This page needs an example output to see what one can expect from the tool and there should be a better way then a git checkout to install. A rubygem that adds a binary perhaps.
Edit: misstook it for a command line tool. This is great!
I get spurious error messages about the clock being incorrect on some sites - it will say it's in the future, but the time reported looks correct to me.
Thanks! This is great, it found a few problems with my stuff.
Nice project. Should also check the Vary header.
One of the problems it found with a site of mine was that it doesn't send Vary consistently.
