- * 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.
