I looked through the source and got a general sort of overview (I think--although I didn't completely understand what it's up to). Basically it seems to let you define a scenery object that is only lookable-at and not gettable, with a bunch of different "sub-objects".

Now, the former is handled by the scenery class in Hugo's object library. The only advantage to the latter that I can see is in Inform's (well, the z-machine's) limit on numbers of objects in a game.

My frigging copy of Agent is apparently busted as I can't find anything that looks like a "Send" button after writing a mail. But does anyone out there have a familiarity with that "scenic.h" thread? What does this library do in Inform?
