> Ugh, you could probably split this starting from the end since we assume it will always end with at least three commas, but that's not a satisfying solution. I've been pondering creating a new tool to do this, but haven't quite decided how that should look. I'd imagine it would basically behave like how we invoke `fatbinary`.

I agree the issue is orthogonal to this patch.
Parsing backward is an option. Another option is to put file name at the end of the option. Maybe the latter is less confusing.
