Symphony.

I recently released a Gulp based fronted build system called Longsip and this morning I've made a customised fork pre-configured for use with Symphony 2.5+ Symphony-Longsip It might be of interest to anyone wanting a plug-n-play gulp/symphony setup, or as a base for developing their own.

Thers are reasonably comprehensive docs so I won't repeat those here, but the headline features include support for Browserify, Polymer Web Components, BrowserSync (inc. proxying local development server), Stylus & Autoprefix CSS.

Edit: (5th-Oct-2014): Project name has changed to 'Longsip' - github URLs above have been changed to reflect.

Interesting, thanks! Looking forward to trying this out.
