Use recent best practices for Copyright form at the top of the license: 1. Remove all the All Rights Reserved clauses on our stuff. Where we piggybacked others, use a separate line to make things clear. 2. Use "Netflix, Inc." everywhere. 3. Use a single line for the copyright for grep friendliness. 4. Use date ranges in all places for our stuff. Approved by: Netflix Legal (who gave me the form), adrian@ (pmc files)
