# Ex skeletal makefile for VAX VM/Unix 4.2BSD
#
# 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
# software.  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.)  CRYPT includes the code to edit encrypted files (the -x
# option, like ed.)  VMUNIX makes ex considerably larger, raising many limits
# and improving speed and simplicity of maintenance.  It is suitable only
# for a VAX or other large machine, and then probably only in a paged system.
#
# Don't define VFORK unless your system has the VFORK system call,
# which is like fork but the two processes have only one data space 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
