[ZODB-Dev] Problem with documentation and distribution files.

[Michael Twomey]

Hi,

  The BTree module in ZODB seems to have been replaced with the BTrees 
module which contains different types of btrees (the two letters at the 
beginning show how the key -> data is mapped, e.g. OOBTree is Object -> 
Object whereas IOBTree is int -> object). To get that example working 
simply change the offending lines to:

  # Ensure that a 'userdb' key is present
  if not dbroot.has_key('userdb'):
      from BTrees.OOBTree import OOBTree
      dbroot['userdb'] = OOBTree()

The above should work (I haven't tested it but I use similar stuff).
