 4.16 Mlabel
 ===========
 
 The 'mlabel' command adds a volume label to a disk.  Its syntax is:
      'mlabel' ['-vcsn'] ['-N' SERIAL] DRIVE:[NEW_LABEL]
 
    'Mlabel' displays the current volume label, if present.  If NEW_LABEL
 is not given, and if neither the 'c' nor the 's' options are set, it
 prompts the user for a new volume label.  To delete an existing volume
 label, press return at the prompt.
 
    The label is limited to 11 single-byte characters, e.g.
 'Name1234567'.
 
    Reasonable care is taken to create a valid MS-DOS volume label.  If
 an invalid label is specified, 'mlabel' changes the label (and displays
 the new label if the verbose mode is set).  'Mlabel' returns 0 on
 success or 1 on failure.
 
    Mlabel supports the following options:
 'c'
      Clears an existing label, without prompting the user
 's'
      Shows the existing label, without prompting the user.
 'n'
      Assigns a new (random) serial number to the disk
 'N SERIAL'
      Sets the supplied serial number.  The serial number should be
      supplied as an 8 digit hexadecimal number, without spaces
