    \title QtDBus XML compiler (qdbusxml2cpp)
    \keyword qdbusxml2cpp

    The QtDBus XML compiler is a tool that can be used to parse interface descriptions and produce
    static code representing those interfaces, which can then be used to make calls to remote
    objects or implement said interfaces.

    \c qdbusxml2dcpp has two modes of operation, that correspond to the two possible outputs it can
    produce: the interface (proxy) class or the adaptor class. The latter consists of both a C++
    header and a source file, which are meant to be edited and adapted to your needs.

    The \c qdbusxml2dcpp tool is not meant to be run every time you compile your
    application. Instead, it's meant to be used when developing the code or when the interface
    changes.

    The adaptor classes generated by \c qdbusxml2cpp are just a skeleton that must be completed. It
    generates, by default, calls to slots with the same name on the object the adaptor is attached
    to. However, you may modify those slots or the property accessor functions to suit your needs.
