sort out licenses
We should come to an agreement about licenses in this repo.
For source code I see the following candidates:
- viral ones: GPL 2/3, AGPL
- closed source friendly ones: LGPL variants, BSD likes (including MIT)
- others?
Any preferences/objections here? If not, I would simply go with MIT.
I have absolutely no clue about proper licenses for written text and additional stuff. Is it a good idea to just put it under the same license as the source code? Do we need a separate license for this, something from Creative Commons? As additional stuff I mostly see some formal writups of parser definitions, along with grammar files.
