The script will automatically detect if a matching `configs/{song-name}.json` file exists and pass it to the `chordpro` executable to be mixed with/override the global `./config.json` file.
Once complete, the output file(s) can be found at `./out/{song-title}.{format}`.
+The script will also parse any `{x_???:val}` directive and add it as a `--meta` argument to the chordpro command.
+Each chordpro file should at a minimum include a `{x_revision:1}` directive.
+This value is printed in the footer; see `./config.json` for the global footer definition.
+
For a list of all available output formats, see the official `chordpro` command [output documentation](https://www.chordpro.org/chordpro/using-chordpro/#output).
