Add a leading comment to a compiled typescript file

Im kind of new to typescript. I'm searching for a method to tell typescript to add a leading comment at the top of a compiled file.

So e.g., I want

foo.ts

export class Bar {}

to get compiled to

foo.js

/*-----This is a compiled typescript file, see ... for more-----*/
export class Bar {}

Is there an option for that, or how could i solve this ?
