  dirs          a list of directions from where an entering character has to
                come to make that lib trigger (seperated by spaces).
                default: any direction
 
  delay         delay in pulses before the commands will be executed
                default: insta

  remember      after a character entered, do not trigger again for the given
                amount of pulses for just that character

  remember-any  after someone entered, do not trigger again for the given
                amount of pulses for any character

  act1          first command to be executed (e.g. wake) (*)
  act2          second possible command (*)
  act3          third possible command (*)

  act-delay     delay in pulses between the commands

  flags         optional flags: (seperated by spaces)

                nomob           do not trigger for mobs
                enemy           do trigger only for enemy races
                friend          do trigger only for non-enemy races
                nofight         do not trigger while fighting

  rooms         trigger only when coming from given rooms (seperated by spaces)


  (*) the 'act1-3' is done as 'force' on the mobile. So the $n, $N, $m etc
      are not available. But as a workaround I added following:
   
      - If you append $n to the very(!) end of the line, the force-command
        is targetted at the one who entered.

        Above does _not_ work for 'emote'.
