+emphasis on internationalization.  Pango can be used anywhere that text layout
+is needed, but using Pango in conjunction with Cairo and/or Gtk2 provides a
+complete solution with high quality text handling and graphics rendering.
+
+Dynamically loaded modules handle text layout for particular combinations of
+script and font backend.  Pango provides a wide selection of modules, including
+modules for Hebrew, Arabic, Hangul, Thai, and a number of Indic scripts.
+Virtually all of the world's major scripts are supported.
+
+In addition to the low level layout rendering routines, Pango includes
+@code{Pango::Layout}, a high level driver for laying out entire blocks of text,
+and routines to assist in editing internationalized text.")
