[webkit-help] How to use WebPageSerializer

[n179911]

Hi,

In webkit source code, there is a WebPageSerializer.h file under
./WebKit/chromium/public/WebPageSerializer.h.
But in one of the files under WebCore, I tried to use it by adding
"#include "WebPageSeralizer.h", I get
 error: WebPageSerializer.h: No such file or directory

Can you please me how/if I need to modify the INCLUDE_DIR in Makefile
in order to WebPageSerializer?

Thank you.
