+;;; Commentary:
+;;
+;; WARNING: This package is still under construction and not all of
+;; the features below are implemented.
+;;
+;; This package provides a framework for adding user friendly
+;; customization support to Emacs. Having to do customization by
+;; editing a text file in some arcane syntax is user hostile in the
+;; extreme, and to most users emacs lisp definitely count as arcane.
+;;
+;; The intension is that authors of emacs lisp packages declare the
+;; variables intended for user customization with `custom-declare'.
+;; Custom can then automatically generate a customization buffer with
+;; `custom-buffer-create' where the user can edit the package
+;; variables in a simple and intuitive way, as well as a menu with
+;; `custom-menu-create' where he can set the more commonly used
+;; variables interactively.
+;;
+;; It is also possible to use custom for modifying the properties of
+;; other objects than the package itself, by specifying extra optional
+;; arguments to `custom-buffer-create'.
+;;
+;; Custom is inspired by OPEN LOOK property windows.
+
+;;; Todo:
+;;
+;; - Toggle documentation in three states `none', `one-line', `full'.
+;; - Function to generate an XEmacs menu from a CUSTOM.
+;; - Write TeXinfo documentation.
+;; - Make it possible to hide sections by clicking at the level.
+;; - Declare AUC TeX variables.
+;; - Declare (ding) Gnus variables.
+;; - Declare Emacs variables.
+;; - Implement remaining types.
+;; - XEmacs port.
+;; - Allow `URL', `info', and internal hypertext buttons.
+;; - Support meta-variables and goal directed customization.
+;; - Make it easy to declare custom types independently.
+;; - Make it possible to declare default value and type for a single
+;; variable, storing the data in a symbol property.
+;; - Syntactic sugar for CUSTOM declarations.
+;; - Use W3 for variable documenation.

+Each time you read an article it will be marked as read. Likewise, if
+you delete it it will be marked as deleted, and if you tick it it will
+be marked as ticked. When you leave a group, GNUS can automatically
+create score file entries based on these marks, so next time you enter
+the group articles with subjects that you read last time have higher
+score and articles with subjects that deleted will have lower score.
+
+Below is a list of such marks. You can insert new marks to the list
+by pushing on one of the `[INS]' buttons in the left margin to create
+a new entry and then pushing the `Mark' button to select the mark.
+For each mark there is another list, this time of article headers,
+which determine how the mark should affect that header. The `[INS]'
+buttons of this list are indented to indicate that the belong to the
+mark above. Push the `Header' button to choose a header, and then
+enter a score value in the `Score' field.
+
+For each article that are marked with `Mark' when you leave the
+group, a temporary score entry for the articles `Header' with the
+value of `Score' will be added the adapt file. If the score entry
+already exists, `Score' will be added to its value. If you understood
+that, you are smart.
+
+You can select the special value `Other' when pressing the `Mark' or
+`Header' buttons. This is because Lars might add more useful values
+there. If he does, it is up to you to figure out what they are named.")

+(defun gnus-kill-file-mode ()
+ "Major mode for editing kill files.
+
+If you are using this mode - you probably shouldn't. Kill files
+perform badly and paint with a pretty broad brush. Score files, on
+the other hand, are vastly faster (40x speedup) and give you more
+control over what to do.
+
+In addition to Emacs-Lisp Mode, the following commands are available:
+
+\\{gnus-kill-file-mode-map}
+
+ A kill file contains Lisp expressions to be applied to a selected
+newsgroup. The purpose is to mark articles as read on the basis of
+some set of regexps. A global kill file is applied to every newsgroup,
+and a local kill file is applied to a specified newsgroup. Since a
+global kill file is applied to every newsgroup, for better performance
+use a local one.
+
+ A kill file can contain any kind of Emacs Lisp expressions expected
+to be evaluated in the Summary buffer. Writing Lisp programs for this
+purpose is not so easy because the internal working of Gnus must be
+well-known. For this reason, Gnus provides a general function which
+does this easily for non-Lisp programmers.
+
+ The `gnus-kill' function executes commands available in Summary Mode
+by their key sequences. `gnus-kill' should be called with FIELD,
+REGEXP and optional COMMAND and ALL. FIELD is a string representing
+the header field or an empty string. If FIELD is an empty string, the
+entire article body is searched for. REGEXP is a string which is
+compared with FIELD value. COMMAND is a string representing a valid
+key sequence in Summary mode or Lisp expression. COMMAND defaults to
+'(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is
+executed in the Summary buffer. If the second optional argument ALL
+is non-nil, the COMMAND is applied to articles which are already
+marked as read or unread. Articles which are marked are skipped over
+by default.
