I'd class this as a bug, since the documentation suggests it should
work. Fortunately, it's rather easy to fix, so I'll post a patch for
it soon.
If you're feeling adventurous and can't wait for a new release with
the fix, you can use the attached file to overwrite your installed
scm/framework-ps.scm file.
Regards,
Neil
