I'm trying out Rune for a player in my car, and so far it seems to be suitable. I need to install Triggerhappy to interface with my steering wheel controls. I'm used to Debian based systems - no experience at all with Arch. Pacman has no listing of it, I have downloaded PKGBUILD from repository https://aur.archlinux.org/packages/triggerhappy-git/ but I have no idea how to proceed.
