	// What needs to be in the file:
	// - all devices, configuration for each device
	//   probably multiple lines that are adding config strings
	// - wires maybe separately, and/or as named connection points
	//   in tiles?
	// - connection pairs that can be enabled/disabled
	// - global flags and configuration registers
	// - the static data should be optional (unused conn pairs,
	//   unused devices, wires)
	//
	// - each line should be in the global namespace, line order
	//   should not matter
	// - file should be easily parsable with bison
	// - lines should typically not exceed 80 characters
	//
