BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.
