26 ;; How to Install GNUS:
27 ;; (0) First of all, remove GNUS related OLD *.elc files (at least
29 ;; (1) Unshar gnus.el, gnuspost.el, gnusmail.el, gnusmisc.el, and
31 ;; (2) byte-compile-file nntp.el, gnus.el, gnuspost.el, gnusmail.el,
32 ;; and gnusmisc.el. If you have a local news spool,
33 ;; byte-compile-file nnspool.el, too.
34 ;; (3) Define three environment variables in .login file as follows:
36 ;; setenv NNTPSERVER flab
37 ;; setenv DOMAINNAME "stars.flab.Fujitsu.CO.JP"
38 ;; setenv ORGANIZATION "Fujitsu Laboratories Ltd., Kawasaki, Japan."
40 ;; Or instead, define lisp variables in your .emacs, site-init.el,
41 ;; or default.el as follows:
43 ;; (setq gnus-nntp-server "flab")
44 ;; (setq gnus-local-domain "stars.flab.Fujitsu.CO.JP")
45 ;; (setq gnus-local-organization "Fujitsu Laboratories Ltd., ...")
47 ;; If the function (system-name) returns the full internet name,
48 ;; you don't have to define the domain.
50 ;; (4) You may have to define NNTP service name as number 119.
52 ;; (setq gnus-nntp-service 119)
54 ;; Or, if you'd like to use a local news spool directly in stead
55 ;; of NNTP, install nnspool.el and set the variable to nil as
58 ;; (setq gnus-nntp-service nil)
60 ;; (5) If you'd like to use the GENERICFROM feature like the Bnews,
61 ;; define the variable as follows:
63 ;; (setq gnus-use-generic-from t)
65 ;; (6) Define autoload entries in .emacs file as follows:
67 ;; (autoload 'gnus "gnus" "Read network news." t)
68 ;; (autoload 'gnus-post-news "gnuspost" "Post a news." t)
70 ;; (7) Read nntp.el if you have problems with NNTP or kanji handling.
72 ;; (8) Install mhspool.el, tcp.el, and tcp.c if it is necessary.
74 ;; mhspool.el is a package for reading articles or mail in your
75 ;; private directory using GNUS.
77 ;; tcp.el and tcp.c are necessary if and only if your Emacs does
78 ;; not have the function `open-network-stream' which is used for
79 ;; communicating with NNTP server inside Emacs.
81 ;; (9) Install an Info file generated from the texinfo manual gnus.texinfo.
83 ;; If you are not allowed to create the Info file to the standard
84 ;; Info-directory, create it in your private directory and set the
85 ;; variable gnus-info-directory to that directory.
87 ;; For getting more information about GNUS, consult USENET newsgorup
91 ;; (1) Incremental update of active info.
92 ;; (2) Asynchronous transmission of large messages.

1015 The name of the host running NNTP server is asked for if no default
1016 host is specified. It is also possible to choose another NNTP server
1017 even when the default server is defined by giving a prefix argument to
1018 the command `\\[gnus]'.
1020 If an NNTP server is preceded by a colon such as `:Mail', the user's
1021 private directory `~/Mail' is used as a news spool. This makes it
1022 possible to read mail stored in MH folders or articles saved by GNUS.
1023 File names of mail or articles must consist of only numeric
1024 characters. Otherwise, they are ignored.
1026 If there is a file named `~/.newsrc-SERVER', it is used as the
1027 startup file instead of standard one when talking to SERVER. It is
1028 possible to talk to many hosts by using different startup files for
1031 Option `-n' of the options line in the startup file is recognized
1032 properly the same as the Bnews system. For example, if the options
1033 line is `options -n !talk talk.rumors', newsgroups under the `talk'
1034 hierarchy except for `talk.rumors' are ignored while checking new
1037 If there is a file named `~/.signature-DISTRIBUTION', it is used as
1038 signature file instead of standard one when posting a news in
1041 If an Info file generated from `gnus.texinfo' is installed, you can
1042 read an appropriate Info node of the Info file according to the
1043 current major mode of GNUS by \\[gnus-info-find-node].
1045 The variable `gnus-version', `nntp-version', `nnspool-version', and
1046 `mhspool-version' have the version numbers of this version of gnus.el,
1047 nntp.el, nnspool.el, and mhspoo.el, respectively.
