Wow, looks like ubuntu includes chromium in their universe repo ["community
maintained open source software"]. Yet if we look at the copyright file [1]
for the latest release, there is plenty of files with License: UNKNOWN and
files supposedly under some variant of BSD with Copyright: UNKNOWN. (All BSD
licenses require the name of the copyright holder to be preserved.)
Looks pretty messy to me.
