/* 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.
