synopsis:Benchmark user-perceived page time for a list of URLs using a true WebKit browser

Mac OS X-specific tool which uses PyObjC to load pages in WebKit. Takes URLs on the command-line or in a separate file and runs through them as quickly as possible, measuring the time it takes from beginning the request until the browser fires the didFinishLoadForFrame event, which includes things like image loading, Flash, JavaScript, etc. for measuring user-perceptible page-load performance.