+
+ For example, if you want to mark articles of which subjects contain
+the string `AI' as read, a possible kill file may look like:
+
+ (gnus-kill \"Subject\" \"AI\")
+
+ If you want to mark articles with `D' instead of `X', you can use
+the following expression:
+
+ (gnus-kill \"Subject\" \"AI\" \"d\")
+
+In this example it is assumed that the command
+`gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode.
+
+ It is possible to delete unnecessary headers which are marked with
+`X' in a kill file as follows:
+
+ (gnus-expunge \"X\")
+
+ If the Summary buffer is empty after applying kill files, Gnus will
+exit the selected newsgroup normally. If headers which are marked
+with `D' are deleted in a kill file, it is impossible to read articles
+which are marked as read in the previous Gnus sessions. Marks other
+than `D' should be used for articles which should really be deleted.
+
+Entry to this mode calls emacs-lisp-mode-hook and
+gnus-kill-file-mode-hook with no arguments, if that value is non-nil."

;; This file is part of GNU Emacs.
;;; Commentary:
-;; All gnus-uu commands start with `C-c C-v'.
-;;
-;; Short user manual for this package:
-;;
-;; Type `C-c C-v C-v' to decode and view all articles of the current
-;; series. The defaults should be reasonable for most systems.
-;;
-;; Type `C-c C-v C-i' to toggle interactive mode. When using
-;; interactive mode, gnus-uu will which display a buffer that will let
-;; you see the suggested commands to be executed.
-;;
-;; To post an uuencoded file, type `C-c C-v p', which will enter you
-;; into a buffer analogous to the one you will get when typing `a'. Do
-;; an `M-x describe-mode' in this buffer to get a description of what
-;; this buffer lets you do.
-;;
-;; Read the documentation of the `gnus-uu' dummy function for a more
-;; complete description of what this package does and how you can
-;; customize it to fit your needs.
-;;
-;;
-;;
-;; History
-;;
-;; v1.0: First version released Oct 2 1992.
-;;
-;; v1.1: Changed `C-c C-r' to `C-c C-e' and `C-c C-p' to `C-c C-k'.
-;; Changed (setq gnus-exit-group-hook) to (add-hook). Removed
-;; checking for "Re:" for finding parts.
-;;
-;; v2.2: Fixed handling of currupted archives. Changed uudecoding to
-;; an asynchronous process to avoid loading tons of data into emacs
-;; buffers. No longer reads articles emacs already have aboard. Fixed
-;; a firmer support for shar files. Made regexp searches for files
-;; more convenient. Added `C-c C-l' for editing uucode begin
-;; lines. Added multi-system decoder entry point. Added interactive
-;; view mode. Added function for decoding and saving all uuencoded
-;; articles in the current newsgroup.
-;;
-;; v2.3: After suggestions I have changed all the gnus-uu key bindings
-;; to avoid hogging all the user keys (C-c LETTER). Also added
-;; (provide) and fixed some saving stuff. First posted version to
-;; gnu.emacs.sources.
-;;
-;; v2.4: Fixed some more in the save-all category. Automatic fixing of
-;; uucode "begin" lines: names on the form of "dir/file" are
-;; translated into "dir-file". Added a function for fixing stripped
-;; uucode articles. Added binhex save.
-;;
-;; v2.5: First version copyrighted by FSF. Changed lots of
-;; documentation strings.
-;;
-;; v2.5.1: Added uuencode/posting code to post binary files.
-;;
-;; v2.6: Thread support. gnus-uu is now able to decode uuencoded files
-;; posted in threads. gnus-uu can also post in threads. I don't know
-;; if this ability is of much use - I've never seen anyone post
-;; uuencoded files in threads.
-;;
-;; v2.7: gnus-uu is now able to decode (and view/save) multiple
-;; encoded files in one big gulp. Also added pseudo-mime support
-;; (users can use metamail to view files), posting uuencoded/mime
-;; files and various other bits and pieces.
-;;
-;; v2.7.1: New functions for decoding/saving threads bound to `C-c
-;; C-v C-j'. Handy to save entire threads, not very useful for
-;; decoding, as nobody posts encoded files in threads...
-;;
-;; v2.7.2: New functions for digesting and forwarding articles added
-;; on the suggestion of Per Abrahamsen. Also added a function for
-;; marking threads.
-;;
-;; v2.8: Fixed saving original files in interactive mode. Fixed ask
-;; before/save after view. Fixed setting up interactive buffers. Added
-;; scanning and rescanning from interactive mode. Added the
-;; `gnus-uu-ignore-file-by-name' and `...-by-type' variables to allow
-;; users to sift files they don't want to view. At the suggestion of
-;; boris@cs.rochester.edu, `C-c C-v C-h' has been undefined to allow
-;; users to view list of binding beginning with `C-c C-v'. Fixed
-;; viewing with `gnus-uu-asynchronous' set. The
-;; "decode-and-save/view-all-articles" functions now accepts the
-;; numeric prefix to delimit the maximum number of files to be
-;; decoded.
