It doesn't handle orders; use the `orders' property that is implemented
by release 5/12 of the library.
I have a more recent version of frobozzica.inf based on some code in
release 3 of "Christminster" that is somewhat more sophisticated but it
still needs some work.
You are aware, I take it, that there's already a directory in the IF
archive which contains many code samples:
/if-archive/programming/inform/examples/
