<borja@codigo23.net>, ok abieber@ - apologies for the extra copies of
WebKit and Qt but they are stripped-down so not horribly slow to build,
and have various fixes that phantomjs upstream haven't been able to get
into the various libraries yet.
"PhantomJS is a headless WebKit scriptable with a JavaScript API.
It has fast and native support for various web standards: DOM
handling, CSS selector, JSON, Canvas, and SVG."
(useful for various things including automated testing of web sites,
and screen scraping of complex web apps)
