Hi CSchulz,
I am using 1.5.x version and getting the below header in the final build file:

   /*!
es6-promise - a tiny implementation of Promises/A+.
Copyright (c) 2014 Yehuda Katz, Tom Dale, Stefan Penner and contributors (Conversion to ES6 API by Jake Archibald)

See https://raw.githubusercontent.com/stefanpenner/es6-promise/master/LICENSE

*/

I have used preamble config with empty string then too it is present.

@LalitKushwah the given extract is the normal header description of the es6-promise lib. That is not the preamble. You can't turn them off via configuration, they will be copied together.

Seems like this function is not actually used anywhere.

@CSchulz is there any way to turn them off ?

@LalitKushwah those kinds of comments are supposed to be preserved on purpose (for copyright/license info). Also, they only make up a couple bytes, so not sure why you care much about turning them off. Anyway, that's not related to this issue.

@simonhaenisch I understand this just asking for the query purpose.
