+# Setup hook that installs specified desktop items.
+#
+# Example usage in a derivation:
+#
+#   { …, makeDesktopItem, copyDesktopItems, … }:
+#
+#   let desktopItem = makeDesktopItem { … }; in
+#   stdenv.mkDerivation {
+#     …
+#     nativeBuildInputs = [ copyDesktopItems ];
+#
+#     desktopItems =  [ desktopItem ];
+#     …
+#   }
+#
+# This hook will copy files which are either given by full path
+# or all '*.desktop' files placed inside the 'share/applications'
+# folder of each `desktopItems` argument.
