26 ;; Maildir format is documented in the maildir(5) man page from qmail
27 ;; and at <URL:http://cr.yp.to/proto/maildir.html>. nnmaildir also
28 ;; stores extra information in the .nnmaildir/ directory within a
31 ;; Some goals of nnmaildir:
32 ;; * Everything Just Works, and correctly. E.g., stale NOV data is
33 ;; ignored; no need for -generate-nov-databases.
34 ;; * Perfect reliability: [C-g] will never corrupt its data in memory,
35 ;; and SIGKILL will never corrupt its data in the filesystem.
36 ;; * We use the filesystem as a database, so that, e.g., it's easy to
37 ;; manipulate marks from outside Gnus.
38 ;; * All information about a group is stored in the maildir, for easy
39 ;; backup, copying, restoring, etc.
42 ;; * Don't force article renumbering, so nnmaildir can be used with
43 ;; the cache and agent. Alternatively, completely rewrite the Gnus
44 ;; backend interface, which would have other advantages.
46 ;; See also <URL:http://multivac.cwru.edu./nnmaildir/> until that
47 ;; information is added to the Gnus manual.
