dagr is a lean and mean ruby client for the IPFS api.
Regarding licence terms:
I'm releasing this under three licences (GPLv3, AGPL3, and MIT) in this particular case because my working theory is that making a p2p **library** easier to use for more people hurts centralists more, and I'm leaving it up to you to decide which will help you better to achieve that goal with your particular **application**.
