+SAOImageDS9 is an astronomical imaging and data visualization application. DS9
+is a stand-alone application which supports FITS images and binary tables,
+multiple frame buffers, region manipulation, and many scale algorithms and
+colormaps.  DS9 supports a consistent set of GUI and functional capabilities,
+as well as advanced features such as 2-D, 3-D and RGB frame buffers, mosaic
+images, tiling, blinking, geometric markers, colormap manipulation, scaling,
+arbitrary zoom, cropping, rotation, pan, and a variety of coordinate systems.
+The GUI for DS9 is user configurable. GUI elements such as the coordinate
+display, panner, magnifier, horizontal and vertical graphs, button bar, and
+color bar can be configured via menus or the command line.
