-/**
- * Script to clone repositories, install dependencies, transpile code, and start an HTTP server.
- *
- * The script performs the following steps:
- * 1. Clones any missing repositories.
- * 2. Installs NPM dependencies in specified directories.
- * 3. Starts the transpiler (`grunt transpile --live`) and monitors its output.
- * 4. Once initial transpiling is complete, starts the HTTP server (`http-server -p 80 -c`).
- * 5. Handles process lifecycle to keep both the transpiler and HTTP server running.
- *
- * TODO: https://github.com/phetsims/chipper/issues/1345
- * "update-v1": "npm install && bash bin/sage run js/scripts/update-v1.ts && npm run start-v1",
- * "start-v1": "npm install && bash bin/sage run js/scripts/start-v1.ts",