-
;;; Code:
(require 'gnus)
-(require 'gnuspost)

-Function description:
-
-`gnus-uu-decode-and-view' will try to find all articles in the same
-series, uudecode them and view the resulting file(s).
-
-gnus-uu guesses what articles are in the series according to the
-following simplish rule: The subjects must be (nearly) identical,
-except for the last two numbers of the line. (Spaces are largely
-ignored, however.)
-
-For example: If you choose a subject called
- \"cat.gif (2/3)\"
-gnus-uu will find all the articles that matches
- \"^cat.gif ([0-9]+/[0-9]+).*$\".
-
-Subjects that are nonstandard, like
- \"cat.gif (2/3) Part 6 of a series\",
-will not be properly recognized by any of the automatic viewing
-commands, and you have to mark the articles manually with '#'.
-
-`gnus-uu-decode-and-save' will do the same as
-`gnus-uu-decode-and-view', except that it will not display the
-resulting file, but save it instead.
-
-`gnus-uu-shar-and-view' and `gnus-uu-shar-and-save' are the \"shar\"
-equivalents to the uudecode functions. Instead of feeding the articles
-to uudecode, they are run through /bin/sh. Most shar files can be
-viewed and/or saved with the normal uudecode commands, which is much
-safer, as no foreign code is run.
-
-Instead of having windows popping up automatically, it can be handy to
-view files interactivly, especially when viewing archives. Use
-`gnus-uu-toggle-interactive-mode' to toggle interactive mode.
-
-`gnus-uu-mark-article' marks an article for later
-decoding/unsharing/saving/viewing. The files will be decoded in the
-sequence they were marked. To decode the files after you've marked the
-articles you are interested in, type the corresponding key strokes as
-the normal decoding commands, but put a `M-' in the last
-keystroke. For instance, to perform a standard uudecode and view, you
-would type `C-c C-v C-v'. To perform a marked uudecode and view, say
-`C-v C-v M-C-v'. All the other view and save commands are handled the
-same way; marked uudecode and save is then `C-c C-v M-v'.
-
-`gnus-uu-unmark-article' will remove the mark from a previosly marked
-article.
-
-`gnus-uu-unmark-all-articles' will remove the mark from all marked
-articles.
-
-`gnus-uu-mark-by-regexp' will prompt for a regular expression and mark
-all articles matching that regular expression.
-
-`gnus-uu-mark-thread' will mark all articles downward in the current
-thread.
-
-There's an additional way to reach the decoding functions to make
-future expansions easier: `gnus-uu-multi-decode-and-view' and the
-corresponding save, marked view and marked save functions. You will be
-prompted for a decoding method, like uudecode, shar, binhex or plain
-save. Note that methods like binhex and save doesn't have view modes;
-even if you issue a view command (`C-c C-v C-m' and \"binhex\"),
-gnus-uu will just save the resulting binhex file.
-
-`gnus-uu-decode-and-show-in-buffer' will decode the current article
-and display the results in an emacs buffer. This might be useful if
-there's jsut some text in the current article that has been uuencoded
-by some perverse poster.
-
-`gnus-uu-decode-and-save-all-articles' looks at all the articles in
-the current newsgroup and tries to uudecode everything it can
-find. The user will be prompted for a directory where the resulting
-files (if any) will be
-saved. `gnus-uu-decode-and-save-unread-articles' does only checks
-unread articles.
-
-`gnus-uu-decode-and-view-all-articles' does the same as the function
-above, only viewing files instead of saving them.
-
-`gnus-uu-edit-begin-line' lets you edit the begin line of an uuencoded
-file in the current article. Useful to change a corrupted begin line.
-
-
-When using the view commands, `gnus-uu-decode-and-view' for instance,
-gnus-uu will (normally, see below) try to view the file according to
-the rules given in `gnus-uu-default-view-rules' and
-`gnus-uu-user-view-rules'. If it recognizes the file, it will display
-it immediately. If the file is some sort of archive, gnus-uu will
-attempt to unpack the archive and see if any of the files in the
-archive can be viewed. For instance, if you have a gzipped tar file
-\"pics.tar.gz\" containing the files \"pic1.jpg\" and \"pic2.gif\",
-gnus-uu will uncompress and detar the main file, and then view the two
-pictures. This unpacking process is recursive, so if the archive
-contains archives of archives, it'll all be unpacked.
-
-If the view command doesn't recognise the file type, or can't view it
-because you don't have the viewer, or can't view *any* of the files in
-the archive, the user will be asked if she wishes to have the file
-saved somewhere. Note that if the decoded file is an archive, and
-gnus-uu manages to view some of the files in the archive, it won't
-tell the user that there were some files that were unviewable. Try
-interactive view for a different approach.
