+
+It is possible to configure Murphy to use GPLv2-licensed libraries. At
+least libdbus is licensed under the GPLv2, and under some circumstances
+PulseAudio client library might also fall under the GPLv2. If Murphy is
+configured to use these GPL-licensed libraries, Murphy must be
+distributed under the restrictions defined in GPLv2 license text.
+
+To prevent mistakes in licensing, Murphy needs to be configured with
+--enable-gpl configuration option in order to use the GPLv2-licensed
+libaries. This is meant as a heads-up for the system integrator to
+double-check the licensing and distribution of possible proprietary
+Murphy plugins.
