- * Creates the OSI Fletcher checksum. See 8473-1, Appendix C, section C.3.
- * The checksum field of the passed PDU does not need to be reset to zero.
- *
- * The "Fletcher Checksum" was proposed in a paper by John G. Fletcher of
- * Lawrence Livermore Labs.  The Fletcher Checksum was proposed as an
- * alternative to cyclical redundancy checks because it provides error-
- * detection properties similar to cyclical redundancy checks but at the
- * cost of a simple summation technique.  Its characteristics were first
- * published in IEEE Transactions on Communications in January 1982.  One
- * version has been adopted by ISO for use in the class-4 transport layer
- * of the network protocol.
- *
- * This program expects:
- *    stdin:    The input file to compute a checksum for.  The input file
- *              not be longer than 256 bytes.
- *    stdout:   Copied from the input file with the Fletcher's Checksum
- *              inserted 8 bytes after the beginning of the file.
- *    stderr:   Used to print out error messages.
