Will the license notice scanner properly pick up the notice if it's in a file
named COPYING?

If not, please copy it to whatever the license scanner expects :)

README.chromium specified correct location for the license file:
http://codereview.chromium.org/10905108/diff/23001/third_party/opus/README.ch...
, so the license scanner should be able to find it.
