+Notice:
+  This is the first release of a jumptable version of the libraries
+  'pbm', 'pgm', 'ppm', 'pnm' (from the pbmplus package), 'rle' (from 
+  the utah raster toolkit), 'jpeg' (from the independent jpeg group), 
+  and 'tiff' (taken from the XV package).
+  Jumptable and static libs and the shared image are supplied.
+  The package further contains only that sources that are needed to 
+  rebuild the libraries. 
+  Original sources are available in the packages mentioned above.
+
+Jumplib info:
+  The jumplib looks like a big file, but it contains a hole,
+  so actually it is quite a bit smaller. The savings on the binaries
+  from the pbmplus package is more than 1 MB, and on the binaries
+  for the Utah Raster Toolkit too. Programs using the 'jpeg' software
+  are about 50kB smaller when linked with this lib. For a good example
+  get 'xv'.
+
+Warning: 
+  The graphics jumptable lib is in a testing phase. 
+  every binary I've tested worked ok so far.
