-# A more flexible way of restricting access to your server is the use
-# of "restriction lines". These tell the server to start up an (external)
-# program, upon whose output is decided whether the client is allowed
-# access. The program should print "Y" or "N <reason>" on its stdout.
-# Note that the use of R: lines is discouraged and deprecated, needs a
-# compile-time define, eats CPU cycles and may well be taken out in
-# future releases of ircd.
