| * 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. |
