                     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
                     17: of the normally mounted file systems
                     18: is performed.
                     19: Output includes the number of files on the file system,
                     20: the number of these that are 'large', the number
                     21: of indirect blocks,
                     22: the number
                     23: of used blocks, and the number of free blocks.
                     24: .sp
                     25: check_____ works by examining the i-nodes
                     26: on the file system and is entirely
                     27: independent of its directory hierarchy.
                     28: The file system may be,
                     29: but need not be, mounted.

                     41: blocks missing, duplicated, and bad block addresses.
                     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.
