DDEESSCCRRIIPPTTIIOONN
       Print or check SHA1 (160-bit) checksums.  With no FILE,
       or when FILE is -, read standard input.

       --bb, ----bbiinnaarryy
              read in binary mode

       --cc, ----cchheecckk
              read SHA1 sums from the FILEs and check them

       --tt, ----tteexxtt
              read in text mode (default)

              don't output anything, status code shows success

       --ww, ----wwaarrnn
              warn about improperly formatted checksum lines

       ----hheellpp display this help and exit

       ----vveerrssiioonn
              output version information and exit

       The sums are computed as described in FIPS-180-1.
       When  checking,  the input  should  be a former output
       of this program.  The default mode is to print a line
       with checksum, a character  indicating  type  (`*'
       for binary, ` ' for text), and name for each FILE.
