impulse [1] filed a deletion request for libappanvil-git [2]: Please delete this package of mine, as explained in the pinned comment, its superseded by the 'appanvil-git' pkg which provides the lib and program in one. also libappanvil has almost no usecase currently outside being used with the appanvil program. Upon reflection it was probably unnecessary for me to separate them in the first place.
Many Thanks, James Clarke [1] https://aur.archlinux.org/account/impulse/ [2] https://aur.archlinux.org/pkgbase/libappanvil-git/
