// 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.
