-Note that the =load-theme= here is slightly different than the one in the
-section right above, because it does not enable the theme directly (the
-subsequent =enable-theme= does that when needed).
+A modified version of the above technique was contributed by André
+Alexandre Gomes. If you set =calendar-latitude= and =calendar-longitude=
+(defined in the built-in =solar.el= library) in your =init.el=, you can
+automatically switch between both themes at sunrise and sunset. Note
+that /those calendar variables need to be set before loading the themes/.

+For the sake of completeness, the =load-theme= call in these snippets is
+slightly different than the one in the section right above, because it
+does not enable the theme directly: the subsequent =enable-theme= does
+that when needed.
