-# This example is complete with exceptions for less normal colour

-# colour temperature, nor use of temporarly linear RGB curves,
-# sigmoid correction, or free function modifier, work on individual
-# subpixels in CIE xyY colour space. Neither does it # support multiple
-# screens, this is normally not an issue because Xinerama is normally
-# used to put all monitors on the same screen; # nor does it parse
-# options other than -r from ad-hoc settigns, or use monitor identifiation.
+# This example covers most of what Blueshift offers. For a complete
+# coverage of Blueshift complement this example with:
+#   backlight, crtc-detection, crtc-searching, logarithmic,
+#   stored-settings, modes, textconf
+# However the are features that are only covered by the info manual:
+#   Methods for calculating correlated colour temperature
