function activate()
    create_dialog()
end

function deactivate()
    close()
    vlc.deactivate()
end

-- create_dialog() : creates the dialog containing the initial widgets
function create_dialog()
    dlg = vlc.dialog(descriptor().title)
    dlg:add_label("<b>Hello World: VLC Lua scripts and extensions</b>")
end
