 ;==================================================================================================
-;   RCBUS Z80 STANDARD CONFIGURATION
+;   ROMWBW DEFAULT BUILD SETTINGS FOR RCBUS EZ80
 ;==================================================================================================
 ;
-; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE
-; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY.  THIS FILE CONTAINS
-; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS.  IT IS INTENDED THAT YOU MAKE
-; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS.
-; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY
-; YOUR FILE IN THE BUILD PROCESS.
+; THIS FILE DEFINES THE DEFAULT CONFIGURATION SETTINGS FOR THE PLATFORM
+; INDICATED ABOVE.  THESE SETTINGS DEFINE THE OFFICIAL BUILD FOR THIS
+; PLATFORM AS DISTRIBUTED IN ROMWBW RELEASES.
 ;
-; THE SETTINGS BELOW ARE THE SETTINGS THAT ARE MOST COMMONLY MODIFIED FOR THIS PLATFORM.
-; MANY OF THEM ARE EQUAL TO THE SETTINGS IN THE INCLUDED FILE, SO THEY DON'T REALLY DO
-; ANYTHING AS IS.  THEY ARE LISTED HERE TO MAKE IT EASY FOR YOU TO ADJUST THE MOST COMMON
-; SETTINGS.
+; ROMWBW USES CASCADING CONFIGURATION FILES AS INDICATED BELOW:
 ;
-; N.B., SINCE THE SETTINGS BELOW ARE REDEFINING VALUES ALREADY SET IN THE INCLUDED FILE,
-; TASM INSISTS THAT YOU USE THE .SET OPERATOR AND NOT THE .EQU OPERATOR BELOW. ATTEMPTING
-; TO REDEFINE A VALUE WITH .EQU BELOW WILL CAUSE TASM ERRORS!

-; DIRECTORIES ABOVE THIS ONE).
+; THE TOP (MASTER CONFIGURATION) FILE DEFINES ALL POSSIBLE ROMWBW
+; CONFIGURATION SETTINGS. EACH FILE BELOW THE MASTER CONFIGURATION FILE
+; INHERITS THE CUMULATIVE SETTINGS OF THE FILES ABOVE IT AND MAY
+; OVERRIDE THESE SETTINGS AS DESIRED.
 ;
-#DEFINE	BOOT_DEFAULT	"H"		; DEFAULT BOOT LOADER CMD ON <CR> OR AUTO BOOT
+; OTHER THAN THE TOP MASTER FILE, EACH FILE MUST "#INCLUDE" ITS PARENT
+; FILE (SEE #INCLUDE STATEMENT BELOW).  THE TOP TWO FILES SHOULD NOT BE
+; MODIFIED.
 ;
-#include "cfg_rcez80.asm"
+; TO CUSTOMIZE YOUR BUILD SETTINGS YOU SHOULD MODIFY THIS FILE, THE

+; BUILD SETTINGS FILE (SEE EXAMPLE Config/SBC_user.asm).

-; INDICATED ABOVE. THIS FILE SHOULD *NOT* NORMALLY BE CHANGED.	INSTEAD, YOU SHOULD
-; OVERRIDE ANY SETTINGS YOU WANT USING A CONFIGURATION FILE IN THE CONFIG DIRECTORY

-;

+; YOU SHOULD OVERRIDE SETTINGS YOU WANT USING A CONFIGURATION FILE IN

+;
+; THIS FILE SHOULD *NOT* NORMALLY BE CHANGED.  IT IS MAINTAINED BY THE
+; AUTHORS OF ROMWBW.  TO OVERRIDE SETTINGS YOU SHOULD USE A
+; CONFIGURATION FILE IN THE CONFIG DIRECTORY UNDER THIS DIRECTORY.
+;
+; ROMWBW USES CASCADING CONFIGURATION FILES AS INDICATED BELOW:
+;
+; cfg_MASTER.asm			- MASTER: CONFIGURATION FILE DEFINES ALL POSSIBLE ROMWBW SETTINGS
+; |
+; +-> cfg_<platform>.asm		- PLATFORM: DEFAULT SETTINGS FOR SPECIFIC PLATFORM
+;     |

+;
+; THE TOP (MASTER CONFIGURATION) FILE DEFINES ALL POSSIBLE ROMWBW
+; CONFIGURATION SETTINGS. EACH FILE BELOW THE MASTER CONFIGURATION FILE
+; INHERITS THE CUMULATIVE SETTINGS OF THE FILES ABOVE IT AND MAY
+; OVERRIDE THESE SETTINGS AS DESIRED.
+;
+; OTHER THAN THE TOP MASTER FILE, EACH FILE MUST "#INCLUDE" ITS PARENT
+; FILE (SEE #INCLUDE STATEMENT BELOW).  THE TOP TWO FILES SHOULD NOT BE
+; MODIFIED.  TO CUSTOMIZE YOUR BUILD SETTINGS YOU SHOULD MODIFY THE
+; DEFAULT BUILD SETTINGS (Config/<platform>_std.asm) OR PREFERABLY
+; CREATE AN OPTIONAL CUSTOM USER SETTINGS FILE THAT INCLUDES THE DEFAULT
+; BUILD SETTINGS FILE (SEE EXAMPLE Config/SBC_user.asm).
+;
+; BY CREATING A CUSTOM USER SETTINGS FILE, YOU ARE LESS LIKELY TO BE
+; IMPACTED BY FUTURE CHANGES BECAUSE YOU WILL BE INHERITING MOST
+; OF YOUR SETTINGS WHICH WILL BE UPDATED BY AUTHORS AS ROMWBW EVOLVES.
+;
+; *** WARNING: ASIDE FROM THE MASTER CONFIGURATION FILE, YOU MUST USE
+; ".SET" TO OVERRIDE SETTINGS.  THE ASSEMBLER WILL ERROR IF YOU ATTEMPT
+; TO USE ".EQU" BECAUSE IT WON'T LET YOU REDEFINE A SETTING WITH ".EQU".
