    comimpl.xsl:
        XSLT stylesheet that generates COM C++ classes implementing
        interfaces described in VirtualBox.xidl.
        For now we generate implementation for events, as they are
        rather trivial container classes for their read-only attributes.
        Further extension to other interfaces is possible and anticipated.
