The BTree classes implement the Python mapping interface.  They are
quite easy to use.  There are three kinds:

Object to Object 
Object to Integer
Integer to Object

All three kinds are used extensivly in the ZCatalog.  Other than that,
there isn't really any documentation.  They are basicly persistent
dictionaries that store their keys and values as BTrees.

intSet is like an 'array' of integers.  It implements the Python
sequence interface.  It was created to be more efficient than using
lists or tuples since they hold only integers.

There is some documentation on this in
lib/python/Components/ExtensionClass.

Now you can add these to the InterfaceWiki. ;)
