+HarfBuzz functions and constants
+--------------------------------
+
+As of version 2.0.18, SDL2_ttf makes use of the HarfBuzz library for advanced
+text rendering and shaping unless explicitly compiled without it. As a
+consequence, some specific SDL2_ttf functions require HarfBuzz constants and
+macros for input.
+
+To make these easier to use, the ``sdlttf`` module defines and implements the
+constants and macro functions necessary to make full use of the SDL2_ttf
+library.
