If the name of a group is matched by REGEXP, the corresponding scorefiles
will be used for that group.
The first match found is used, subsequent matching entries are ignored (to
-use multiple matches, see gnus-score-file-multiple-match-alist).
+use multiple matches, see `gnus-score-file-multiple-match-alist').
These score files are loaded in addition to any files returned by
-gnus-score-find-score-files-function (which see)."
+`gnus-score-find-score-files-function'."
:group 'gnus-score-files
:type '(repeat (cons regexp (repeat file))))
will be used for that group.
If multiple REGEXPs match a group, the score files corresponding to each
match will be used (for only one match to be used, see
-gnus-score-file-single-match-alist).
+`gnus-score-file-single-match-alist').
These score files are loaded in addition to any files returned by
-gnus-score-find-score-files-function (which see)."

Predefined values are:
-gnus-score-find-single: Only apply the group's own score file.
-gnus-score-find-hierarchical: Also apply score files from parent groups.
-gnus-score-find-bnews: Apply score files whose names matches.
+`gnus-score-find-single': Only apply the group's own score file.
+`gnus-score-find-hierarchical': Also apply score files from parent groups.
+`gnus-score-find-bnews': Apply score files whose names matches.
See the documentation to these functions for more information.
This variable can also be a list of functions to be called. Each
-function should either return a list of score files, or a list of
-score alists.
+function is given the group name as argument and should either return
