+This directory contains various graphics hacks. These are independent from
+the xscreensaver program (in the ../driver/ directory) but some of them use
+the utility functions found in the ../utils/ directory.
+
+If you have compilation problems, check the parameters in ../config.h.
+
+The file xlock.h makes it really easy to turn `xlock' modules into standalone
+programs that can be used with xscreensaver; check it out.
