Is it required to include both scripts in html page? about es6-promise

[yairEO]

I also don't understand from the README what is the difference.
very poor explanation:

Automatically provides/replaces Promise if missing or broken.

That is the whole essence of a polyfill...of course this is what it does, question is what does "auto" means...since every polyfill is obviously "auto" and only applies if internally detected it should apply.

What I found out testing a jsPDF page with IE and looking at the code:

• es6-promise.auto.js seems to work like any polyfill so promises can be used automatically by scripts that require it, I guess with es6-promise.j you can only use the script implementation manually.
• including es6-promise.auto.js seems to be enough, including both shouldn't cause trouble.
• I would only use es6-promise.auto.js, if you need the polyfill that will do it. If you want to manually use the script implementation with either version of the script you can use ES6Promise
