header-comment

To host on jsDeliver, a header-comment is totally optional, but I recommend it because: https://github.com/tomByrer/web-engeneering-notes/blob/master/banner-tips.md#mini-banner

An extra blank space at end is a common EOF marker, also optional but helpful.

These are only suggestions; feel free do as you wish. Sorry I don't know RAKE or else I would have automated this for you :)
