+Notice:
+  This is a package of the programs from the Utah Raster Toolkit. These 
+  binaries are linked with my graphics jumptable lib, so you'll need the 
+  package libgr01.TZ as well to use the programs. Source code and manuals of
+  the programs are in package urt-31a.TZ
+
+Warning: 
+  The graphics jumptable lib is in a testing phase. The binaries work
+  correctly as far as I can tell. You'll need X11v2.1 for the X11-dependent
+  binaries.
