[arch-general] PKGBUILD contributor, maintainer, author...

Hello Arch, i'm doing (for fun) a PKGBUILD parser in javascript, and now as i was testing it with random PKGBUILD files from AUR, i noticed that there is more than one way people use to define authors... (/usr/share/PKGBUILD.proto shows only "Contributor") till now i've found: - Contributor - Maintainer - Author so i wonder what others should i parse ? or could you/we make a standard ? cheers .andre