-
-
-Note that gnus-uu adds a function to `gnus-exit-group-hook' to clear
-the list of marked articles and check for any generated files that
-might have escaped deletion if the user typed `C-g' during viewing.
-
-
-`gnus-uu-toggle-asynchronous' toggles the `gnus-uu-asynchronous'
-variable.
-
-`gnus-uu-toggle-query' toggles the `gnus-uu-ask-before-view'
-variable.
-
-`gnus-uu-toggle-always-ask' toggles the `gnus-uu-view-and-save'
-variable.
-
-`gnus-uu-toggle-kill-carriage-return' toggles the
-`gnus-uu-kill-carriage-return' variable.
-
-`gnus-uu-toggle-interactive-view' toggles interactive mode. If it is
-turned on, gnus-uu won't view files immediately, but will give you a
-buffer with the default commands and files and let you edit the
-commands and execute them at leisure.
-
-`gnus-uu-toggle-correct-stripped-articles' toggles whether to check
-and correct uuencoded articles that may have had trailing spaces
-stripped by mailers.
-
-`gnus-uu-toggle-view-with-metamail' toggles whether to skip the
-gnus-uu viewing methods and just guess at an content-type based on the
-file name suffix and feed it to metamail.
-
-`gnus-uu-toggle-any-variable' is an interface to the toggle commands
-listed above.

-
- Rule Variables
-
- gnus-uu uses \"rule\" variables to decide how to view a file. All
- these variables are of the form
-
- (list '(regexp1 command2)
- '(regexp2 command2)
- ...)
-
- `gnus-uu-user-view-rules'
- This variable is consulted first when viewing files. If you wish
- to use, for instance, sox to convert an .au sound file, you could
- say something like:
-
- (setq gnus-uu-user-view-rules
- (list '(\"\\\\.au$\" \"sox %s -t .aiff > /dev/audio\")))
-
- `gnus-uu-user-view-rules-end'
- This variable is consulted if gnus-uu couldn't make any matches
- from the user and default view rules.
-
- `gnus-uu-user-interactive-view-rules'
- This is the variable used instead of `gnus-uu-user-view-rules'
- when in interactive mode.
-
- `gnus-uu-user-interactive-view-rules-end'
- This variable is used instead of `gnus-uu-user-view-rules-end'
- when in interactive mode.
-
- `gnus-uu-user-archive-rules`
- This variable can be used to say what comamnds should be used to
- unpack archives.
-
-
- Other Variables
-
- `gnus-uu-ignore-files-by-name'
- Files with name matching this regular expression won't be viewed.
-
- `gnus-uu-ignore-files-by-type'
- Files with a MIME type matching this variable won't be viewed.
- Note that gnus-uu tries to guess what type the file is based on
- the name. gnus-uu is not a MIME package, so this is slightly
- kludgy.
-
- `gnus-uu-tmp-dir'
- Where gnus-uu does its work.
-
- `gnus-uu-do-not-unpack-archives'
- Non-nil means that gnus-uu won't peek inside archives looking for
- files to dispay.
-
- `gnus-uu-view-and-save'
- Non-nil means that the user will always be asked to save a file
- after viewing it.
-
- `gnus-uu-asynchronous'
- Non-nil means that files will be viewed asynchronously. This can
- be useful if you're viewing long .mod files, for instance, which
- often takes several minutes. Note, however, that since gnus-uu
- doesn't ask, and if you are viewing an archive with lots of
- viewable files, you'll get them all up more or less at once,
- which can be confusing, to say the least. To get gnus-uu to ask
- you before viewing a file, set the `gnus-uu-ask-before-view'
- variable.
-
- `gnus-uu-ask-before-view'
- Non-nil means that gnus-uu will ask you before viewing each file
-
- `gnus-uu-ignore-default-view-rules'
- Non-nil means that gnus-uu will ignore the default viewing rules.
-
- `gnus-uu-ignore-default-archive-rules'
- Non-nil means that gnus-uu will ignore the default archive
- unpacking commands.
-
- `gnus-uu-kill-carriage-return'
- Non-nil means that gnus-uu will strip all carriage returns from
- articles.
-
- `gnus-uu-unmark-articles-not-decoded'
- Non-nil means that gnus-uu will mark articles that were
- unsuccessfully decoded as unread.
-
- `gnus-uu-output-window-height'
- This variable says how tall the output buffer window is to be
- when using interactive view mode.
-
- `gnus-uu-correct-stripped-uucode'
- Non-nil means that gnus-uu will *try* to fix uuencoded files that
- have had traling spaces deleted.
