SUPERSET and SUBSET were written out of frustration with the limitations
of the Osborne SETUP utility.  The present versions are not a complete
replacement for SETUP, but offer the following enhanced features:

1)	Sets of special function key definitions (including arrow keys)
	may be saved as CP/M files, which occupy 1K on double density
	and 2K on single density.  You can save as many of these files
	on a disk as you have room for, and you can easily change the
	set of definitions in use.

2)	SUPERSET also allows display and alteration of the command
	issued on cold boot, warm boot or both.  When function key
	definitions are saved as a file, the boot command is also
	saved.

3)	The command SUPERSET alone displays key settings and allows
	menu driven alterations, but command line arguments can also
	be used for abbreviated operations.  SUPERSET FILENAME will
	load key definitions from the named file.  (I.e., you can set
	SFK ^9 to "SUPERSET KEYDEFS2.KEY^M" so that hitting key ^9
	will rapidly load an alternate definition set.)  SUPERSET
	KEY K will allow editing of key K only with immediate exit.
	SUPERSET BOOT will allow changing the boot command only.

4)	SUPERSET and SUBSET are written in Software Toolworks C/80.  I
	have not checked whether they are compatible with the version
	of small C in the FOG library (probably not).  Those with
	some knowledge of C should have little trouble in making 
	their own modifications to the source code, which is included.
	A .ASM file for each program is also supplied, but note that 
	these files require the C/80 AS assembler and will NOT assemble 
	as is with the CP/M ASM.COM.

5)	SUPERSET and SUBSET can easily be configured for single or
	double density by #defining the word SD or DD in the header
	section, as explained in the .C file.  The density version
	of .COM files supplied is indicated by a 1 or 2 in the name.
	Users with a BIOS that does not start at E500 or E100 will 
	have to make the required adjustments to the macro table in 
	the header section and recompile the .c file.  Be careful with
	the function syswrit(), which writes edited definitions to
	the system tracks of a diskette, and could trash your system
	tracks if the addresses are wrong.

6)	SUBSET.COM is smaller than SUPERSET.COM (3k versus 7k) and
	includes only the ability to load files of key definitions
	created by SUPERSET.  It may be included on disks where you
	want to use multiple predefined key sets, but don't have
	enough space for SUPERSET.
