-Basically, the most important class is L{Instance}, which is used
-to create a libvlc instance. From this instance, you then create
-L{MediaPlayer} and L{MediaListPlayer} instances.
-
-Alternatively, you may create instances of the L{MediaPlayer} and
-L{MediaListPlayer} class directly and an instance of L{Instance}
-will be implicitly created. The latter can be obtained using the
-C{get_instance} method of L{MediaPlayer} and L{MediaListPlayer}.

- Also while LibVLC is active, the wait() function shall not be called, and
