SYNOPSIS
       package require Tcl  8.2

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

DESCRIPTION
       This  package  provides a Tcl-only implementation of the cksum(1) algo-
       rithm 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.

OPTIONS
       -filename name
              Return a checksum for the file contents instead of for parameter
              data.

       -format string
              Return the checksum using an alternative format template.

EXAMPLES
       % crc::cksum "Hello, World!"
       2609532967

       % crc::cksum -format 0x%X "Hello, World!"
       0x9B8A5027

       % crc::cksum -file cksum.tcl
