23;;; Commentary:
24
25;; Maildir format is documented at <URL:http://cr.yp.to/proto/maildir.html>
26;; and in the maildir(5) man page from qmail (available at
27;; <URL:http://www.qmail.org/man/man5/maildir.html>). nnmaildir also stores
28;; extra information in the .nnmaildir/ directory within a maildir.
29;;
30;; Some goals of nnmaildir:
31;; * Everything Just Works, and correctly. E.g., NOV data is automatically
32;; regenerated when stale; no need for manually running
33;; *-generate-nov-databases.
34;; * Perfect reliability: [C-g] will never corrupt its data in memory, and
35;; SIGKILL will never corrupt its data in the filesystem.
36;; * Allow concurrent operation as much as possible. If files change out
37;; from under us, adapt to the changes or degrade gracefully.
38;; * We use the filesystem as a database, so that, e.g., it's easy to
39;; manipulate marks from outside Gnus.
40;; * All information about a group is stored in the maildir, for easy backup,
41;; copying, restoring, etc.
42;;
43;; Todo:

MB
44;; * When moving an article for expiry, copy all the marks except 'expire
45;; from the original article.
23f87bed
MB
46;; * Add a hook for when moving messages from new/ to cur/, to support
47;; nnmail's duplicate detection.
48;; * Improve generated Xrefs, so crossposts are detectable.
49;; * Improve code readability.
