+#
+# 12/22/2011 1.3 wbw - removed all built-in config stuff, operation is now entirely
+#                      dependent on variables CONFIG, ROMSIZE, and CPU
+#
+# 12/02/2011 1.3 wbw - replaced makever functionality with built-in makefile stuff
+#
+# 11/29/2011 1.3 dwg - uses makever to generate stdincl.inc from the version.hpp file
+#
+# 11/19/2011 1.3 dwg - added n8vem_vdu to "usage" and "all" rules
+#                      enhanced clean to get files in $(OUTDIR)
+#                      added custom to "all" rule
+
+#
+# The operation of this makefile is entirely dependent on the setting
+# of three variables: CONFIG, ROMSIZE, and CPU:
+#
+# CONFIG determines which configuration to build which means that
+# it will determine the config_xxx.asm config settings file to
+# include as well as the output file names.  So, for example,
+# if CONFIG is "n8vem", the config_n8vem.asm file will be used
+# for BIOS configuration settings and the output files will be
+# n8vem.rom, n8vem.sys, and n8vem.com.
+#
+# ROMSIZE specifies the size of the ROM image to be produced and
+# currently must be either "1024" for a 1MB ROM or "512" for a
+# 512KB ROM.
+#
+# CPU specifies the instruction set to be used in assembly and
+# must be either "80" for Z80 or "180" for Z180.  Currently,
+# you should use 180 for N8 ROMs and 80 for everything else.
+#
+# SYS specifies the system variant to build in.  CPM will
+# build traditional CP/M.  ZSYS will build ZSystem which
+# currently means ZSDOS 1.2 & ZCPR 1.0
+#
+# ROMNAME names the output file.  It defaults to
+# CONFIG.  The output of the build will be:
+# <ROMNAME>.rom, <ROMNAME>.sys, and <ROMNAME>.com.
+#
+# These variables can be passed into the makefile by the command
+# line, hardcoded in this file, or set as environment variables
+# in the OS.  To use a command line, use the following format:
+#
+#   make CONFIG=<config> ROMSIZE=<romsize> CPU=<cpu> SYS=<sys> ROMNAME=<romname>
+#
+# An example of this is:
+#
+#   make CONFIG=n8vem ROMSIZE=512 CPU=80 SYS=CPM ROMNAME=n8vem
+#
+# Alternatively, you can specify the variables by hardcoding them
+# in this file.  To do so, uncomment the five lines after these
+# comments and change the values as desired.
+# If the variables are specified this way, you would then invoke
+# the make by simply using "make"
+#
+# If you want to set them as environment variables, you can
+# do this with commands like the following at an OS command
+# prompt or in a batch file:
+#
+#   SET CONFIG=n8vem
+#   SET ROMSIZE=512
+#   SET CPU=80
+#   SET SYS=CPM
+#   SET ROMNAME=n8vem
+#
+# Note: use "make clean" to delete temporary and output files
+#
+# A good idea is to do a clean with every build and this can be
+# accomplished on one command line doing something like this:
+#
+#   make clean all CONFIG=n8vem ROMSIZE=512 CPU=80 SYS=CPM ROMNAME=n8vem
+#
+# or, if you are using hard coded variables above:
+#
+#   make clean all
+#
+# Uncomment and update values below to hardcode settings:
+#
+#CONFIG := n8vem
+#ROMSIZE := 512
+#CPU := 80
+#SYS := CPM
+#ROMNAME := n8vem
