Hi emacsers

I'm wondering is there any existing lisp code snippet to get title of web
page by url.
Such as, given "http://www.emacswiki.org/emacs/Git", we will get the title
of this web page, which is "EmacsWiki: Git:".

Function of w3m-current-title is quite close, but a standalone lisp function
is much preferred.
