-;; This file defines the command to search mails with Namazu and

-;; command Namazu. Visit the following page for more information.
+;; This file defines the command to search mails and persistent
+;; articles with Namazu and to browse its results with Gnus.
+;;
+;; Namazu is a full-text search engine intended for easy use. For
+;; more detail about Namazu, visit the following page:
;;
;; http://namazu.org/
+;;; Quick Start:
+
+;; If this module has already been installed, only 3 steps are
+;; required to search articles with this module.
+;;
+;; (1) Install Namazu.
+;; (2) Start Gnus and type M-x gnus-namazu-create-index RET to make
+;; index of articles.
+;; (3) In group buffer or in summary buffer, type C-c C-n query RET.
+
+
;;; Install:
-;; Make index of articles with Namzu before using this module.
+;; Before installing this module, you must install Namazu.
;;
-;; % mkdir ~/News/namazu
-;; % mknmz -a -h -O ~/News/namazu ~/Mail
+;; This file is a part of T-gnus but is not *YET* a part of Gnus.
+;; When you would like to use this module in Gnus (not T-gnus), put
+;; this file into the lisp/ directory in the Gnus source tree and run
+;; `make install'. And then, put the following expression into your
+;; ~/.gnus.
;;
-;; When you put index files of Namazu into the directory other than
-;; the default one (~/News/namazu), it is necessary to put this
-;; expression to your ~/.gnus, in order to set the path of index files
-;; to `gnus-namazu-index-directories'.
+;; (require 'gnus-namazu)
+;; (gnus-namazu-insinuate)
;;
-;; (setq gnus-namazu-index-directories
-;; (list (expand-file-name "~/namazu")))
+;; In order to make index of articles with Namazu before using this
+;; module, type M-x gnus-namazu-create-index RET. Otherwise, you can
+;; create index by yourself with the following commands:
;;
-;; If you would like to use this module in Gnus (not T-gnus), put this
-;; file into the lisp/ directory in the Gnus source tree and run `make
-;; install'. And then, put the following expressions into your ~/.gnus.
+;; % mkdir ~/News/namazu
+;; % mknmz -a -h -O ~/News/namazu ~/Mail ~/News/cache
;;
-;; (require 'gnus-namazu)
-;; (gnus-namazu-insinuate)
-
-
-;;; Usage:
-
-;; In group buffer or in summary buffer, type C-c C-n query RET.
+;; The first command makes the directory for index files, and the
+;; second command generates index files of mails and persistent
+;; articles.
+;;
+;; In order to update indices for incoming articles, this module
+;; automatically runs mknmz, the indexer of Namazu, at an interval of
+;; 3 days; this period is set to `gnus-namazu-index-update-interval'.
+;;
+;; Indices will be updated when `gnus-namazu-search' is called. If
+;; you want to update indices everywhen Gnus is started, you can put
+;; the following expression to your ~/.gnus.
+;;
+;; (add-hook 'gnus-startup-hook 'gnus-namazu-update-all-indices)
+;;
+;; In order to control mknmz closely, disable the automatic updating
+;; feature and run mknmz by yourself. In this case, set nil to the
+;; above option.
+;;
+;; (setq gnus-namazu-index-update-interval nil)
+;;
+;; When your index is put into the directory other than the default
+;; one (~/News/namazu), it is necessary to set its place to
+;; `gnus-namazu-index-directories' as follows:
+;;
+;; (setq gnus-namazu-index-directories
+;; (list (expand-file-name "~/namazu")))
;;; Code:
;; To suppress byte-compile warning.
