes
 
 `p'
      Not yet implemented
 
    `Mclasserase' returns 0 on success or -1 on failure.
