+      (description
+       "Dongle(동글) is a rounded sans-serif typeface for display.  It is a
+modular Hangeul with the de-square frame, creating a playful and rhythmic
+movement.  The name, Dongle comes from a Korean onomatopoeia, meaning 'rounded
+or curved shape (with adorable impression)’.
+
+Dongle was originally designed as a 'Jamo (consonant and vowel in Hangeul)
+typing module' for the author's student project.  Later it revised into
+‘syllabic module’ to be released to the public.  As the character size varies
+according to the syllable structure, Dongle typeface is much smaller compared
+to other square frame Korean typefaces.  Therefore, it is better to adjust the
+font size visually to your liking, rather than relying on the point size of
+the editing program.
+
+It is designed especially for Hangeul typography, but it also includes Latin
+alphabet as a part of KS X 1001.  This typeface has a light, regular, and bold
+weight.")
