argly (the raptor‑args package) is a lightweight, configurable command‑line argument parser for Node.js. It lets developers define options with short/long aliases, data types (strings, booleans, arrays, complex nested structures), automatic help/usage generation, validation and error handling—all with a concise, DRY‑style configuration. It’s aimed at JavaScript/Node developers who need a flexible, type‑safe alternative to libraries like optimist, yargs or minimist.
