Thanks to all for your helpful replies.
It seems reasonable to consider that the whole package is indeed
licensed under GPL >= 3, and I can therefore remove the LICENSE file.
The Qhull COPYING.txt notice is included in the inst/doc directory, as
required by the Qhull licence, so I think all should be OK.
If the CRAN maintainers are happy with this proposal, that will resolve
a major R-packaging headache, so thanks again.
