The "reference" section of the documentation should contain a patch
demonstrating how to use each of Pd's classes. As of version 0.29, a complete
list of "object" classes follows. Not included in this list are messages,
atoms, graphs, etc. which aren't typed into object boxes but come
straight off the "add" menu.
