License

I would suggest to add a license.

The script is possibly not yet copyrightable (or it's not clear to me if it is, because it's very concise and its functionality closely related to the use of the github API), however as a matter of custom/practice, it's better IMHO if licensed as the other relevant repos are.

(I didn't add GPLv2 to my proposal, because it seems overkill, simply it's bigger than the script :))
