Argvee is a command-line argument parser for Node.js that processes `process.argv` into an object with helpers for querying commands, modes, and parameters. It recognizes three types of arguments: commands (non-prefixed keys), modes (single or double-hyphen prefixed keys), and parameters (key-value pairs). This library is ideal for developers building Node.js CLI tools who need a simple and effective way to parse and handle command-line arguments.
