# Makefile for building a monitor for the SH2-version of the PPA.
#
# This makefile supports several different versions of the monitor...
#	1. typical, stand-alone monitor 
#	2. monitor that will load into RAM and execute.
#	3. monitor that assumes it is called from the boot-block startup code.
#	   (for more information on the boot-block startup refer to the 
#		monitor webpage titled "Boot Block Safety").
#	4. the boot-block startup code.
