// Project:	XuLA2-LX25 SoC based upon the ZipCPU
//
// Purpose:	After rebuilding the same code over and over again for every
//		"scope" I tried to interact with, I thought it would be simpler
//	to try to make a more generic interface, that other things could plug
//	into.  This is that more generic interface.
