        !             4: .sh SYNOPSIS
        !             5: .bd /etc/mkfs

        !             8: .sh DESCRIPTION
        !             9: .it Mkfs
        !            10: constructs a file system
        !            11: by writing on the special file
        !            12: .it special
        !            13: according to the directions
        !            14: found in
        !            15: the prototype file
        !            16: .it proto.
        !            17: The prototype file
        !            18: contains tokens separated by spaces or
        !            19: new lines.
        !            20: The first token is the name of a file
        !            21: to be copied onto block zero as
        !            22: the bootstrap program
        !            23: (see boot procedures(VIII)).
        !            24: The second token is a number specifying the
        !            25: size of the created file system.
        !            26: Typically it will be the number of blocks on the device,
        !            27: perhaps diminished
        !            28: by space for swapping.
        !            29: The next token is the i-list size in blocks
        !            30: (remember there are 16 i-nodes per block).
        !            31: The next set of tokens comprise the specification
        !            32: for the root file.
        !            33: File specifications consist of tokens
        !            34: giving the mode,
        !            35: the user-id,
        !            36: the group id,
        !            37: and the initial contents of the file.
        !            38: The syntax of the contents field
        !            39: depends on the mode.
        !            40: .s3
        !            41: The mode token for a file is a 6 character string.
        !            42: The first character
        !            43: specifies the type of the file.
        !            44: (The characters
        !            45: .bd \*-bcd
        !            46: specify regular, block special,
        !            47: character special and directory files
        !            48: respectively.)
        !            49: The second character of the type
        !            50: is either
        !            51: .bd u
        !            52: or
        !            53: .bd \*-
        !            54: to specify set-user-id mode or not.
        !            55: The third is
        !            56: .bd g
        !            57: or
        !            58: .bd \*-
        !            59: for the set-group-id mode.
        !            60: The rest of the mode
        !            61: is a three digit octal number giving the
        !            62: owner, group, and foreigner read, write, execute
        !            63: permissions (see
        !            64: .it chmod
        !            65: (I)).
        !            66: .s3
        !            67: Two decimal number
        !            68: tokens come after the mode; they specify the
        !            69: user and group ID's of the owner of the file.
        !            70: .s3
        !            71: If the file is a regular file,
        !            72: the next token is a pathname
        !            73: whence the contents and size are copied.
        !            74: .s3
        !            75: If the file is a block or character special file,
        !            76: two decimal number tokens
        !            77: follow which give the major and minor device numbers.
        !            78: .s3
        !            79: If the file is a directory,
        !            80: .it mkfs
        !            81: makes the entries \fB.\fR and \fB..\fR
        !            82: and then
        !            83: reads a list of names and
        !            84: (recursively)
        !            85: file specifications for the entries
        !            86: in the directory.
        !            87: The scan is terminated with the
        !            88: token \fB$\fR.
        !            89: .s3
        !            90: If the prototype file cannot be opened and
        !            91: its name consists of a string of digits,
        !            92: .it mkfs
        !            93: builds a file system with a single
        !            94: empty directory on it.
        !            95: The size of the file system is the value
        !            96: of
        !            97: .it proto
        !            98: interpreted as a decimal number.
        !            99: The i-list size is the file system size
        !           100: divided by 50.
        !           101: (This corresponds to an average size of
        !           102: three blocks per file.)
        !           103: The boot program is left uninitialized.
        !           104: .s3
        !           105: A sample prototype specification follows:
