I think the API docs are the right place, probably section 10. Notice
that it is very easy to move text from one section to another, so
don't worry too much about where this text ends up.
More worrying is the fact that new-style classes aren't documented at
all. There is nothing wrong, IMO, to start with a piece as obscure as
the PyType_Ready function, and I'm not asking that you produce a full
newstyle classes specification. However, it would be good if you could
allocate a subsection to all aspects of newstyle classes on the C
level that you can think of, perhaps filling in the parts that you
have been using.
Notice that the API documentation currently does not even *list* what
the slots in a type object are, or what the possible flags are. Some
of it is explained in the embedding and extending tutorial, but that
is the wrong place if you want comprehensiveness. So I'd envision the
10.3: Type Objects
Mentions all the slots; subsections elaborate
10.3.1 Mapping Object Structures (what is currently 10.3)
10.3.7 Rich Comparisons
10.3.8 Weak references
10.3.10 Object lifecycle
10.4 Inheriting Type Objects
As I said, the precise structure can be shifted once the text is there.
Hope this can get you started.
