# NB: This makefile doesn't indicate any dependencies on header files.

# Ex is very large - this version will not fit on PDP-11's without overlay
15
# software.  Things that can be turned off to save
16
# space include LISPCODE (-l flag, showmatch and lisp options), CHDIR (the
17
# undocumented chdir command.)  VMUNIX makes ex considerably larger, raising
18
# many limits and improving speed and simplicity of maintenance.  It is
19
# suitable only for a VAX or other large machine, and then probably only in
20
# a paged system.
21
#
22
# Don't define VFORK unless your system has the VFORK system call,
23
# which is like fork but the two processes have only one data space until the
24
# child execs. This speeds up ex by saving the memory copy.
25
#
26
# If your system expands tabs to 4 spaces you should -DTABS=4 below
