+    (description "Ginga is a toolkit designed for building viewers for
+scientific image data in Python, visualizing 2D pixel data in numpy arrays.  It
+can view astronomical data such as contained in files based on the
+FITS (Flexible Image Transport System) file format.  It is written and is
+maintained by software engineers at the National Astronomical Observatory of
+Japan (NAOJ), the Space Telescope Science Institute (STScI), and other
+contributing entities.
+
+The Ginga toolkit centers around an image display object which supports zooming
+and panning, color and intensity mapping, a choice of several automatic cut
+levels algorithms and canvases for plotting scalable geometric forms.  In
+addition to this widget, a general purpose \"reference\" FITS viewer is
+provided, based on a plugin framework.  A fairly complete set of standard plugins
+are provided for features that we expect from a modern FITS viewer: panning and
+zooming windows, star catalog access, cuts, star pick/FWHM, thumbnails, etc.")
