+# Ex skeletal makefile for VAX VM/Unix version 7
+#
+# 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
