+	  Szip is an implementation of the extended-Rice lossless
+	  compression algorithm.
+
+	  The Consultative Committee on Space Data Systems (CCSDS) has
+	  adopted the extended-Rice algorithm for international
+	  standards for space applications[1,6,7]. Szip is reported to
+	  provide fast and effective compression, specifically for the
+	  EOS data generated by the NASA Earth Observatory System
+	  (EOS)[1].  It was originally developed at University of New
+	  Mexico (UNM) and integrated with HDF4 by UNM researchers and
+	  developers.
