Author: imp Date: Fri Dec 13 22:32:05 2019 New Revision: 355737 URL: https://svnweb.freebsd.org/changeset/base/355737 Log: Better copyright advice Document the common practices around copyrights with "all rights reserved" in them as new copyright notices get added. It's an open question qhether to point people at the fact that since the Berne convention was ratified, All rights reserved is largely obsolete. https://en.wikipedia.org/wiki/All_rights_reserved#Obsolescence has the details. The committer's guide will be revised shortly, and it's likely that's a better place for this discussion. If not, I'll add a blurb here.
