+     "The design of Didot's 1805 Greek typeface was influenced by the
+neoclassical ideals of the late 18th century.  The font was brought to Greece
+at the time of the 1821 Greek Revolution, by Didot's son, and was very widely
+used.  The font supports the Greek alphabet, and is accompanied by a matching
+Latin alphabet based on Zapf's Palatino.  LaTeX support is provided, using the
+OT1, T1, TS1, and LGR encodings.")
