Hey Cheng, a couple of comments on this:
- In Java, we should be able to run without a `--primary` if only `--jars`
and `--main-class` are given. I'd rather support that than add the primary
argument here.
- If we do this, then the `--primary` argument becomes relevant only for
Python, and we can give it a specific name there, e.g. `--main-file`. Another
option is to add `--module` and execute the `__main__` function in a specific
module with `python -m module-name`. This is the more Pythonic way to do it
AFAIK but it will also be more work, so I'd just stick to `--main-file` in 1.1
and add `--module` later.
