65 "*Non-nil means that Gnus will try to build threads by grabbing old headers.
66 If an unread article in the group refers to an older, already read (or
67 just marked as read) article, the old article will not normally be
68 displayed in the Summary buffer. If this variable is t, Gnus
69 will attempt to grab the headers to the old articles, and thereby
70 build complete threads. If it has the value `some', only enough
71 headers to connect otherwise loose threads will be displayed. This
72 variable can also be a number. In that case, no more than that number
73 of old headers will be fetched. If it has the value `invisible', all
74 old headers will be fetched, but none will be displayed.
76 The server has to support NOV for any of this to work."

87 If t, fetch all the available old headers."
93 "*nil means that Gnus won't gather loose threads.
94 If the root of a thread has expired or been read in a previous
95 session, the information necessary to build a complete thread has been
96 lost. Instead of having many small sub-threads from this original thread
97 scattered all over the summary buffer, Gnus can gather them.
99 If non-nil, Gnus will try to gather all loose sub-threads from an
100 original thread into one large thread.
102 If this variable is non-nil, it should be one of `none', `adopt',
103 `dummy' or `empty'.
105 If this variable is `none', Gnus will not make a false root, but just
106 present the sub-threads after another.

128 "*A regexp to match subjects to be excluded from loose thread gathering.
129 As loose thread gathering is done on subjects only, that means that
130 there can be many false gatherings performed. By rooting out certain
131 common subjects, gathering might become saner."
136 "*Maximum length of subject comparisons when gathering loose threads.
137 Use nil to compare full subjects. Setting this variable to a low
138 number will help gather threads that have been corrupted by
139 newsreaders chopping off subject lines, but it might also mean that
140 unrelated articles that have subject that happen to begin with the
141 same few characters will be incorrectly gathered.
143 If this variable is `fuzzy', Gnus will use a fuzzy algorithm when
144 comparing subjects."
151 "List of functions taking a string argument that simplify subjects.
152 The functions are applied recursively.
154 Useful functions to put in this list include:

323 the first unseen article), `unseen-or-unread' (place point on the subject

341 newsgroup will be selected without any confirmation, and if it is
342 `almost-quietly', the next group will be selected without any
343 confirmation if you are located on the last article in the group.

1404 "A list of variables that have separate values in different newsgroups.
1405 A list of newsgroup (summary buffer) local variables, or cons of
1406 variables and their default expressions to be evalled (when the default
1407 values are not nil), that should be made global while the summary buffer
1408 is active.
1410 Note: The default expressions will be evaluated (using function `eval')
1411 before assignment to the local variable rather than just assigned to it.
1412 If the default expression is the symbol `global', that symbol will not
1413 be evaluated but the global value of the local variable will be used
1414 instead.
1416 These variables can be used to set variables in the group parameters
1417 while still allowing them to affect operations done in other buffers.
1418 For example:
1420 \(setq gnus-newsgroup-variables

1432 ;; following files. Right now, these definitions have been
1433 ;; compiled but not defined (evaluated). We could either do a
