25 ;; This is an emacs-based interface to the notmuch mail system.
27 ;; You will first need to have the notmuch program installed and have a
28 ;; notmuch database built in order to use this. See
29 ;; https://notmuchmail.org for details.
31 ;; To install this software, copy it to a directory that is on the
32 ;; `load-path' variable within emacs (a good candidate is
33 ;; /usr/local/share/emacs/site-lisp). If you are viewing this from the
34 ;; notmuch source distribution then you can simply run:
36 ;; sudo make install-emacs
40 ;; Then, to actually run it, add:
42 ;; (autoload 'notmuch "notmuch" "Notmuch mail" t)
44 ;; to your ~/.emacs file, and then run "M-x notmuch" from within emacs,
49 ;; Have fun, and let us know if you have any comment, questions, or
50 ;; kudos: Notmuch list <notmuch@notmuchmail.org> (subscription is not
51 ;; required, but is available from https://notmuchmail.org).
53 ;; Note for MELPA users (and others tracking the development version
56 ;; This emacs package needs a fairly closely matched version of the
57 ;; notmuch program. If you use the MELPA version of notmuch.el (as
58 ;; opposed to MELPA stable), you should be prepared to track the
59 ;; master development branch (i.e. build from git) for the notmuch
60 ;; program as well. Upgrading notmuch-emacs too far beyond the notmuch
61 ;; program can CAUSE YOUR EMAIL TO STOP WORKING.
