+    (description
+     "power-profiles-daemon offers to modify system behaviour based upon
+user-selected power profiles.  There are 3 different power profiles, a
+\"balanced\" default mode, a \"power-saver\" mode, as well as a
+\"performance\" mode.  The first 2 of those are available on every system.
+The \"performance\" mode is only available on select systems and is
+implemented by different \"drivers\" based on the system or systems it
+targets.  In addition to those 2 or 3 modes (depending on the system),
+\"actions\" can be hooked up to change the behaviour of a particular device.
+For example, this can be used to disable the fast-charging for some USB
+devices when in power-saver mode.")