1049 User customizable variables:
1051 Specifies the name of the host running the NNTP server. If its
1052 value is a string such as `:DIRECTORY', the user's private
1053 DIRECTORY is used as a news spool. The variable is initialized
1054 from the NNTPSERVER environment variable.
1057 Specifies a NNTP service name. It is usually \"nntp\" or 119.
1058 Nil forces GNUS to use a local news spool if the variable
1059 `gnus-nntp-server' is set to the local host name.
1062 Specifies a startup file (.newsrc). If there is a file named
1063 `.newsrc-SERVER', it's used instead when talking to SERVER. I
1064 recommend you to use the server specific file, if you'd like to
1065 talk to many servers. Especially if you'd like to read your
1066 private directory, the name of the file must be
1067 `.newsrc-:DIRECTORY'.
1070 Specifies a signature file (.signature). If there is a file named
1071 `.signature-DISTRIBUTION', it's used instead when posting an
1072 article in DISTRIBUTION. Set the variable to nil to prevent
1073 appending the file automatically. If you use an NNTP inews which
1074 comes with the NNTP package, you may have to set the variable to
1077 gnus-use-cross-reference
1078 Specifies what to do with cross references (Xref: field). If it
1079 is nil, cross references are ignored. If it is t, articles in
1080 subscribed newsgroups are only marked as read. Otherwise, if it
1081 is not nil nor t, articles in all newsgroups are marked as read.
1083 gnus-use-followup-to
1084 Specifies what to do with followup-to: field. If it is nil, its
1085 value is ignored. If it is non-nil, its value is used as followup
1086 newsgroups. Especially, if it is t and field value is `poster',
1087 your confirmation is required.
1090 Specifies a file name to save a copy of article you posted using
1091 FCC: field. If the first character of the value is `|', the
1092 contents of the article is piped out to a program specified by the
1093 rest of the value. The variable is initialized from the
1094 AUTHORCOPY environment variable.
1096 gnus-author-copy-saver
1097 Specifies a function to save an author copy. The function is
1098 called with a file name. The default function `rmail-output'
1099 saves in Unix mail format.
1102 Use specified file name as a KILL file (default to `KILL').
1105 Non-nil means that you are a novice to USENET. If non-nil,
1106 verbose messages may be displayed or your confirmations may be
1109 gnus-interactive-post
1110 Non-nil means that newsgroup, subject and distribution are asked
1111 for interactively when posting a new article.
1113 gnus-use-full-window
1114 Non-nil means to take up the entire screen of Emacs.
1116 gnus-window-configuration
1117 Specifies the configuration of Group, Summary, and Article
1118 windows. It is a list of (ACTION (G S A)), where G, S, and A are
1119 the relative height of Group, Summary, and Article windows,
1120 respectively. ACTION is `summary', `newsgroups', or `article'.
1122 gnus-subscribe-newsgroup-method
1123 Specifies a function called with a newsgroup name when new
1124 newsgroup is found. The default definition adds new newsgroup at
1125 the beginning of other newsgroups.
1127 And more and more. Please refer to texinfo documentation.
1129 Various hooks for customization:
1130 gnus-group-mode-hook
1131 Entry to this mode calls the value with no arguments, if that
1132 value is non-nil. This hook is called before GNUS is connected to
1133 the NNTP server. So, you can change or define the NNTP server in
1137 Called with no arguments after the NNTP server is selected. It is
1138 possible to change the behavior of GNUS or initialize the
1139 variables according to the selected NNTP server.
1141 gnus-group-prepare-hook
1142 Called with no arguments after a newsgroup list is created in the
1143 Newsgroup buffer, if that value is non-nil.
1145 gnus-save-newsrc-hook
1146 Called with no arguments when saving newsrc file if that value is
1149 gnus-prepare-article-hook
1150 Called with no arguments after preparing message body, but before
1151 preparing header fields which is automatically generated if that
1152 value is non-nil. The default hook (gnus-inews-insert-signature)
1153 inserts a signature file.
1155 gnus-inews-article-hook
1156 Called with no arguments when posting an article if that value is
1157 non-nil. This hook is called just before posting an article. The
1158 default hook does FCC (save an article to the specified file).
1160 gnus-suspend-gnus-hook
1161 Called with no arguments when suspending (not exiting) GNUS, if
1162 that value is non-nil.
1165 Called with no arguments when exiting (not suspending) GNUS, if
1166 that value is non-nil."

