 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.
