Hi Richard,

Correct me if I'm wrong, you are asking if this script will create new packages which will upgrade cleanly? The build scripts use an incrementing version counter which dpkg should pick up on, so if you perform a nightly/weekly build then you'll be able to upgrade the package (whether it will apply cleanly or not is another question, of course!).

Let me know if I misunderstood your question - otherwise hope this helps!
