Packaging for Arch with the openSUSE Build Service
Register an account at https://build.opensuse.org then upload the PKGBUILD, source tarball any any files in the source array.
There are some limitations (no gpg checking because each package is built in a fresh VM) and big packages will fail because of lack of RAM but on the whole it works really well and even allows split packages.
Easier than an AUR helper :)
