Hello Ralf,

I haven't had a chance to play with the new changes, but at a quick
glance it seems to be a good solution and one I am happy with (it would
only require a few minor changes to my existing script). If I happen to
notice anything else down the track, I can always create a new issue. So
I would consider this issue "done" and thanks for helping to get the
changes committed.

Cheers,
John.
