metatags library

Hi,

I want to check what this is for.

Is it for generating your own meta tag info, or does it scan another url (another domain) and gives you the meta info for that?

If its the 2nd, then how does it work?

Thanks.

Anyone know?

Also, why isn't the $url variable set? And when setting it, causes the script to break.
