+--1 Tense, Polarity, and Anteriority
+
+-- This module defines the abstract parameters of tense, polarity, and
+-- anteriority, which are used in [Tensed Tensed.html] to generate different
+-- forms of sentences. Together they give 2 x 4 x 4 = 16 sentence forms.
+
+-- These tenses are defined for all languages in the library. More tenses
+-- can be defined in the language extensions, e.g. the "passé simple" of
+-- Romance languages.
