-# + pass 'indexme="yes"' as a String() property initialisation arg, eg:
-# file = FileClass(db, "file", name=String(), type=String(),
-# comment=String(indexme="yes"))
-# + the comment will then be indexed and be searchable, with the results
-# related back to the issue that the file is linked to
-#- as a result of this work, the FileClass has a default MIME type that may
-# be overridden in a subclass, or by the use of a "type" property as is

-#- the regeneration of the indexes (if necessary) is done once the schema is

-#Sorry for the huge checkin message - I was only intending to implement #496356

-# . modified ROUNDUPDBSENDMAILDEBUG to be SENDMAILDEBUG and hold a filename
-# for _all_ roundup-generated smtp messages to be sent to.
-# . the transaction cache had broken the roundupdb.Class set() reactors
-# . newly-created author users in the mailgw weren't being committed to the db
-#
-#Stuff that made it into CHANGES.txt (ie. the stuff I was actually working
-#on when I found that stuff :):

-#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 1.14 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 1.13 2001/12/02 05:06:16 richard
-#. We now use weakrefs in the Classes to keep the database reference, so

-# I bumped the minimum python requirement up to 2.1 accordingly.

-#. #487476 ] INSTALL.txt
-#
-#I also cleaned up the change message / post-edit stuff in the cgi client.
-#There's now a clearly marked "TODO: append the change note" where I believe
-#the change note should be added there. The "changes" list will obviously
-#have to be modified to be a dict of the changes, or somesuch.
-#
-#More testing needed.
-#
-#Revision 1.12 2001/12/01 07:17:50 richard
-#. We now have basic transaction support! Information is only written to
-# the database when the commit() method is called. Only the anydbm
-# backend is modified in this way - neither of the bsddb backends have been.
-# The mail, admin and cgi interfaces all use commit (except the admin tool
-# doesn't have a commit command, so interactive users can't commit...)
-#. Fixed login/registration forwarding the user to the right page (or not,
-# on a failure)

-#Moved the data stringification up into the hyperdb.Class class' get, set
