-# Revision 1.10  2002/01/22 07:08:50  richard
-# I was certain I'd already done this (there's even a change note in
-# CHANGES)...
-#
-# Revision 1.9  2001/12/12 02:30:51  richard
-# I fixed the problems with people whose anydbm was using the dbm module at the
-# backend. It turns out the dbm module modifies the file name to append ".db"
-# and my check to determine if we're opening an existing or new db just
-# tested os.path.exists() on the filename. Well, no longer! We now perform a
-# much better check _and_ cope with the anydbm implementation module changing
-# too!
-# I also fixed the backends __init__ so only ImportError is squashed.
-#
-# Revision 1.8  2001/12/10 22:20:01  richard
-# Enabled transaction support in the bsddb backend. It uses the anydbm code
-# where possible, only replacing methods where the db is opened (it uses the
-# btree opener specifically.)
-# Also cleaned up some change note generation.
-# Made the backends package work with pydoc too.
-#
-# Revision 1.7  2001/12/10 00:57:38  richard
-# From CHANGES:
-#  . Added the "display" command to the admin tool - displays a node's values
-#  . #489760 ] [issue] only subject
-#  . fixed the doc/index.html to include the quoting in the mail alias.
-#
-# Also:
-#  . fixed roundup-admin so it works with transactions
-#  . disabled the back_anydbm module if anydbm tries to use dumbdbm
-#
-# Revision 1.6  2001/08/07 00:24:42  richard
-# stupid typo
-#
-# Revision 1.5  2001/08/07 00:15:51  richard
-# Added the copyright/license notice to (nearly) all files at request of
-# Bizar Software.
