I think I might have found out how: run 
PreferencesClass>>installHaloSpecsFromArray: passing it an array in the same 
format as the one that Preferences class>>customHaloSpecs or 
PreferencesClass>>classicHaloSpecs retruns.

This way, you can include halos in a package.  (I think, I don't know about 
removing them later.)

Thanks for the pointers (or references, in Smalltalk).