2044 Various hooks for customization:
2045 gnus-summary-mode-hook
2046 Entry to this mode calls the value with no arguments, if that
2049 gnus-select-group-hook
2050 Called with no arguments when newsgroup is selected, if that value
2051 is non-nil. It is possible to sort subjects in this hook. See the
2052 documentation of this variable for more information.
2054 gnus-summary-prepare-hook
2055 Called with no arguments after a summary list is created in the
2056 Summary buffer, if that value is non-nil. If you'd like to modify
2057 the buffer, you can use this hook.
2059 gnus-select-article-hook
2060 Called with no arguments when an article is selected, if that
2061 value is non-nil. See the documentation of this variable for more
2064 gnus-select-digest-hook
2065 Called with no arguments when reading digest messages using Rmail,
2066 if that value is non-nil. This hook can be used to modify an
2067 article so that Rmail can work with it. See the documentation of
2068 the variable for more information.
2070 gnus-rmail-digest-hook
2071 Called with no arguments when reading digest messages using Rmail,
2072 if that value is non-nil. This hook is intended to customize Rmail
2075 gnus-apply-kill-hook
2076 Called with no arguments when a newsgroup is selected and the
2077 Summary buffer is prepared. This hook is intended to apply a KILL
2078 file to the selected newsgroup. The format of KILL file is
2079 completely different from that of version 3.8. You have to rewrite
2080 them in the new format. See the documentation of Kill file mode
2081 for more information.
2083 gnus-mark-article-hook
2084 Called with no arguments when an article is selected at the first
2085 time. The hook is intended to mark an article as read (or unread)
2086 automatically when it is selected. See the documentation of the
2087 variable for more information.
2089 gnus-exit-group-hook
2090 Called with no arguments when exiting the current newsgroup, if
2091 that value is non-nil. If your machine is so slow that exiting
2092 from Summary mode takes very long time, inhibit marking articles
2093 as read using cross-references by setting the variable
2094 gnus-use-cross-reference to nil in this hook."

4473 A KILL file contains lisp expressions to be applied to a selected
4474 newsgroup. The purpose is to mark articles as read on the basis of
4475 some set of regexps. A global KILL file is applied to every newsgroup,
4476 and a local KILL file is applied to a specified newsgroup. Since a
4477 global KILL file is applied to every newsgroup, for better performance
4480 A KILL file can contain any kind of Emacs lisp expressions expected
4481 to be evaluated in the Summary buffer. Writing lisp programs for this
4482 purpose is not so easy because the internal working of GNUS must be
4483 well-known. For this reason, GNUS provides a general function which
4484 does this easily for non-Lisp programmers.
4486 The `gnus-kill' function executes commands available in Summary Mode
4487 by their key sequences. `gnus-kill' should be called with FIELD,
4488 REGEXP and optional COMMAND and ALL. FIELD is a string representing
4489 the header field or an empty string. If FIELD is an empty string, the
4490 entire article body is searched for. REGEXP is a string which is
4491 compared with FIELD value. COMMAND is a string representing a valid
4492 key sequence in Summary Mode or Lisp expression. COMMAND is default to
4493 '(gnus-summary-mark-as-read nil \"X\"). Make sure that COMMAND is
4494 executed in the Summary buffer. If the second optional argument ALL
4495 is non-nil, the COMMAND is applied to articles which are already
4496 marked as read or unread. Articles which are marked are skipped over
4499 For example, if you want to mark articles of which subjects contain
4500 the string `AI' as read, a possible KILL file may look like:
4502 (gnus-kill \"Subject\" \"AI\")
4504 If you want to mark articles with `D' instead of `X', you can use
4505 the following expression:
4507 (gnus-kill \"Subject\" \"AI\" \"d\")
4509 In this example it is assumed that the command
4510 `gnus-summary-mark-as-read-forward' is assigned to `d' in Summary Mode.
4512 It is possible to delete unnecessary headers which are marked with
4513 `X' in a KILL file as follows:
4515 (gnus-expunge \"X\")
4517 If the Summary buffer is empty after applying KILL files, GNUS will
4518 exit the selected newsgroup normally. If headers which are marked
4519 with `D' are deleted in a KILL file, it is impossible to read articles
4520 which are marked as read in the previous GNUS sessions. Marks other
4521 than `D' should be used for articles which should really be deleted.
