+# 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

+# Revision 1.5  2001/08/07 00:15:51  richard
