+=head2 bugmail_recipients
+
+This allows you to modify the list of users who are going to be receiving
+a particular bugmail. It also allows you to specify why they are receiving
+the bugmail.
+
+Users' bugmail preferences will be applied to any users that you add
+to the list. (So, for example, if you add somebody as though they were
+a CC on the bug, and their preferences state that they don't get email
+when they are a CC, they won't get email.)
+
+This hook is called before watchers or globalwatchers are added to the
+recipient list.
+
+Params:
+
+=over
+
+=item C<recipients>
+
+This is a hashref. The keys are numeric user ids from the C<profiles>
+table in the database, for each user who should be receiving this bugmail.
+The values are hashrefs. The keys in I<these> hashrefs correspond to
+the "relationship" that the user has to the bug they're being emailed
+about, and the value should always be C<1>. The "relationships"
+are described by the various C<REL_> constants in L<Bugzilla::Constants>.
+
+Here's an example of adding userid C<123> to the recipient list
+as though he were on the CC list:
+
+ $recipients->{123}->{+REL_CC} = 1
+
+(We use C<+> in front of C<REL_CC> so that Perl interprets it as a constant
+instead of as a string.)