-
- `gnus-uu-use-interactive-view'
- Non-nil means that gnus-uu will use interactive viewing mode.
-
- `gnus-uu-view-with-metamail'
- Non-nil means that gnus-uu will ignore the viewing commands
- defined by the rule variables and just fudge a MIME content type
- based on the file name. The result will be fed to metamail for
- viewing.
-
- `gnus-uu-save-in-digest'
- Non-nil means that gnus-uu, when asked to save without decoding,
- will save in digests. If this variable is nil, gnus-uu will just
- save everything in a file without any embellishments. The
- digesting almost conforms to RFC1153 - no easy way to specify any
- meaningful volume and issue numbers were found, so I simply
- dropped them.
-
- `gnus-uu-post-include-before-composing'
- Non-nil means that gnus-uu will ask for a file to encode before
- you compose the article. If this variable is t, you can either
- include an encoded file with \\<gnus-uu-post-reply-mode-map>\\[gnus-uu-post-insert-binary-in-article] or have one included for you when you
- post the article.
-
- `gnus-uu-post-length'
- Maximum length of an article. The encoded file will be split
- into how many articles it takes to post the entire file.
-
- `gnus-uu-post-threaded'
- Non-nil means that gnus-uu will post the encoded file in a
- thread. This may not be smart, as no other decoder I have seen
- are able to follow threads when collecting uuencoded
- articles. (Well, I have seen one package that does that -
- gnus-uu, but somehow, I don't think that counts...) Default is
- nil.
-
- `gnus-uu-post-separate-description'
- Non-nil means that the description will be posted in a separate
- article. The first article will typically be numbered (0/x). If
- this variable is nil, the description the user enters will be
- included at the beginning of the first article, which will be
- numbered (1/x). Default is t.

-(defun gnus-uu-post-reply-mode ()
- "Major mode for editing binary news to be posted on USENET.
-First-time posters are asked to please read the articles in newsgroup:
- news.announce.newusers .
-
-Like news-reply-mode, which is like Text Mode, but with these
-additional commands:
-
-\\<gnus-uu-post-reply-mode-map>\\[gnus-uu-post-news-inews] post the message.
-C-c C-f move to a header field (and create it if there isn't):
- C-c C-f C-n move to Newsgroups: C-c C-f C-s move to Subj:
- C-c C-f C-f move to Followup-To: C-c C-f C-k move to Keywords:
- C-c C-f C-d move to Distribution: C-c C-f C-a move to Summary:
-C-c C-y news-reply-yank-original (insert current message, in NEWS).
-C-c C-q mail-fill-yanked-message (fill what was yanked).
-C-c C-r caesar rotate all letters by 13 places in the article's body (rot13).
-\\[gnus-uu-post-insert-binary-in-article] encode and include a file in this article.
-
-This mode is almost identical to news-reply-mode, but has some
-additional commands for treating encoded binary articles. In
-particular, \\[gnus-uu-post-news-inews] will ask for a file to include, if
-one hasn't been included already. It will post, first, the message
-composed, and then it will post as many additional articles it takes
-to post the entire encoded files.
-
- Relevant Variables
-
- `gnus-uu-post-encode-method'
- There are three functions supplied with gnus-uu for encoding files:
- `gnus-uu-post-encode-uuencode', which does straight uuencoding;
- `gnus-uu-post-encode-mime', which encodes with base64 and adds MIME
- headers; and `gnus-uu-post-encode-mime-uuencode', which encodes with
- uuencode and adds MIME headers.
-
- `gnus-uu-post-include-before-composing'
- Non-nil means that gnus-uu will ask for a file to encode before you
- compose the article. If this variable is t, you can either include
- an encoded file with `C-c C-i' or have one included for you when you
- post the article.
-
- `gnus-uu-post-length'
- Maximum length of an article. The encoded file will be split into how
- many articles it takes to post the entire file.
-
- `gnus-uu-post-separate-description'
- Non-nil means that the description will be posted in a separate
- article. The first article will typically be numbered (0/x). If
- this variable is nil, the description the user enters will be
- included at the beginning of the first article, which will be
- numbered (1/x). Default is t.
-
- `gnus-uu-post-threaded'
- Non-nil means that gnus-uu will post the encoded file in a thread.
- This may not be smart, as no other decoder I have seen are able to
- follow threads when collecting uuencoded articles. (Well, I have seen
- one package that does that - gnus-uu, but somehow, I don't think that
- counts...) Default is nil.

;; Keywords: news
;; This file is part of GNU Emacs.
;;; Commentary:
-;; How to Install GNUS:
-;; (0) First of all, remove GNUS related OLD *.elc files (at least
-;; nntp.elc).
-;; (1) Unshar gnus.el, gnuspost.el, gnusmail.el, gnusmisc.el, and
-;; nntp.el.
