mujmap is a tool that synchronizes mail between a mail server and
notmuch via JMAP. It's very similar to lieer, so I heavily based the
implementation of the notmuch module on lieer's. I did not include an
equivalent to lieer's periodic synchronization service, however,
because I plan to soon introduce a daemon mode to mujmap.
