Question about trunk sample includes, should <> be used instead of ""

[Tim S]

I have an question about trunk sample code includes, should <> be used 
instead of "" in the #include section like in case of below?

// For compilers that support precompilation, includes "wx/wx.h".
#include "wx/wxprec.h"

#ifdef __BORLANDC__
     #pragma hdrstop
#endif

// For all others, include the necessary headers (this file is usually 
all you
// need because it includes almost all "standard" wxWidgets headers
#ifndef WX_PRECOMP
     #include "wx/wx.h"
#endif

What I think it should be
#include <wx/wxprec.h>
#include <wx/wx.h>

I have an idea that replaces the include of wx/wx.h with a new header of 
   wx_forward.h an header that does forward declarations of wxWidgets 
classes. And, I think it might be a good idea to change the quotes to 
square brackets at the same time.
