+\subsection{Using embedded resources}\label{embeddedresource}
+
+It is sometimes useful to embed resources in the executable itself instead
+of loading external file (e.g. when your app is small and consists only of one
+exe file). XRC provides means to convert resources into regular C++ file that
+can be compiled and included in the executable. 
+
+Use the {\tt -c} switch to
+{\tt wxrc} utility to produce C++ file with embedded resources. This file will
+contain a function called {\it InitXmlResource} (unless you override this with
+a command line switch). Use it to load the resource:
+\begin{verbatim}
+  extern void InitXMLResource(); // defined in generated file
+  ...
+  wxXmlResource::Get()->InitAllHandlers();
+  InitXmlResource();
+  ...
+\end{verbatim}
