opts Command-Line Argument Parser

`opts` is a lightweight command-line argument parser for Node.js, currently at version 2.0.2. It provides functionalities for parsing short (`-s`) and long (`--long`) options, as well as positional arguments, and automatically generates help text. A key differentiator is its minimal footprint and zero external dependencies, designed to work as a standalone JavaScript file without requiring NPM or other package managers. This makes it suitable for projects prioritizing simplicity and a small bundle size. While primarily a plain JavaScript library, it ships with TypeScript definitions for enhanced development experience. `opts` processes arguments through callbacks associated with each option, rather than returning a structured object of parsed values. Its stable nature suggests a focus on maintenance, offering a robust solution for basic to moderate CLI parsing needs.
