+     "This package provides the PlayFairDisplay family of fonts, designed by
+Claus Eggers Sorensen, for use with LaTeX, pdfLaTeX, XeLaTeX and LuaLaTeX.
+PlayFairDisplay is well suited for titling and headlines.  It has an extra
+large x-height and short descenders.  It can be set with no leading if space
+is tight, for instance in news headlines, or for stylistic effect in titles.
+Capitals are extra short, and only very slightly heavier than the lowercase
+characters.  This helps achieve a more even typographical colour when
+typesetting proper nouns and initialisms.")
