# combined Makefile for ELVIS - a clone of `vi`
#
# After editing this Makefile as described below, you should...
#
# Use `make` to compile all programs
# Use `make install` to copy the programs to the BIN directory
# Use `make clean` to remove all object files
# Use `make clobber` to remove everything except source & documentation
# Use `make uue` to produce uuencoded compressed tar archives of the source
# Use `make sh` to produce shar archives of the source
#
# Several groups of Makefile settings are included below.  Choose *ONE* group
# of settings for your particular system, and leave the others commented out.
# The meanings of these settings are:
#	OBJ	the filename extension for unlinked object files -- usually .o
#	EXE	filename extension for elvis executable file -- .exe, .tpp or null
#	COM	filename extension for executable support files -- .com, .tpp or null
#	EXTRA	version-specific object files used in elvis
#	EXTRA2	version-specific object files used in elvis & elvrec
#	LIBS	any special libraries, such as "-ltermcap"
#	BIN	directory where executables should be installed
#	SBIN	directory where system executables should be installed
#	CC	the C compiler command, possibly with "memory model" flags
#	CFLAGS	compiler flags used to select compile-time options
#	LNK	the linker command needed to link OBJ files (if not cc)
#	LFLAGS	linker flags used to select link-time options
#	SMALL	flag for special small memory model compilation -- usually null
#	OF	link flag to control the output file's name -- usually -o<space>
#	RF	flag used to denote "compile but don't link" -- usually -c
#	PROGS	the list of user programs
#	CHMEM	any extra commands to be run after ELVIS is linked
#	SORT	if the "tags" file must be sorted, then SORT=-DSORT
#	RM	the name of a program that deletes files
#	CP	name of a program that copies files -- copy or cp, usually
#	SYS	type of system & compiler: unx/tos/os9/dos (maybe vms?)
#	DUMMY	usually nothing, but OS9 needs "dummy"
#	CFG	name of compiler configuration file -- usually null

#---- These settings are recommended for Minix-vmd ----
