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

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

129 "*A regexp to match subjects to be excluded from loose thread gathering.
130 As loose thread gathering is done on subjects only, that means that
131 there can be many false gatherings performed. By rooting out certain
132 common subjects, gathering might become saner."
137 "*Maximum length of subject comparisons when gathering loose threads.
138 Use nil to compare full subjects. Setting this variable to a low
139 number will help gather threads that have been corrupted by
140 newsreaders chopping off subject lines, but it might also mean that
141 unrelated articles that have subject that happen to begin with the
142 same few characters will be incorrectly gathered.
144 If this variable is `fuzzy', Gnus will use a fuzzy algorithm when
145 comparing subjects."

1431 "A list of variables that have separate values in different newsgroups.
1432 A list of newsgroup (summary buffer) local variables, or cons of
1433 variables and their default expressions to be evalled (when the default
1434 values are not nil), that should be made global while the summary buffer
1435 is active.
1437 Note: The default expressions will be evaluated (using function `eval')
1438 before assignment to the local variable rather than just assigned to it.
1439 If the default expression is the symbol `global', that symbol will not
1440 be evaluated but the global value of the local variable will be used
1441 instead.
1443 These variables can be used to set variables in the group parameters
1444 while still allowing them to affect operations done in other buffers.
1445 For example:
1447 \(setq gnus-newsgroup-variables

1459 ;; following files. Right now, these definitions have been
1460 ;; compiled but not defined (evaluated). We could either do a
