MarsSeed [1] filed a deletion request for perl-pocketio [2]: I suggest to delete this deprecated, unfinished Perl library. Development stopped in 2014. It was a Perl reimplementation of Socket.io NodeJS server. But this does not support Socket.io clients with the newer v1 and v2 API's, only with Socket.io v0 API. That means it is not useful in any way. On MetaCPAN, there are only two consumers, one is abandoned in 2012 and the other was only an experimental library created and abandoned in 2015. On AUR there are no dependents. Therefore it's safe to delete this package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/perl-pocketio/
