Section: Initial appearance, flexible appearance

Initial appearance is a description of something that is printed when the player looks and the object has not been moved. Tailored Room Description adds a "flexible appearance", which will be printed even if the object in question has been moved. So we might say

    The initial appearance of the cup is "Someone has casually tossed away a paper cup here."

so that after being moved it will simply be described in the collection of random objects; but
    
    The flexible appearance of the tripod is "A tripod is set up [if the location is indoors]on the floor[otherwise]on the ground[end if]."

so that the tripod will always have its own treatment, even if moved from room to room. If an item has both an initial appearance and a flexible appearance, the initial appearance will be consulted until the item is moved, and the flexible appearance afterward.
