Update April-23-2016: Deprecated this package in favor of APEX Nitro [https://github.com/OraOpenSource/apex-nitro/]. Update Feb-28-2015: Added image optimization to the Gulpfile. Note: I have given a more interactive presentation in January 2015 at @InsumSolutions [https://twitter.com/InsumSolutions] office about how to integrate Gulp in your APEX workfow.
