[ZODB-Dev] BTree replaced by BTrees?

[Edward Hartley]

Hi
I'm just familiarizing myself with v3.1 of Standalone ZODB
which I've built and downloaded from Sourceforge.
Section 2.4 of the guide refers  to using BTree which is not available 
for import
in the version I have built.
an earlier post to this list notes that the 3.1 build tree dose not 
include
BTree.
Can assume that this is completely superseded by  the various BTrees 
variants
now available?
Thanks in Advance
Regards
Ed Hartley
