    This plugin allows to interact with \l{http://www.lg.com/us/experience-tvs/smart-tv}{LG Smart Tv's}
    with the \l{http://developer.lgappstv.com/TV_HELP/index.jsp?topic=%2Flge.tvsdk.references.book%2Fhtml%2FUDAP%2FUDAP%2FLG+UDAP+2+0+Protocol+Specifications.htm}{LG UDAP 2.0 Protocol Specifications}.

    \chapter Plugin properties
    Following JSON file contains the definition and the description of all available \l{DeviceClass}{DeviceClasses}
    and \l{Vendor}{Vendors} of this \l{DevicePlugin}.

    Each \l{DeviceClass} has a list of \l{ParamType}{paramTypes}, \l{ActionType}{actionTypes}, \l{StateType}{stateTypes}
    and \l{EventType}{eventTypes}. The \l{DeviceClass::CreateMethod}{createMethods} parameter describes how the \l{Device}
    will be created in the system. A device can have more than one \l{DeviceClass::CreateMethod}{CreateMethod}.
    The \l{DeviceClass::SetupMethod}{setupMethod} describes the setup method of the \l{Device}.
    The detailed implementation of each \l{DeviceClass} can be found in the source code.
