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

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

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

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.

1402 "A list of variables that have separate values in different newsgroups.
1403 A list of newsgroup (summary buffer) local variables, or cons of
1404 variables and their default expressions to be evalled (when the default
1405 values are not nil), that should be made global while the summary buffer
1406 is active.
1408 Note: The default expressions will be evaluated (using function `eval')
1409 before assignment to the local variable rather than just assigned to it.
1410 If the default expression is the symbol `global', that symbol will not
1411 be evaluated but the global value of the local variable will be used
1412 instead.
1414 These variables can be used to set variables in the group parameters
1415 while still allowing them to affect operations done in other buffers.
1416 For example:
1418 \(setq gnus-newsgroup-variables

1430 ;; following files. Right now, these definitions have been
1431 ;; compiled but not defined (evaluated). We could either do a
