Yeah, I eventually found that, but only after I finally stumbled upon someone referencing the feature in a GitHub issue.

The --help is fine documentation for the people who have already installed the tool, but it doesn't help people like OP who just want a simple way to run multiple containers as a systemd unit and don't yet know that podman-compose has a solution.

That's why I said "poorly documented" instead of "undocumented". It's there once you know where to look.
