CALLDOOR-INSIDE "part1 of calldoor lib: inside-room"
        
                The calldoor library consists of two libraries. CALLDOOR-INSIDE
                and CALLDOOR-OUTSIDE. Calldoor-inside triggers on 'say open',
                while calldoor-ouside triggers on 'call'.

  <door>        door name
  <flags>       (not implemented yet)
  <mob>         mobile vnum of the gatekeeper
  <timeout>     until the gatekeeper tried to close again (in pulses)


IMPORTANT:
  - two CALLDOOR-INSIDE libs in the same room will make the first calldoor
    lib unusable! 


Notes:

  - currently the gatekeeper mob only reacts to players of the same side or
    if it is set to neutral, it reacts to all

  - to make the door unusable by open/close attempts of players, you can use
    the 'heavy-door' lib and set the variable 'needstr' to a very high value.
    Make sure you set the str sufficiantly high on the gatekeeper mobile.

  - you might want to LOCK the door by /com (on both sides!)
