+\func{static void}{AddHandler}{\param{wxFileSystemHandler }{*handler}}

+This static function adds new handler into the list of handlers.
+The \helpref{handlers}{wxfilesystemhandler} provide access to virtual FS.

+\wxheading{Note}
+
+You can call:
+
+\begin{verbatim}
+wxFileSystem::AddHandler(new My_FS_Handler);
+\end{verbatim}
+
+This is because (a) AddHandler is a static method, and (b) the handlers
+are deleted in wxFileSystem's destructor so that you don't have to
+care about it.
