This one I'm going to need some help on, having never done this before
(obviously).

When and How to change the trunk update configuration:
* When you are adding a new package to trunk, update the configuration with
the new package (just because a package is in the repository does not mean
it is loaded)
* When you are removing a package from trunk, update the configuration to
remove the package (and follow instructions for removing the package)
* When methods are moved from one package to another - primarily when they
are used in the update logic - then create an update with the package where
the method is removed and where the method is added in the same update
configuration
* When you need to ensure a preamble or postscript script is run for a
package, include the version in a new configuration (otherwise it could be
skipped - trunk only loads the latest version of a package if specific
versions are not called out in the update configuration)
* If you need to do very intricate, step by step surgery on the internals
of Squeak itself, such as converting how contexts work, you should use a
series of update configurations to ensure step by step applications of the
packages so the trunk update is successful

To perform the modify the update configuration:
1. Update squeak.
2. Open the trunk package
3. Select the 'update' package, find the last update commit, and "Browse"
it (with the button)
4. In the MCConfigurationBrowser, press the "Update" button and choose
"update all from image"
5. If you need to add a new package, press the "Add" button and chose the
package to add (it needs to be in your image with the right version to add
it)
6. If you need to remove a package, select the package and press "Remove"
7. If you packages are updating that have dependencies between each other
(say, adding an abstract class to one package, and a subclass of that
abstract class in another package), then you will need to make sure those
packages are in the right order.  In this case, find the package with the
subclass, and make sure it is after the abstract classes package.  Do this
by selecting one package and pressing the "Up" and "Down" keys until the
packages are in the right order
8. Finally, save the package back to Trunk, and test out the update stream
to ensure it works.
