[webkit-help] New directory structure in Webkit

[n179911]

Hi,

After I upgate my Webkit source using 'git pull', but after that , I
see these directories as 'untracked files':
JavaScriptCore, JavaScirptGlue, WebCore.

Can you please tell me why is that? Does Webkit change the code
structure? But whey 'git pull' does not update it?

Thank you.
