+    (description
+     "Cormorant is an extravagant display serif typeface inspired by
+the Garamond heritage.  The design goal of Cormorant was to distill
+the aesthetic essence of Garamond, unfetter it from the limitations of
+metal printing, and allow it to bloom into its natural refined form at
+high definition.  Cormorant is characterized by scandalously small
+counters, razor-sharp serifs, dangerously smooth curves, and
+flamboyantly tall accents.  While many implementations of Garamond at
+small optical sizes already exist, Cormorant aims for the sparsely
+populated niche of display-size counterparts that exploit the high
+resolution of contemporary screens and print media to the fullest.")
