/* htmlsys.h : wxHtmlHelpSystem is an extension of the wxHtmlHelpController.
* mainly does two things:
* - extend the interface somewhat so the programmer can dictate most of the
* look and feel of the htmlhelp frame.
* - make some protected functions public (adding _ to the function name) so
* that SWIG can wrap them.
