[OpenSCAD] (newbie 1st post) Cutout with rounded edges

To make the outside I would take the hull of four rounded cylinders placed
at the corners. You can find those in my library:
To make the slot I would subtract the hull of two cylinders, or use my slot
If I wanted the slot at the origin I would simply model it at 0,0 and place
the corners where they should be relative to that.
