# Ex skeletal makefile for version 7
#
# NB: This makefile doesn't indicate any dependencies on header files.
#
# Ex is very large - it may not fit on PDP-11's depending on the operating
# system and the cflags you turn on. Things that can be turned off to save
# space include LISPCODE (-l flag, showmatch and lisp options), UCVISUAL
# (visual \ nonsense on upper case only terminals), CHDIR (the undocumented
# chdir command,)  RDONLY (-R flag, view), SOFTTABS (^T tabs), ZCMD (the
# various strange options after z plus ^F/^B), ZZCMD (ZZ from visual), WRAPMGN
# (wrapmargin), TAGSCODE (the tags feature), OPENCODE (open without visual),
# CRNL (code to support terminals with cr, nl, or ns attributes),
# BEEHIVE (superbee: f1=esc, f2=^c)
# Rule of thumb: OPENCODE will buy you about 2.5K, LISPCODE and TAGSCODE
# are worth perhaps 1.5K, and the others are worth fairly small amounts
# (mostly about 50-100 bytes).  UCVISUAL is worth a bit more (256?) and
# you should take it out unless you have such a terminal.
# Also make sure you are running the doprnt printf and not the portable
# one unless you have to run the portable one.
#
# Don't define VFORK unless your system has the VFORK system call,
# which is like fork but the two processes share memory until the
# child execs. This speeds up ex by saving the memory copy.

#
# Ex skeletal makefile for version 7
#
# NB: This makefile doesn't indicate any dependencies on header files.
#
# Ex is very large - it may not fit on PDP-11's depending on the operating
# system and the cflags you turn on. Things that can be turned off to save
# space include LISPCODE (-l flag, showmatch and lisp options), UCVISUAL
# (visual \ nonsense on upper case only terminals), CHDIR (the undocumented
# chdir command,)  RDONLY (-R flag, view), SOFTTABS (^T tabs), ZCMD (the
# various strange options after z plus ^F/^B), ZZCMD (ZZ from visual), WRAPMGN
# (wrapmargin), TAGSCODE (the tags feature), OPENCODE (open without visual),
# CRNL (code to support terminals with cr, nl, or ns attributes),
# BEEHIVE (superbee: f1=esc, f2=^c)
# Rule of thumb: OPENCODE will buy you about 2.5K, LISPCODE and TAGSCODE
# are worth perhaps 1.5K, and the others are worth fairly small amounts
# (mostly about 50-100 bytes).  UCVISUAL is worth a bit more (256?) and
# you should take it out unless you have such a terminal.
#
# Don't define VFORK unless your system has the VFORK system call,
# which is like fork but the two processes share memory until the
# child execs. This speeds up ex by saving the memory copy.
#
# If your system expands tabs to 4 spaces you should -DTABS=4 below
