47 "Your `.newsrc' file.
48 `.newsrc-SERVER' will be used instead if that exists."
53 "Control use of version numbers for backups of `gnus-startup-file'.
54 This variable takes the same values as the `version-control'
55 variable."
63 "Whether to write the startup file contents to a buffer then save
64 the buffer or write directly to the file. The buffer is faster
65 because all of the contents are written at once. The direct write
66 uses considerably less memory."
73 "Your Gnus Emacs-Lisp startup file name.
74 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
84 "The site-wide Gnus Emacs-Lisp startup file name, or nil if none.
85 If a file with the `.el' or `.elc' suffixes exists, it will be read instead."
90 "*Non-nil means that Gnus will use a dribble file to store user updates.
91 If Emacs should crash without saving the .newsrc files, complete
92 information can be restored from the dribble file."
97 "*The directory where dribble files will be saved.
98 If this variable is nil, the directory where the .newsrc files are
99 saved will be used."
104 "*Non-nil means that Gnus will run `gnus-find-new-newsgroups' at startup.
105 This normally finds new newsgroups by comparing the active groups the
106 servers have already reported with those Gnus already knows, either alive
107 or killed.
109 When any of the following are true, `gnus-find-new-newsgroups' will instead
110 ask the servers (primary, secondary, and archive servers) to list new
111 groups since the last time it checked:
112 1. This variable is `ask-server'.
113 2. This variable is a list of select methods (see below).
114 3. `gnus-read-active-file' is nil or `some'.
115 4. A prefix argument is given to `gnus-find-new-newsgroups' interactively.
117 Thus, if this variable is `ask-server' or a list of select methods or
118 `gnus-read-active-file' is nil or `some', then the killed list is no
119 longer necessary, so you could safely set `gnus-save-killed-list' to nil.
121 This variable can be a list of select methods which Gnus will query with
122 the `ask-server' method in addition to the primary, secondary, and archive
123 servers.
125 Eg.
126 (setq gnus-check-new-newsgroups
129 If this variable is nil, then you have to tell Gnus explicitly to
141 "*Non-nil means that Gnus will check and remove bogus newsgroup at startup.
142 If this variable is nil, then you have to tell Gnus explicitly to
148 "*Non-nil means that Gnus will read the entire active file at startup.
149 If this variable is nil, Gnus will only know about the groups in your
150 `.newsrc' file.
152 If this variable is `some', Gnus will try to only read the relevant
153 parts of the active file from the server. Not all servers support
154 this, and it might be quite slow with other servers, but this should
155 generally be faster than both the t and nil value.
157 If you set this variable to nil or `some', you probably still want to
158 be told about new newsgroups that arrive. To do that, set
159 `gnus-check-new-newsgroups' to `ask-server'. This may not work
160 properly with all servers."
170 "Groups with levels less than or equal to this variable are unsubscribed.
172 Groups with levels less than `gnus-level-subscribed', which
173 should be less than this variable, are subscribed. Groups with
174 levels from `gnus-level-subscribed' (exclusive) upto this
175 variable (inclusive) are unsubscribed. See also
176 `gnus-level-zombie', `gnus-level-killed' and the Info node `(gnus)Group
186 "*New subscribed groups will be subscribed at this level."
191 "*New unsubscribed groups will be unsubscribed at this level."
196 "*Groups higher than this level won't be activated on startup.
197 Setting this variable to something low might save lots of time when
198 you have many groups that you aren't interested in."
203 "*If nil, Gnus will not check foreign newsgroups at startup.
204 If it is non-nil, it should be a number between one and nine. Foreign
205 newsgroups that have a level lower or equal to this number will be
206 activated on startup. For instance, if you want to active all
207 subscribed newsgroups, but not the rest, you'd set this variable to
208 `gnus-level-subscribed'.
210 If you subscribe to lots of newsgroups from different servers, startup
211 might take a while. By setting this variable to nil, you'll save time,
212 but you won't be told how many unread articles there are in the
213 groups."

220 Gnus always reads its own startup file, which is called
222 be readily understood by other newsreaders. If you don't plan on
223 using other newsreaders, set this variable to nil to save some time on
224 entry."
230 "*Non-nil means that Gnus will save the `.newsrc' file.
231 Gnus always saves its own startup file, which is called
233 be readily understood by other newsreaders. If you don't plan on
234 using other newsreaders, set this variable to nil to save some time on
235 exit."
240 "*If non-nil, save the list of killed groups to the startup file.
241 If you set this variable to nil, you'll save both time (when starting
242 and quitting) and space (both memory and disk), but it will also mean
243 that Gnus has no record of which groups are new and which are old, so
244 the automatic new newsgroups subscription methods become meaningless.
246 You should always set `gnus-check-new-newsgroups' to `ask-server' or
247 nil if you set this variable to nil.
249 This variable can also be a regexp. In that case, all groups that do
250 not match this regexp will be removed before saving the list."

267 Any lines in the active file matching this regular expression are
268 removed from the newsgroup list before anything else is done to it,
269 thus making them effectively non-existent."
274 "*Function(s) called with a group name when new group is detected.
275 A few pre-made functions are supplied: `gnus-subscribe-randomly'
276 inserts new groups at the beginning of the list of groups;
277 `gnus-subscribe-alphabetically' inserts new groups in strict

331 subscribe to all newsgroups in the hierarchy and `s' will skip this
332 hierarchy in its entirety."
