This command generates GPL license headers on top of all source files.
You can run it once per month, before cutting a release or just
whenever you feel like it.
go run update-license.go
The copyright in each file is assigned to any authors for which git
can find commits in the file's history. It will try to follow renames
throughout history. The author names are mapped and deduplicated using
the .mailmap file. You can use .mailmap to set the canonical name and
address for each author. See git-shortlog(1) for an explanation
of the .mailmap format.
Please review the resulting diff to check whether the correct
copyright assignments are performed.
