# Filename:     Makefile
#
# Project:      Zip CPU -- a small, lightweight, RISC CPU soft core
#
# Purpose:      This makefile builds the final verilator simulation of the
#               zipsystem.  Specifically, it builds the final C++ portion
#       of the simulator, and thus the final simulator executable.
#
#       This simulator depends upon the libelf library.
