SYNOPSIS
    mapping P_MAGIC_PROTECTION  "MagicProtection"

    mapping Set(P_MAGIC_PROTECTION, mapping value)
    mapping Query(P_MAGIC_PROTECTION)
      or
    mapping SetMagicProtection(mapping value)
    mapping QueryMagicProtection()

      Accessible via:
    string  AddMagicProtection (int type, string message)
    mapping ForbidAllMagic( [ string message ] )
    string  QueryIsMagicForbidden (int type)

DESCRIPTION
    The property describes which type of magic are forbidden in the room.
    The magic types are integers, defined in /sys/magic.h. For each type,
    an message has to be stored which will be printed upon attempt of such
    magic.
    All the data is stored in a mapping, indexed by the magic types, with
    the message strings as entries.

    The access to the property is easened by these lfuns:

    string  AddMagicProtection (int type, string message)
      Add a protection against magic <type> with <message> as the string
      to be printed. The string is also the return value.

    mapping ForbidAllMagic( [ string message ] )
      Forbid all types of magic. If <message> is given, it is the string
      printed upon attempt, else a default string is used.
      The lfun modifies P_MAGIC_PROTECTION and returns the new mapping
      as result.

    string  QueryIsMagicForbidden (int type)
      Check if magic <type> is forbidden. If yes, it returns the message
      string, if no, it returns 0.

EXAMPLE
    AddMagicProtection(ST_FIRE, "The walls absorb the energy.\n");
