All ebuilds: LICENSE="GPL-2" I tried to run scancode-toolkit on: 2019.03.17.09.24.57, but gnulib has "license" written everywhere, so that doesn't give useful output. I couldn't find anything that licensed -only with grep. Under lib/ I found files licensed under: GPLv2+, GPLv3+ and LGPLv2.1+ Under doc/ I found files licensed the GFDLv1.3+ Therefore, it should be: LICENSE="GPL-3+ LGPLv2.1+ FDL-1.3+"
