+     "This package provides Computer Modern Unicode fonts.  Some characters in
+several fonts are copied from Blue Sky Type 1 fonts released by AMS.
+Currently the fonts contain glyphs from Latin, Cyrillic, Greek code sets and
+IPA extensions.  This font set contains 33 fonts.  This archive contains AFM,
+PFB and OTF versions; the OTF version of the Computer Modern Unicode fonts
+works with TeX engines that directly support OpenType features, such as XeTeX
+and LuaTeX.")
