 Some tips about how to do some useful things with notmuch, and the
 various "third party" notmuch utilities.

-  maildirectory to operate on.  Basically any setup in which each mail
-  is in a file of its own will work.  Here are some generally

-  * [offlineimap](https://github.com/nicolas33/offlineimap/) -
-    quite useful and widely tested, it also offers a handy hook that
-    will come in useful a bit later in our setup.  Also supports
-    "presynchook" and "postsynchook" command that will get run
-    whenever you sync.  Point _postsynchook_ to a script that gets run
-    on every sync and that will do the automatic updating and tagging
-    of your notmuch database.

-  Some IMAP users rely on maildir flags that convey the status "seen",
-  "replied", "trashed", in order to synchronize the status of their
-  mail across mail clients (a [maildir
-  flag](http://cr.yp.to/proto/maildir.html) is simply a defined part
-  of their filename).  Notmuch will by default happily ignore those
-  flags and will never modify them either, as there is no built-in
-  support for synchronizing your notmuch tags with your imap maildir
-  flags (seen, replied, trashed, etc). However there are currently 2
-  ways in which you can achieve synchronization.

-  The second solution allows for fast maildir flag to notmuch tag

-    The upside (if you are used to working in the context of a single folder)

-    and you are still in your original folder.
-    The downside is that this approach has scaling problems
-    and works well only for reasonably specific queries.
