sywac CLI Parser

sywac (So You Want A CLI) is a Node.js library for parsing command-line arguments and building robust CLIs. It provides a fluid, asynchronous API for defining positional arguments, options, and complex nested commands, with features like type-based argument parsing and flexible auto-generated help content. The current stable version is 1.3.0. While its release cadence has been moderate, it remains an active project, most notably adding a `.strict()` mode in v1.3.0 for enhanced security against unknown flags. This differentiator helps prevent unexpected behavior from typos in sensitive operations. sywac is designed for Node.js environments (v4+) and focuses on a coherent API for both simple and complex CLI applications.
