podman-apple-silicon.rb

# podman patched to work with Apple Silicon. Install it like this:
#
#     brew install simnalamburt/x/podman-apple-silicon
#
# You can run the linux VM for the podman container like this:
#
#     podman machine init       # Create a VM
#     podman machine start      # Start a VM
#     podman run -p 8080:80 docker.io/nginx   # Run a container
#
# It's based on my fork of development version of podman, and
# Alex Graf's Hypervisor.framework patch applied to the QEMU v6.1.0.
# See following links for the source codes of forks
