1. wxDir works for MSW and documented

2. wxDateTime works with dates very close to the Epoch
3. setting font for wxRadioBox works

+\section{\class{wxDir}}\label{wxdir}
+
+wxDir is a portable equivalent of Unix {open/read/close}dir functions which
+allow enumerating of the files in a directory. wxDir allows enumerate files as
+well as directories.
+
+Example of use:
+
+\begin{verbatim}
+    wxDir dir(wxGetCwd());
+
+    if ( !dir.IsOpened() )
+    {
+        // deal with the error here - wxDir would already log an error message
+        // explaining the exact reason of the failure
+        return;
+    }
+
+    puts("Enumerating object files in current directory:");
+
+    wxString filename;
+
+    bool cont = dir.GetFirst(&filename, filespec, flags);
+    while ( cont )
+    {
+        printf("%s\n", filename.c_str());
+
+        cont = dir.GetNext(&filename);
+    }
+\end{verbatim}
+
+\wxheading{Derived from}
+
+No base class
+
+\wxheading{Constants}
+
+These flags define what kind of filenames is included in the list of files
+enumerated by GetFirst/GetNext
+
+{\small
+\begin{verbatim}
+enum
+{
+    wxDIR_FILES     = 0x0001,       // include files
+    wxDIR_DIRS      = 0x0002,       // include directories
+    wxDIR_HIDDEN    = 0x0004,       // include hidden files
+    wxDIR_DOTDOT    = 0x0008,       // include '.' and '..'
+
+    // by default, enumerate everything except '.' and '..'

+error occured.
+
+\membersection{wxDir::IsOpened}\label{wxdirisopened}
+
+\constfunc{bool}{IsOpened}{\void}
+
+Returns TRUE if the directory was successfully opened by a previous call to 
+\helpref{Open}{wxdiropen}.

+empty) and flags, return TRUE on success.
