It is pretty big and there are a couple places where the series could be simplified, the first patch in particular. I will break it out and resubmit piecewise but I&#39;d like to know how to address these particular issues:<br>

<br>1. Are URIs  the way to specify individual messages, despite bremner&#39;s concerns about too much of the API being strings? Is adding another library is the easiest way to parse URIs?<br><br>2. Is it OK to break maildir relocatability, or  is it worth it to pass more config to the library (perhaps by adding it to the notmuch_database_t object)?<br>

<br>3. Is a global variable in the library  acceptable? (I don&#39;t see any others.) If not, how to store mailstore state?<br><br>The patch series is really more like a very rough draft to try to give these concerns a context (specifically, mbox support).<br>
