    @class wxGenericAboutDialog

    This class defines a customizable @e About dialog.

    Note that if you don't need customization, you should use the global
    wxAboutBox() function that is both easier to use and shows the native
    dialog if available.

    To use this class, you need to derive your own class from it and override
    the virtual method DoAddCustomControls().

    To instantiate an object from your wxGenericAboutDialog-based class, you
    can use either the default constructor followed by a call to Create(), or
    directly using the alternate constructor. In either case, you have to
    prepare a wxAboutDialogInfo containing standard informations to display in
    an about-box.

    Example of usage, MyAboutDlg being a class derived from wxGenericAboutDialog:
    @code
    void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
    {
        wxAboutDialogInfo aboutInfo;

        aboutInfo.SetName("MyApp");
        aboutInfo.SetVersion(MY_APP_VERSION_STRING);
        aboutInfo.SetDescription(_("My wxWidgets-based application!"));
        aboutInfo.SetCopyright("(C) 1992-2012");
        aboutInfo.SetWebSite("http://myapp.org");
        aboutInfo.AddDeveloper("My Self");

        MyAboutDlg dlgAbout(aboutInfo, this);
        dlgAbout.ShowModal();
    }
    @endcode
