# The CMD expects that the podman git repository is bind mounted to /podman.
# The generated documentation will be copied to ./docs/build/remote/.

# Example usage:
#   podman build --build-arg TARGET_OS=windows -t podman-docs-generator $(pwd)/docs
#   podman run --rm -v $(pwd):/podman podman-docs-generator
