+/**
+ * This script downloads mxd executable from github actions
+ * Original repo: github.com/koitococo/mxlite
+ *
+ * To use this script, set the following environment variables:
+ * - COMMIT: The commit hash of the build you want to download.
+ * - PLATFORM: The platform of the build you want to download (windows, linux-gnu, linux-musl, darwin).
+ * - ARCH: The architecture of the build you want to download (x86_64, aarch64).
+ * - GITHUB_TOKEN: A GitHub token with permissions to access actions.
+ *
+ * If the artifact is found, it will be downloaded as 'artifact.zip'.
+ * If no artifact is found, it will log an error message and exit with code 1.
+ *
+ * To run this script, ensure you have the octokit package installed:
+ *
+ * ```bash
+ * npm install octokit
+ * ```
