appropriate class is aliased to the name wxHelpController for each platform, as follows:
\begin{itemize}\itemsep=0pt
-\item On Windows, wxWinHelpController is used.
+\item On desktop Windows, wxCHMHelpController is used (MS HTML Help).

explicitly by an application that wishes to make use of them.
There are currently the following help controller classes defined:
\item wxWinHelpController, for controlling Windows Help.
\item wxCHMHelpController, for controlling MS HTML Help. To use this, you need to set wxUSE\_MS\_HTML\_HELP
to 1 in setup.h and have htmlhelp.h header from Microsoft's HTML Help kit (you don't need
-VC++ specific htmlhelp.lib because wxWindows loads neccessary DLL at runtime and so it
+VC++ specific htmlhelp.lib because wxWidgets loads necessary DLL at runtime and so it
works with all compilers).
\item wxBestHelpController, for controlling MS HTML Help or, if Microsoft's runtime is
not available, \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller}. You need to provide
{\bf both} CHM and HTB versions of the help file. For 32bit Windows only.
\item wxExtHelpController, for controlling external browsers under Unix.
The default browser is Netscape Navigator. The 'help' sample shows its use.
+\item wxWinceHelpController, for controlling a simple {\tt .htm} help controller for Windows CE applications.
\item \helpref{wxHtmlHelpController}{wxhtmlhelpcontroller}, a sophisticated help controller using \helpref{wxHTML}{wxhtml}, in
a similar style to the Microsoft HTML Help viewer and using some of the same files.
Although it has an API compatible with other help controllers, it has more advanced features, so it is
