"""This module provides bindings for the LibVLC public API, see
U{http://wiki.videolan.org/LibVLC}.

You can find the documentation and a README file with some examples
at U{http://www.advene.org/download/python-ctypes/}.

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}.