-;; (2) byte-compile-file nntp.el, gnus.el, gnuspost.el, gnusmail.el,
-;; and gnusmisc.el. If you have a local news spool,
-;; byte-compile-file nnspool.el, too.
-;; (3) Define three environment variables in .login file as follows:
-;;
-;; setenv NNTPSERVER flab
-;; setenv DOMAINNAME "stars.flab.Fujitsu.CO.JP"
-;; setenv ORGANIZATION "Fujitsu Laboratories Ltd., Kawasaki, Japan."
-;;
-;; Or instead, define lisp variables in your .emacs, site-init.el,
-;; or default.el as follows:
-;;
-;; (setq gnus-nntp-server "flab")
-;; (setq gnus-local-domain "stars.flab.Fujitsu.CO.JP")
-;; (setq gnus-local-organization "Fujitsu Laboratories Ltd., ...")
-;;
-;; If the function (system-name) returns the full internet name,
-;; you don't have to define the domain.
-;;
-;; (4) You may have to define NNTP service name as number 119.
-;;
-;; (setq gnus-nntp-service 119)
-;;
-;; Or, if you'd like to use a local news spool directly in stead
-;; of NNTP, set the variable to nil as follows:
-;;
-;; (setq gnus-nntp-service nil)
-;;
-;; (5) If you'd like to use the GENERICFROM feature like the Bnews,
-;; define the variable as follows:
-;;
-;; (setq gnus-use-generic-from t)
-;;
-;; (6) Define autoload entries in .emacs file as follows:
-;;
-;; (autoload 'gnus "gnus" "Read network news." t)
-;; (autoload 'gnus-post-news "gnuspost" "Post a news." t)
-;;
-;; (7) Read nntp.el if you have problems with NNTP or kanji handling.
-;;
-;; (8) Install mhspool.el, tcp.el, and tcp.c if it is necessary.
-;;
-;; mhspool.el is a package for reading articles or mail in your
-;; private directory using GNUS.
-;;
-;; tcp.el and tcp.c are necessary if and only if your Emacs does
-;; not have the function `open-network-stream' which is used for
-;; communicating with NNTP server inside Emacs.
-;;
-;; (9) Install an Info file generated from the texinfo manual gnus.texinfo.
-;;
-;; If you are not allowed to create the Info file to the standard
-;; Info-directory, create it in your private directory and set the
-;; variable gnus-info-directory to that directory.
-;;
-;; For getting more information about GNUS, consult USENET newsgorup
-;; gnu.emacs.gnus.
-
-;; TO DO:
-;; (1) Incremental update of active info.
-;; (2) Asynchronous transmission of large messages.
+;; Although Gnus looks suspiciously like GNUS, it isn't quite the same
+;; beast. Most internal structures have been changed. If you have
+;; written packages that depend on any of the hash tables,
+;; `gnus-newsrc-alist', `gnus-killed-assoc', marked lists, the .newsrc
+;; buffer, or internal knowledge of the `nntp-header-' macros, or
+;; dependence on the buffers having a certain format, your code will
+;; fail.

-
- The name of the host running NNTP server is asked for if no default
-host is specified. It is also possible to choose another NNTP server
-even when the default server is defined by giving a prefix argument to
-the command `\\[gnus]'.
-
- If the NNTP server name starts with a colon, as in `:Mail', the user's
-own directory `~/Mail' is used as a news spool. This makes it
-possible to read mail stored in MH folders or articles saved by GNUS.
-File names of mail or articles must consist of only numeric
-characters. Otherwise, they are ignored.
-
- If there is a file named `~/.newsrc-SERVER', it is used as the
-startup file instead of standard one when talking to SERVER. It is
-possible to talk to many hosts by using different startup files for
-each.
-
- Option `-n' of the options line in the startup file is recognized
-properly the same as the Bnews system. For example, if the options
-line is `options -n !talk talk.rumors', newsgroups under the `talk'
-hierarchy except for `talk.rumors' are ignored while checking new
-newsgroups.
-
- If there is a file named `~/.signature-DISTRIBUTION', it is used as
-signature file instead of standard one when posting a news in
-DISTRIBUTION.
-
- If an Info file generated from `gnus.texinfo' is installed, you can
-read an appropriate Info node of the Info file according to the
-current major mode of GNUS by \\[gnus-info-find-node].
-
- The variable `gnus-version', `nntp-version', `nnspool-version', and
-`mhspool-version' have the version numbers of this version of gnus.el,
-nntp.el, nnspool.el, and mhspoo.el, respectively.
-
-User customizable variables:
- gnus-nntp-server
- Specifies the name of the host running the NNTP server. If its
- value is a string such as `:DIRECTORY', the user's private
- DIRECTORY is used as a news spool. The variable is initialized
- from the NNTPSERVER environment variable.
