## DESCRIPTION

         Two files are  compared.   If  they  are  identical,  exit  status  0  is
         returned.   If  they  differ,  exit  status  1 is returned.  If the files
         cannot be opened, exit  status  2  is  returned.   If  one  of  the  file
         arguments is -, then stdin is compared to the other file.
