  This is a modules/control/rc.c look alike (with a bunch of new features)
 
  Use on local term:
-    vlc -I luarc
+    vlc -I rc
  Use on tcp connection:
-    vlc -I luarc --lua-config "rc={host='localhost:4212'}"
+    vlc -I rc --lua-config "rc={host='localhost:4212'}"
  Use on multiple hosts (term + 2 tcp ports):
-    vlc -I luarc --lua-config "rc={hosts={'*console','localhost:4212','localhost:5678'}}"
+    vlc -I rc --lua-config "rc={hosts={'*console','localhost:4212','localhost:5678'}}"
 
  Note:
-    -I luarc is an alias for -I lua --lua-intf rc
+    -I rc and -I luarc are aliases for -I lua --lua-intf rc
 
  Configuration options setable throught the --lua-config option are:
     * hosts: A list of hosts to listen on.
     * host: A host to listen on. (won't be used if `hosts' is set)
+    * eval: Add eval command to evaluate lua expressions. Set to any value to
+            enable.
  The following can be set using the --lua-config option or in the interface
  itself using the `set' command:
     * prompt: The prompt.
