/** This header generates the following template classes with a variable number
    of interfaces:
    
    comphelper::ImplHelper<N> <typename Ifc1, ..., typename Ifc<N> >
    comphelper::WeakImplHelper<N> <typename Ifc1, ..., typename Ifc<N> >
    comphelper::WeakComponentImplHelper<N> <typename Ifc1, ...,

                                          typename Ifc1, ..., typename Ifc<N> >

    as already present in headers cppuhelper/implbase<1-12>.hxx and
    cppuhelper/compbase<1-12>.hxx.
    <N> denotes the number of interface types passed as template arguments.
    Don't use this header for interface numbers up to 12;
    always use the existing cppuhelper/(impl|comp)base<1-12>.hxx headers
    for this purpose, which eases debugging.
    
    Including this header requires a little discipline, because it has no
    include guards.  Please use the following external include guard rule
    where <N> is the number of interface types:
    
    #if ! defined(INCLUDED_COMPHELPER_IMPLBASE_VAR_HXX_<N>)
    #define INCLUDED_COMPHELPER_IMPLBASE_VAR_HXX_<N>
    #define COMPHELPER_IMPLBASE_INTERFACE_NUMBER <N>
    #include "comphelper/implbase_var.hxx"
    #endif

    Additionally you can

    #define COMPHELPER_IMPLBASE_MAX_CTOR_ARGS <N>

    to control the maximum number of templated ctor arguments for the
    ImplInheritanceHelper<N> classes.
    The default is a maximum of 6 arguments.
