 * Beginning with Family 15h Models 70h-7F, a.k.a Stoney Ridge, the PSP
 * can support an optional "combo" implementation.  If the PSP sees the
 * PSP2 cookie, it interprets the table as a roadmap to additional PSP
 * tables.  Using this, support for multiple product generations may be
 * built into one image.  If the PSP$ cookie is found, the table is a
 * normal directory table.
 *
 * Modern generations supporting the combo directories require the
 * pointer to be at offset 0x14 of the Embedded Firmware Structure,
 * regardless of the type of directory used.  The --combo-capable
 * argument enforces this placement.
 *
 * TODO: Future work may require fully implementing the PSP_COMBO feature.

/*
 * 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.
