+      Pango is a library for laying out and rendering of text, with an
+      emphasis on internationalization.  Pango can be used anywhere
+      that text layout is needed, though most of the work on Pango so
+      far has been done in the context of the GTK widget toolkit.
+      Pango forms the core of text and font handling for GTK.
