Squish is a way of writing fast, static HTML sites.
Instead of re-requesting every time you want another page from the site, Squish takes all your pages and caches them in Javascript on whatever page you're on.
• Squish can't replace <body> tags just yet. That means if you're putting classes on your <body> tag, you're outta luck. Put a <div> around your content with your classes and you're golden. Pull request or GTFO.
• Because pushState doesn't work under file:/// URLs, neither does Squish. You may want to use http://anvilformac.com/ ;)
