+ * This fairly simple test program dumps output in a similar format to the
+ * "xrandr" tool everyone knows & loves.  It's necessarily slightly different
+ * since the kernel separates outputs into encoder and connector structures,
+ * each with their own unique ID.  The program also allows test testing of the
+ * memory management and mode setting APIs by allowing the user to specify a
+ * connector and mode to use for mode setting.  If all works as expected, a
+ * blue background should be painted on the monitor attached to the specified
+ * connector after the selected mode is set.
+ *
+ * TODO: use cairo to write the mode info on the selected output once
+ *       the mode has been programmed, along with possible test patterns.
