why does this main function does nothing?

I see this strange python function

@click.group()
def main():
    pass

It is the main entrance function, but why does it do nothing?

If a function is decorated with @click.group, a Group is created, and can later be used to add subcommands, e.g.:

@click.group()
def main():
    pass

@main.command()
def sub():
    print('I am a subcommand')

The group function doesn't have to do anything itself, if you don't need additional logic or default logic without a subcommand.
