9 It doesn't work like this in our case. The Portage tree is licensed
10 under the GPL-2. If someone takes a subset of ebuilds from it, it will
11 be a "derivative work" and it cannot be distributed under any license
12 other than the GPL-2.
13
14 It is even doubtful if any third-party ebuilds added to such a tree
15 could be under a different license. If such ebuilds inherit from a GPL
16 licensed eclass or depend on (or are depended on by) other ebuilds,
17 they cannot "be reasonably considered independent and separate works
18 in themselves".
