SEO META Crawler

I was a little bored...

So I thought I'd write some php script to crawl a given URL using PHP and CURL funcs and fetch the SEO sensitive data ;-) then extract ==>
<TITLE> and all the <META> tags

I figured this crawler..  followed by some form of analysis might be useful for SEO purposes.
( I do have other utilities to crawl a given URL and extract Keywords by Density ).

I've already tested this by crawling the landing pages of some of my own sites and some of my friends' sites ...
Interesting data.... ;-)
