This help controller has an API incompatible with wxWindows -wxHelpController!} - This help controller provides an easy way of displaying HTML help in your application (see {\it test} sample). The help system is based on {\bf books} (see \helpref{AddBook}{wxhtmlhelpcontrolleraddbook}). A book is a logical section of documentation (for example "User's Guide" or "Programmer's Guide" or -"C++ Reference" or "wxWindows Reference").
