You misunderstand the question.  Here's a concrete example:

Camaelon, EtoileBehavior and EtoileMenu all provide appkit user  
bundles.  They are each installed as separate packages.  A person  
creating a package for them wants to make them default for every  
user.  This requires:

1) When the package is installed, each needs to be added to the  
NSGlobalDomain GSUserAppKitBundles array.

2) When the package is uninstalled, each needs to be removed from the  
array.

Step 1 can, I believe, be accomplished with plmerge.  How would you go  
about doing step 2?