-
- gnus-nntp-service
- Specifies a NNTP service name. It is usually \"nntp\" or 119.
- Nil forces GNUS to use a local news spool if the variable
- `gnus-nntp-server' is set to the local host name.
-
- gnus-startup-file
- Specifies a startup file (.newsrc). If there is a file named
- `.newsrc-SERVER', it's used instead when talking to SERVER. I
- recommend you to use the server specific file, if you'd like to
- talk to many servers. Especially if you'd like to read your
- private directory, the name of the file must be
- `.newsrc-:DIRECTORY'.
-
- gnus-signature-file
- Specifies a signature file (.signature). If there is a file named
- `.signature-DISTRIBUTION', it's used instead when posting an
- article in DISTRIBUTION. Set the variable to nil to prevent
- appending the file automatically. If you use an NNTP inews which
- comes with the NNTP package, you may have to set the variable to
- nil.
-
- gnus-use-cross-reference
- Specifies what to do with cross references (Xref: field). If it
- is nil, cross references are ignored. If it is t, articles in
- subscribed newsgroups are only marked as read. Otherwise, if it
- is not nil nor t, articles in all newsgroups are marked as read.
-
- gnus-use-followup-to
- Specifies what to do with followup-to: field. If it is nil, its
- value is ignored. If it is non-nil, its value is used as followup
- newsgroups. Especially, if it is t and field value is `poster',
- your confirmation is required.
-
- gnus-author-copy
- Specifies a file name to save a copy of article you posted using
- FCC: field. If the first character of the value is `|', the
- contents of the article is piped out to a program specified by the
- rest of the value. The variable is initialized from the
- AUTHORCOPY environment variable.
-
- gnus-author-copy-saver
- Specifies a function to save an author copy. The function is
- called with a file name. The default function `rmail-output'
- saves in Unix mail format.
-
- gnus-kill-file-name
- Use specified file name as a KILL file (default to `KILL').
-
- gnus-novice-user
- Non-nil means that you are a novice to USENET. If non-nil,
- verbose messages may be displayed or your confirmations may be
- required.
-
- gnus-interactive-post
- Non-nil means that newsgroup, subject and distribution are asked
- for interactively when posting a new article.
-
- gnus-use-full-window
- Non-nil means to take up the entire screen of Emacs.
-
- gnus-window-configuration
- Specifies the configuration of Group, Summary, and Article
- windows. It is a list of (ACTION (G S A)), where G, S, and A are
- the relative height of Group, Summary, and Article windows,
- respectively. ACTION is `summary', `newsgroups', or `article'.
-
- gnus-subscribe-newsgroup-method
- Specifies a function called with a newsgroup name when new
- newsgroup is found. The default definition adds new newsgroup at
- the beginning of other newsgroups.
-
- And more and more. Please refer to texinfo documentation.
-
-Various hooks for customization:
- gnus-group-mode-hook
- Entry to this mode calls the value with no arguments, if that
- value is non-nil. This hook is called before GNUS is connected to
- the NNTP server. So, you can change or define the NNTP server in
- this hook.
-
- gnus-startup-hook
- Called with no arguments after the NNTP server is selected. It is
- possible to change the behavior of GNUS or initialize the
- variables according to the selected NNTP server.
-
- gnus-group-prepare-hook
- Called with no arguments after a newsgroup list is created in the
- Newsgroup buffer, if that value is non-nil.
-
- gnus-save-newsrc-hook
- Called with no arguments when saving newsrc file if that value is
- non-nil.
-
- gnus-prepare-article-hook
- Called with no arguments after preparing message body, but before
- preparing header fields which is automatically generated if that
- value is non-nil. The default hook (gnus-inews-insert-signature)
- inserts a signature file.
-
- gnus-inews-article-hook
- Called with no arguments when posting an article if that value is
- non-nil. This hook is called just before posting an article. The
- default hook does FCC (save an article to the specified file).
-
- gnus-suspend-gnus-hook
- Called with no arguments when suspending (not exiting) GNUS, if
- that value is non-nil.
-
- gnus-exit-gnus-hook
- Called with no arguments when exiting (not suspending) GNUS, if
- that value is non-nil."

- gnus-summary-mode-hook
- Entry to this mode calls the value with no arguments, if that
- value is non-nil.
-
- gnus-select-group-hook
- Called with no arguments when newsgroup is selected, if that value
- is non-nil. It is possible to sort subjects in this hook. See the
- documentation of this variable for more information.
-
- gnus-summary-prepare-hook
- Called with no arguments after a summary list is created in the
- Summary buffer, if that value is non-nil. If you'd like to modify
- the buffer, you can use this hook.
