Hello,

If I build an app that combines tslib with other code -- e.g. use TypeScript in an app -- as far as I understand the license header on https://github.com/Microsoft/tslib/blob/master/tslib.js, it requires me to include that copyright+license in the resulting product.

Is that intentional? I think when I use the TypeScript compiler without the --importHelpers flag, I do not have this additional requirement.
