+Yes, it seems to be quite trivial. I'll probably look at this tomorrow.\r

+My aim is only to store tags in git for the purpose of synchronization.\r
+I'm not interested in searching by tags. The idea is that for every\r

+\r
+Maildir is authoritative, but only for tags corresponding to maildir\r
+flags. Other tags are never touched by this code. See also the updated\r
+commit message in "[PATCH v2 3/4] Add maildir-based mailstore".\r
+\r
+If you want to sync your maildirs with the databse the following should\r
+work (not tested):\r
+\r
+notmuch dump > dump\r
+cat <<EOF >> ~/.notmuch-config\r
+[mailstore]\r
+type=maildir\r
+EOF\r
+notmuch restore dump\r
