Actual package recipes. BSD-style packaging systems are written in BSD make using a mk/ framework rather than Arch-style shell scripts. If a package already exists for FreeBSD Ports I would check that first because it's much more similar to what I'm used to.
Fundamentally pkgsrc is built on very low level tools, awk, shell, make, cwrappers, and pkg_install, although you can manage it with high-level ones (obviously pkgin is there, but there's also a lot of other third-party tooling).
