Node-far is a simple test runner for Node.js that finds and executes multiple JavaScript files, providing useful output and exit code information. It's designed to be a good Unix citizen, writing non-essential output to stderr and only the final result to stdout, making it easy to combine with other tools like `find` and `xargs`. The project is ideal for developers who need a lightweight, configurable test runner that can handle multiple test files and directories with flexible include/exclude filters.
