Door: close the door

[matt-jordan]

When you have an open door, you need to be able to close it:

[north] door

$ close door

You close the door.

The rest of the room should see this:

> so and so closes the door.

In the destination room, we wouldn't be able to see who did it, but we would see that it happens:

> door closes.

Of course, if things don't work, we should be told so:

[north] (door)

$ close door

The door is already closed.
