As an AI language model, I don't have access to a command line interface to use argparse. But here is an example of how argparse can be used in Python:
```
import argparse
parser = argparse.ArgumentParser(description='Process some integers.')
parser.add_argument('integers', metavar='N', type=int, nargs='+',
help='an integer for the accumulator')
parser.add_argument('--sum', dest='accumulate', action='store_const',
const=sum, default=max,
help='sum the integers (default: find the max)')
args = parser.parse_args()
print(args.accumulate(args.integers))
```
This script defines a command-line argument parser using the `argparse` module. The parser defines an argument `integers` that takes one or more integers, and an optional argument `sum` that will either sum the integers or find the maximum value. The script then parses the command-line arguments using `parse_args` and prints the result of either summing or finding the maximum value of the integers.
