[Seaside] Minimal image for deployment?

[AA]

How does one go about building a minimal image for deployment?  The Seaside book (Chapter 23.1) advises removing unnecessary packages - but there are a HUGE number of packages in the default Seaside 3 image.  Surely it's more efficient to add than subtract?  I've been using this page: http://code.google.com/p/seaside/wiki/LoadOrder as a guide.

Also, what happened to the Seasider 'builder' that was on seaside.st a few months back?  Obviously there was a good reason it was taken offline, but it was a great idea!
