       package require Tcl 8.2

       package require cksum ?1.0?

       ::crc::cksum ?-format format? message

       ::crc::cksum ?-format format? -filename file

DESCRIPTION

       This  package  provides a Tcl-only implementation of the cksum(1) algorithm based upon information provided at in the GNU implementation of
       this program as part of the GNU Textutils 2.0 package.

COMMANDS

       ::crc::cksum ?-format format? message

       ::crc::cksum ?-format format? -filename file
	      The command takes string data or a file name and returns a checksum value calculated using the cksum(1)  algorithm.  The	result	is
	      formatted using the format(n) specifier provided or as an unsigned integer (%u) by default.
