Group and abelian group objects in the category of Kelley spaces

Hi all, Does anyone know of a good place where someone has written down the basic properties of such objects? As an example, if we have an (abelian, say) topological group, there is a natural uniform topology on the group such that the operations are uniformly continuous. Does the same hold for abelian group objects in the category of Kelley spaces? But anything would be helpful. Bill Rowan
