       This  manual  page  documents  the  GNU  version of cckkssuumm.
       cckkssuumm computes a cyclic redundancy check  (CRC)  for  each
       named  file,  or  the  standard input if none are given or
       when a file named `-' is given.  It  prints  the  CRC  for
       each  file along with the number of bytes in the file, and
       the file name unless no arguments were given.

       cckkssuumm is typically used to make sure that files have  been
       transferred by unreliable means (such as netnews) have not
       been corrupted, by comparing  the  cckkssuumm  output  for  the
       received  files  with  the  cckkssuumm  output for the original
       files.  The CRC algorithm  is  specified  by  the  POSIX.2
       standard.   It  is not compatible with the BSD or System V
       ssuumm programs; it is more robust.

       _-_-_h_e_l_p Print a usage message and exit with a non-zero sta-
              tus.

       _-_-_v_e_r_s_i_o_n
              Print  version  information on standard output then
              exit.
