[pacman-dev] [PATCH v3 3/3] libmakepkg: check if PACKAGER has the expected format for WKD lookup

[Jonas Witschel]

pacman should be able to extract an email address from PACKAGER for WKD
lookup, so issue a warning if it is not of the form
"Example Name <email at address.invalid>". Neither the name nor the email
address must contain additional angle brackets.
