From, uh, the documentation... because all of B's siblings will inherit
the same methods from A.

Ah, so *that's* how acquisition by context works! (I couldn't find any
documentation on this. All the documentation about acquisition by
context just says 'this is really complicated and I'm not going to
describe it here'.)

Unfortunately, this requires having the code dealing with text and
images to be in the same place, which breaks encapsulation.

It actually looks like acquisition by context is most likely my best bet
so far...

Incidentally, is it possible to override the default behaviour of an
object? Is there any way of allowing Rose/MyFavouriteRoseStories do
something *other* than just executing the named page template, other
than making MyFavouriteRoseStories a folder and overriding index_html?

Meh. Can you point me at any good tutorial documentations?
