# Filename:	Makefile
#
# Project:	Zip CPU -- a small, lightweight, RISC CPU soft core
#
# Purpose:	This makefile builds an assembler preprocessor (zpp), an
#		assembler (zasm) and a disassembler (zdump).  Make with no
#		arguments will produce these files.  Other targets include:
#
#	make clean
#	make test
#		Assembles a test file and then produces a disassembly of it.
#	make depends
#		Doesn't work.  Dependencies are currently all hand coded.
#	make tags
#	make install
#		Attempts to copy zasm, zpp and zdump to the install directory, 
#		defined herein
