 `auto_cli` is a tool for calling Python functions directly from the command-line, without the need for writing argument parsers. Instead, the argument parser is automatically generated from the annotation of the function, including default arguments and types. When you use `auto_cli`, you can still use your Python functions from code without any changes. In fact, you can use `auto_cli` to generate a CLI for functions in a stand-alone script, or for an external library, as long as the functions have type annotations.
