// Name: tzload.c
// Created: May 2020
// Author(s): Philip Smart
// Description: A TranZPUter helper program, responsible for loading images off the SD card into
// memory on the tranZPUter board or host mainboard./
// Credits:
// Copyright: (c) 2019-2021 Philip Smart <philip.smart@net2net.org>
//
// History: May 2020 - Initial write of the TranZPUter software.
// Feb 2021 - Replaced getopt_long with optparse as it is buggy and crashes.
//
// Notes: See Makefile to enable/disable conditional components
