Access Command Line arguments

How Can I access Command line arguments in mojo like we do in python using sys:

import sys
print(sys.argv[1])

import sys
print(sys.argv[1])

import sys
print(sys.argv[1])

import sys
print(sys.argv[1])

Trying the same in mojo:

import sys

fn main() raises:
    print(sys.argv[1])

import sys

fn main() raises:
    print(sys.argv[1])

import sys

fn main() raises:
    print(sys.argv[1])

import sys

fn main() raises:
    print(sys.argv[1])

Yeilds the following error:
error: 'argv' expects 0 input parameters, but 1 was specified
print(sys.argv[1])
