Copyright stuff

[jbenet]

At some point we lost the discussion on copyright and how the DCO works. how it works in a commit is there, but the large discussion we grabbed from Docker's contribute.md is gone. we should add it back so people can understand what it means legally.

I'm not sure I can remember the older discussion, might have been moved before I got here. I can search for it, though? Do you know what files it was in?

[jbenet]

Contribute.md i think-- if not look at Docker's, wherever they explain their use of DCO? not sure if i wrote it or took it from theirs.

[RichardLitt]

Do you mean #31? This is the only thing I can find that looks similar.

[jbenet]

i think we covered it already? i recall writing something about DCO recently in a PR with you

Closed in #83.
