Hi Tim,

I wrote it and I don't remember sufficient detail.

The idea was part of a suite of capabilities for the Squeak4.1 "new development model".

The capability was that each version of squeak would be created by applying a crafted script to the previous version, rather than hacking away at a trunk repo.

The scripts for various targets could be tested out and edited by contributors as it was embedded in a wiki page. Bug fixes were supplied by mantis, and called up by fix numbers, and the code was found embedded in mantis pages.

These scripts would also unload as many palaces from the main image as possible, moving them into a curated list of packages (Sake/Packages).

Bob the Builder, a continuous integration and testing tool also built on Sake, would run the scripts, build and test the images, periodically or whenever anything changed.
