- * GitHub Action can provide multiple executable entrypoints (pre, main, post),
- * but it is complicated process to generate multiple `.js` files with `ncc`.
- * So we rather generate just one entrypoint, that is symlinked to multiple locations (main.js and post.js).
- * Then when GitHub Action Runner executes it as `node path/to/main.js` and `node path/to/post.js`,
- * it can read arguments it was executed with and decide which file to execute.
- * The argv[0] is going to be a full path to `node` executable and
- * the argv[1] is going to be the full path to the script.
- * In case index.js would be marked executable and executed directly without the argv[1] it defaults to "main.js".
