+ * The "Fletcher Checksum" was proposed in a paper by John G. Fletcher of

+ * 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.
