Newt repo license review

[Justin Mclean <ju...@classsoftware.com>]

Hi,

I took a look at the newt repo and it has a few issue that would need to be sorted for a release:
- Most of the licenses are Apache comparable
- logutils is MPL. This is a weak copyleft license and can only be used in binary not source form [A]
- YAML is LGPL which is not compatible with the Apache license [B] so I don’t think we can’t use that

While well intentioned I though this may be an issue:
./Godeps/_workspace/src/github.com/mattn/go-sqlite3/sqlite3-binding.c

But it should be OK as SQLite is public domain:
https://www.sqlite.org/copyright.html

Here’s a summary of all the licenses involved (we’ll need this when assembling LICENSE and NOTICE)
Burnt Sushi - permissive - perhaps too much so :-) See [1]
go curl Apache [2]
mousetrap Apache [3]
logutils MPL [4]
pretty MIT [5]
properties BSD (2 clause) [6]
go SQLite MIT  [7]
Mao structure MIT [8]
Cast MIT [9] + BSD [15]
Cobra MIT [10] + Apache [16]
jWalterWeatherman MIT [11] + BSD (go authors) [17]
pFlag BSD (3 clause) [12]
Viper MIT [13]
YAML LGPL [14]

Thanks,
Justin
