However, I hope the message can be as the following:

The `metavar` argument to `add_argument` can be used to control how an
argument is represented in the usage text:
```

If we have the following code:
```
parser = argparse.ArgumentParser(description="test")
parser.add_argument('path')

Run it without args, will get error message:

Haha. Yes a nice exercise, but has nothing to do with the original
question which is how to convince argparse to accept a string like that
without thinking it's a switch. Many unix utilities treat "--" as a
special argument that turns off argument parsing for the rest of the

nice if there were a neater option:

detection of the presence of the positional arg to the application.
Shouldn't I be able to tell argparse I'm going to process --verbose, then
exit?
Thx,

Depends on your definition of "broken". If you want to make a custom
integer type, yo

Hi,
With argparse's add_mutually_exclusive_group() I can add mutually
exclusive args, but how do I deal with a 3rd arg which only makes sense
for one of the mutually exclusive args?
