However, I would like you clarify the '::Argument locations:' marker.
Do you intend the double colons '::' as token to introduce
some form of meta data for tools? (In this case, it is to introduce
locus, but is it an escape for more general tags?)Yes, exactly. I don't insist on using ::. It was the first thing that occurred to me. If someone has a better idea, let's use it.
