The tasks are defined in www.squeaksource.com/Packages in the
Packages-Library packages.

Within that package there is a class PackagesDevU whose instance side
methods provide package definition metadata that has been
obtained/gernerated from Universes. The class PackagesDev inherits and
overrides the PackagesDevU with any further information.
