# 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.
