[talk-au] JOSM multipolygon how-to?

[Sam Wilson]

This might not be of use, but if you're trying to add a multipolygon for 
a building with a hole in it then in JOSM it's really easy:

 1. Use the building tool to create multiple rectangles over the
    building, including any courtyard.
 2. Select all the building rectangles, with the courtyard one last (or
    at least, not first).
 3. Press shift-J to join them all together. It magically makes the
    required relation.
