Request #37768 has been Rejected by AkechiShiro [1]: Closing this request as upstream does exist, an error is in the URL (an underscore _ where there should be a dash -) : https://github.com/fonttools/openstep-plist
Led me to believe the repo was deleted, when it wasn't. [1] https://aur.archlinux.org/account/AkechiShiro/
