The proper way is: - find out who are the authors are (e.g. with `vc-region-history`). - check whether they have signed the copyright paperwork. - if they have not and the code is non-trivial, ask them to sign the paperwork. [ in this case, I suspect they all already signed. ] - ask them if they're OK to contribute that code to your GNU ELPA package and hence consider that code as covered yb their copyright assignment. - add their names to the `Author:` if you think the code is significant enough for that. The copyright line shouldn't need any changing since their paperwork assigns the copyright to the FSF anyway. Stefan
