// Project:     Zip CPU -- a small, lightweight, RISC CPU soft core

//

// Purpose:     A bench simulator for the CPU.  Eventually, you should be
8
//              able to give this program the name of a piece of compiled
9
//              code to load into memory.  For now, we hand assemble with the
10
//              computers help.
