+
+Enumerate all files and directories under the given directory recursively
+calling the element of the provided \helpref{wxDirTraverser}{wxdirtraverser} 
+object for each of them.
+
+More precisely, the function will really recurse into subdirectories if 
+{\it flags} contains {\tt wxDIR\_DIRS} flag. It will ignore the files (but
+still possibly recurse into subdirectories) if {\tt wxDIR\_FILES} flag is
+given.
+
+For each found directory, \helpref{sink.OnDir()}{wxdirtraverserondir} is called
+and \helpref{sink.OnFile()}{wxdirtraverseronfile} is called for every file.
+Depending on the return value, the enumeration may continue or stop.
+
+The function returns the total number of files found or {\tt (size\_t)-1} on
+error.
