# 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), CHDIR (the 
# undocumented chdir command.)  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.
