def main():
    """
    The **carbontracker** CLI allows the user to track the energy consumption and carbon intensity of any program.
    [Make sure that you have relevant permissions before running this.](/#permissions)

    Args:
        --log_dir (path, optional): Log directory. Defaults to `./logs`.
        --api_keys (str, optional): API keys in a dictionary-like format, e.g. `\'{"electricitymaps": "YOUR_KEY"}\'`
        --parse (path, optional): Directory containing the log files to parse.

    Example:
        Tracking the carbon intensity of `script.py`.

            $ carbontracker python script.py

        With example options

            $ carbontracker --log_dir='./logs' --api_keys='{"electricitymaps": "API_KEY_EXAMPLE"}' python script.py
