-This tree now contains makefiles and tools to build on Linux and 
-macOS. Linux is rather more thoroughly tested compared to macOS.
-
-To get here, TASM and the propeller generation tools needed to be 
-replaced, and since the unix filesystem is usually case-sensitive, 
-and CP/M and windows are not, the cpm tools were made case-insensitive.
-
-TASM was replaced with uz80as, which implements a subset of TASM and 
-fixes some bugs.  However, I needed to add some functionality to make 
-it build the sources as they exist in this tree.   In particular, one 
-thing to be very careful of is that TASM is not entirely consistent 
-with respect to the .DS directive. it's usually a bad idea to mix 
-.DS, .FILL, .DB with .ORG.
-
-	.DS n is best thought of as .ORG $ + n
-	.ORG  changes the memory pointer, but does not change the file
-	      output point.  It works a lot more like M80, SLR* .PHASE
-
-It assumes that you have some standard system tools and libraries 
-installed, specifically: gcc, gnu make, libncurses, and srecord.
-Typically, something like this will take care of adding all
-required packages in Linux:
-
-	sudo apt install build-essential libncurses-dev srecord
-
-For MacOS, you will need:
-
-	brew install srecord
-
-To build:
-	cd to the top directory and type "make".
-
-By default, this will generate all of the standard configurations of
-RomWBW for all platforms.  If you just want to build the ROM for a
-specific platform and configuration you can use
-
-	make ROM_PLATFORM=<platform> ROM_CONFIG=<config>
-
-where <platform> is one of the supported platforms such as SBC, RCZ80, 
-etc. and <config> is a configuration of that platform.  For example,
-to build the "126" configuration of the "SCZ180" platform:
-
-	make ROM_PLATFORM=SCZ180 ROM_CONFIG=126
-
-Please be aware that the make-based build does have a few deficiencies.
-
-First and most important, the Makefiles do not handle reruns very well.
-To ensure a full buld, use "make clean" from the top level directory
-before running the actual build.
-
-Second, there are some build failures that will not stop the make 
-process.  Most of this is because real CP/M 2.2 tools are used in 
-places and CP/M 2.2 does not allow programs to return a result code.
-
-Third, not all dependencies are properly handled.  So, changes to some
-files will not cause things to rebuild as appropriate.  In general, I
-recommend doing a "make clean" before running "make" to ensure that
-everything is fully rebuilt.
-
-For macOS users, you may encounter a failure reading or writing files.
-This is caused by protection features in macOS (at least, in Catalina)
-that prevent programs built on your local system (unsigned) from
-running.  To disable this feature:
-
-1) Make sure you exit System Preferences.
-2) Open a terminal session and type the following.  You will need to
-   authenticate with an admin account.  sudo spctl --master-disable
-3) Exit terminal
-4) Go into System Preferences and choose Security and Privacy
-5) Select the General tab if it isn't already selected
-6) You should now see a third selection under
-   "Allow apps downloaded from:" of Anywhere - select this.
-7) Now you can run the build successfully.
-
-DISCLAIMER: You do this at your own risk.  I highly recommend that you
-return the settings back to normal immediately after doing a build.
-
-Heavy use is made of make's include facility and pattern rules. The 
-master rule set is in Tools/Makefile.inc.  Changes here will affect 
-almost every Makefile, and where exceptions are needed, the overrides 
-are applied in the lower Makefiles.
-
-These tools can run a windows-linux regression test, where all the 
-binaries are compared to a baseline windows build.

-	The propeller tools use bstc and openspin, parallax tools from 
-	http://www.fnarfbargle.com/bst.html 
-	https://github.com/parallaxinc/OpenSpin Note that bst is not 
-	open source or even currently maintained, so I could not 
-	generate a version for 64 bit macOS.
-
-	cpmtools were the most current I could find, and it has been 
-	hacked to do case-insensitivity. These are not marked, and are 
-	not extensive.
-
-	zxcc is from the distributed version, and also has local hacks 
-	for case insensitivity.
-
-	Both zxcc and cpmtools ship with an overly complicated makefile 
-	generation system and this is ignored.
