Originally contributed by Brian Sniffen [1]. Quite a few unpublished fixes from Daniel Kahn Gilmour. We've been running it a few years now as the "official" archive of the notmuch mailing list. There also a few fixes from myself and Austin Ray. Finally I converted it to the new python bindings. This commit squashes the several years of development history and moves it under devel, in recognition of the now established role it plays in the project infrastructure.
