+Summary: FPACK FITS image compression and decompression utilites
+Group: Applications/Engineering
+
+%description -n fpack
+fpack optimally compresses FITS format images and funpack restores them
+to the original state.
+
+* Integer format images are losslessly compressed using the Rice
+compression algorithm.
+    * typically 30% better compression than GZIP
+    * about 3 times faster compression speed than GZIP
+    * about the same uncompression speed as GUNZIP 
+
+* Floating-point format images are compressed with a lossy algorithm
+    * truncates the image pixel noise by a user-specified amount to
+      produce much higher compression than by lossless techniques
+    * the precision of scientific measurements in the compressed image
+      (relative to those in the original image) depends on the selected
+       amount of compression
