+=head2 listsubjects
+
+ ($count, $results) = &listsubjects($subject, $n, $offset);
+
+Finds the subjects that begin with C<$subject> in the bibliosubject
+table of the Koha database.
+
+C<&listsubjects> returns a two-element array. C<$results> is a
+reference-to-array, in which each element is a reference-to-hash
+giving information about the given subject. C<$count> is the number of
+elements in C<@{$results}>.
+
+Probably the only interesting field in C<$results->[$i]> is
+C<subject>, the subject in question.
+
+C<&listsubject> returns up to C<$n> items, starting at C<$offset>. If
+C<$n> is 0, it will return all matching subjects.
