+I just recently read [1] again, I think it's a good one.\r
+\r
+It makes me ask the question, why should we ask the user to make that\r

+whether to upgrade the database or not. Basically the decision is made\r
+when the user decides to upgrade notmuch. Once the user has upgraded\r
+notmuch his choices are to upgrade the database or downgrade notmuch.\r
+\r
+The user would probably just like to get on with the mail reading, which\r
+is probably also just means to an end!\r
