-Pango is a library for layout and rendering of text, with an emphasis
-on internationalization. Pango can be used anywhere that text layout
-is needed; however, most of the work on Pango so far has been done using 
-the GTK+ widget toolkit as a test platform. Pango forms the core of text
-and font handling for GTK+-2.x.

-Summary:        Development environment for %{name}
+Pango is designed to be modular; the core Pango layout engine can be used
+with different font backends.
+
+The integration of Pango with Cairo provides a complete solution with high
+quality text handling and graphics rendering.
