Which is what The Apache 1.1 license is (i.e. a modified BSD one) it’s been a
while since I’ve looked at the text from ALv1.1. As far as a release goes IMO
the LICENSE txt needs to go in (or be pointed at) in LICENSE,  nothing
should be added to NOTICE  (as the text is included in LICENSE) and the
headers should be left on the existing code as is.
