Python doesn't include the interpreter in `sys.argv`:
```
aidengrossman-mac2:build aidengrossman$ python3 /tmp/test.py hello
['/tmp/test.py', 'hello']
aidengrossman-mac2:build aidengrossman$ cat /tmp/test.py
import sys

print(sys.argv)
aidengrossman-mac2:build aidengrossman$
```

Point taken about `argparse` though. I'll wire that up.
