;;; Commentary:
-;; THIS IS BETA SOFTWARE! This back end should not mess up or
-;; even delete your mails, but having a backup is always a good idea.
-
;; This is a back end for using the mairix search engine with
;; Gnus. Mairix is a tool for searching words in locally stored
;; mail. Mairix is very fast which allows using it efficiently for
;;
;; Mairix is written by Richard Curnow. More information can be found at
;; http://www.rpcurnow.force9.co.uk/mairix/
-;;
-;; For details about setting up mairix&Gnus&nnmairix.el, look at the
-;; emacswiki:
-;;
-;; http://www.emacswiki.org/cgi-bin/wiki/GnusMairix
-;;
-;; The newest version of nnmairix.el can be found at
-;;
-;; http://www.emacswiki.org/cgi-bin/emacs/nnmairix.el
-
-;; For impatient people, here's the setup in a nutshell:
-;;
-;; This back end requires an installed mairix binary which is
-;; configured to index your mail folder. You don't have to specify a
-;; search folder (but it does no harm, either). Visit the man page of
-;; mairix and mairixrc for details.
-;;
-;; Put nnmairix.el into your search path and "(require 'nnmarix)" into
-;; your .gnus. Then call nnmairix-create-default-group (or 'G b
-;; c'). This function will ask for all necessary information to create
-;; a mairix server in Gnus with the default search folder. This
-;; default search folder will be used for all temporary searches: call
-;; nnmairix-search ('G b s') and enter a mairix query (like
-;; f:test@example.com). To create a mairix group for one specific
-;; search query, use 'G b g'. See the emacswiki or the source for more
-;; information.
;; Commentary on the code: nnmairix sits between Gnus and the "real"
;; back end which handles the mail (currently nnml, nnimap and
;; I thought it would be a "nice to have feature"...
;; KNOWN BUGS:
-;; * When using Maildir: path and filename of a mail can change due to
-;; reading/replying/etc. This can lead to dangling symlinks in
-;; nnmairix groups and it depends on the back end how well it deals
-;; with that (some IMAP servers out there may not be amused). Update the
-;; database ('G b u') and the group to fix it.
;; * Mairix does only support us-ascii characters.
;; TODO/MISSING FEATURES:
-;; * Possibility to propagate flags like seen, replied, ticked
-;; to original message
;; * Support of more back ends (nnmh, nnfolder, nnmbox...)?
;; * Maybe use an active file instead of group parameters?
-;; * Use "-a" when updating groups which are not newly created
-
+;; * Maybe use "-a" when updating groups which are not newly created?
+
;;; Changelog:
+;; 05/30/2008 - version 0.6
+;;
+;; * It is now possible to propagate marks from the nnmairix groups
+;; to the original messages (and for maildir also vice versa). See
+;; the docs for details on this feature - it's pretty delicate
+;; and currently needs a patched mairix binary to work smoothly.
+;;
+;; * Keep messages in nnmairix groups always read/unread
+;; (bound to 'G b r').
+;;
+;; * Recreate back end folder for nnmairix groups in case you
+;; somehow get wrong article counts (bound to 'G b d').
+;;
+;; * New group parameter 'allow-fast'. Toggling of parameter bound
+;; to 'G b a'. The default is nil, meaning that the group will
+;; always be updated with a mairix search, even when only entered.
+;;
+;; * More/Better use of the registry (if available). Can now also
+;; deal with duplicate messages in different groups.
;;
;; 02/06/2008 - version 0.5
-;;
+;;
;; * New function: nnmairix-goto-original-article. Uses the
;; registry or the mail file path for determining original group.
-;;
+;;
;; * Deal with empty Xref header
;;
;; * Changed summary mode keybindings since the old ones were
;;
;; * New/fixed doc strings and code cleanup.
;;
-;; 18/11/2007 - version 0.3
+;; 11/18/2007 - version 0.3
;;
;; * Fixed bugs when dealing with nnml and native servers
-;;
+;;
;; * Make variables customizable
;;
;; 10/10/2007 - version 0.2
;;
;; * Use nnml-directory/directory server variables for nnml and
-;; nnmaildir backends as path for search folders. This way it
+;; nnmaildir back ends as path for search folders. This way it
;; becomes independent of 'base' setting in .mairixirc (but not for
;; nnimap).
;;
;; * As a result: Changed nnmairix-backend-to-server so that user
;; is asked when more than one nnmairix server exists and we do not
-;; know which one is responsible for current backend.
+;; know which one is responsible for current back end.
;;
-;; * Rename files when using nnml backends so that there are no
+;; * Rename files when using nnml back ends so that there are no
;; holes in article numbers. This should fix all problems regarding
;; wrong article counts with nnml.
