+ * 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.