-
- gnus-select-article-hook
- Called with no arguments when an article is selected, if that
- value is non-nil. See the documentation of this variable for more
- information.
-
- gnus-select-digest-hook
- Called with no arguments when reading digest messages using Rmail,
- if that value is non-nil. This hook can be used to modify an
- article so that Rmail can work with it. See the documentation of
- the variable for more information.
-
- gnus-rmail-digest-hook
- Called with no arguments when reading digest messages using Rmail,
- if that value is non-nil. This hook is intended to customize Rmail
- mode.
-
- gnus-apply-kill-hook
- Called with no arguments when a newsgroup is selected and the
- Summary buffer is prepared. This hook is intended to apply a KILL
- file to the selected newsgroup. The format of KILL file is
- completely different from that of version 3.8. You have to rewrite
- them in the new format. See the documentation of Kill file mode
- for more information.
-
- gnus-mark-article-hook
- Called with no arguments when an article is selected at the first
- time. The hook is intended to mark an article as read (or unread)
- automatically when it is selected. See the documentation of the
- variable for more information.
-
- gnus-exit-group-hook
- Called with no arguments when exiting the current newsgroup, if
- that value is non-nil. If your machine is so slow that exiting
- from Summary mode takes very long time, inhibit marking articles
- as read using cross-references by setting the variable
- gnus-use-cross-reference to nil in this hook."

-\\[gnus-kill-file-kill-by-author] Insert KILL command for current author.
-\\[gnus-kill-file-apply-buffer] Apply current buffer to selected newsgroup.

-
- A KILL file contains Lisp expressions to be applied to a selected
-newsgroup. The purpose is to mark articles as read on the basis of
-some set of regexps. A global KILL file is applied to every newsgroup,
-and a local KILL file is applied to a specified newsgroup. Since a
-global KILL file is applied to every newsgroup, for better performance
-use a local one.
-
- A KILL file can contain any kind of Emacs Lisp expressions expected
-to be evaluated in the Summary buffer. Writing Lisp programs for this
-purpose is not so easy because the internal working of GNUS must be
-well-known. For this reason, GNUS provides a general function which
-does this easily for non-Lisp programmers.
-
- The `gnus-kill' function executes commands available in Summary Mode
-by their key sequences. `gnus-kill' should be called with FIELD,
-REGEXP and optional COMMAND and ALL. FIELD is a string representing
-the header field or an empty string. If FIELD is an empty string, the
-entire article body is searched for. REGEXP is a string which is
-compared with FIELD value. COMMAND is a string representing a valid
-key sequence in Summary mode or Lisp expression. COMMAND defaults to
-\(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is
-executed in the Summary buffer. If the second optional argument ALL
-is non-nil, the COMMAND is applied to articles which are already
-marked as read or unread. Articles which are marked are skipped over
-by default.
-
- For example, if you want to mark articles of which subjects contain
-the string `AI' as read, a possible KILL file may look like:
-
- (gnus-kill \"Subject\" \"AI\")
-
- If you want to mark articles with `D' instead of `X', you can use
-the following expression:
-
- (gnus-kill \"Subject\" \"AI\" \"d\")
-
-\(Here we assume the command `gnus-summary-mark-as-read-forward' is
-assigned to `d' in Summary Mode.)
-
- It is possible to delete unnecessary headers which are marked with

+;;; Commentary:
+
+;; These macros may look very much like the ones in GNUS 4.1. They
+;; are, in a way, but you should note that the indices they use have
+;; been changed from the internal GNUS format to the NOV format. Makes
+;; it possible to read headers from XOVER much faster.
+;;
+;; The format of a header is now:
+;; [number subject from date id references chars lines xref]
+;;
+;; (That last entry is defined as "misc" in the NOV format, but Gnus
+;; uses it for xrefs.)

;;; Commentary:
-;; This implementation is tested on both 1.2a and 1.5 version of the
-;; NNTP package.
-
-;; Troubleshooting of NNTP
-;;
-;; (1) Select routine may signal an error or fall into infinite loop
-;; while waiting for the server response. In this case, you'd better
-;; not use byte-compiled codes but original source. If you still have
-;; a problems with it, set the variable `nntp-buggy-select' to t.
-;;
-;; (2) Emacs may hang up while retrieving headers since too many
-;; requests have been sent to the NNTP server without reading their
-;; replies. In this case, reduce the number of the requests sent to
-;; the server at one time by setting the variable
-;; `nntp-maximum-request' to a lower value.
-;;
-;; (3) If the TCP/IP stream (open-network-stream) is not supported by
-;; emacs, compile and install `tcp.el' and `tcp.c' which is an
-;; emulation program of the stream. If you modified `tcp.c' for your
-;; system, please send me the diffs. I'll include some of them in the
-;; future releases.
