+RATIONALE
+	Few users have calibration hardware, and CRT monitors can
+	be sufficiently calibrated manually without them. However,
+	before crt-calibrator the best way to calibrator CRT monitors
+	was to have specialised test images, with colour bars and
+	samples. But this requires expertise, the common user will
+	know how to contruct these images or the best procedure for
+	applying the corrections. And it is tedious if you do not
+	find any interactive tool for change changing the settings.
+	The alternative why was to use test pictures that relied on
+	you deciding what looked most realistic rather than the
+	image itself telling you. But that's not all, to my knowledge,
+	this is actually the first program that runs outside a
+	display server.
