+    (description
+     "This package contains the OpenType Textura font Missaali and a style
+file for using it with XeLaTeX.  Textura is a typeface based on the
+@emph{textus quadratus} form of the @emph{textualis formata} that late
+medieval scribes used for the most valuable manuscripts.  The font Missaali is
+based on Textura that German printer Bartholomew Ghotan used for printing
+missals and psalters in the 1480s.
+
+This font has two intended use cases: as a Gothic display font; and for
+emulating late-medieval manuscripts.  In addition to the basic Textura
+letters, the font contains a large number of abbreviation sigla as well as
+a set of Lombardic initials.  As modern typesetting algorithms are not
+intended for creating 15th century style layout, the package contains
+a XeLaTeX style file that makes it easier to achieve the classic incunabula
+look.")
