        !            11: will examine a file system,
        !            12: build a bit map of used blocks,
        !            13: and compare this bit map against
        !            14: the bit map maintained on the file system.
        !            15: If the file system is not specified,
        !            16: a check of all

        !            21: of indirect blocks,
        !            22: the number
        !            23: of used blocks, and the number of free blocks.

        !            25: check_____ works by examining the i-nodes

        !            42: Diagnostics are also produced for block numbers passed as parameters.
        !            43: In each case, the block number, i-number, and
        !            44: block class (i_ = inode, x_ indirect, f_ free) is printed.
