Tools for synchronizing the tags in notmuch database.
Right now this just contains nmt.hs, a 3-way merge tool for the output of notmuch-dump(1). It is suitable for use as a merge driver in git.
However, notmuch-dump/notmuch-restore on the full tags database is
very slow when the database is large, so I plan to add tooling for
keeping things in sync while only having to extract recent changes to
the tags database. This is still TODO.
N.B. This is basically a re-write of notmuch-sync, which at the moment is at about the same level of functionality (though this one is a bit faster). It's hard to get me to write Python for free these days.
