--harmony-generators flag

[ghost]

I'm using duo in a gulp build script. I've been a little behind on updating, and have begon updating to the latest duo version (pr here, and duo build script). However, from what I understand duo now needs to be run with the node --harmony-generators flag.

Which is a problem for me, since I'm using gulp and not node directly. Now I can get everything to work as expected by running:

node --harmony-generators node_modules/gulp/bin/gulp.js build

But of course, I'd just like to be able to use gulp build. Is there a way solve this from within duo, without modifying my entire build process? I'm asking here because this is sort of a duo-specific requirement, and I'd like to solve this as close to duo as possible.

I've solved this for myself with https://github.com/dcodeIO/node-harmonize, but thought this would still be a valid duo issue. Since I couldn't really find any info in the documentation on duo requiring the --harmony-generators flag, or only working with iojs (which has generators turned on by default).

In my opinion It would be helpful to add this requirement to the docs (if the --harmony-generators flag can't be enabled from within duo).
