-- Module:Hatnote list --
-- --
-- This module produces and formats lists for use in hatnotes. In particular, --
-- it implements the for-see list, i.e. lists of "For X, see Y" statements, --
-- as used in {{about}}, {{redirect}}, and their variants. Also introduced --
-- are andList & orList helpers for formatting lists with those conjunctions. --

-- the "Y" portion of "For X, see Y" for-see items.
