Update to D6

I still haven't studied thoroughly the D6 theme system. I will do so soon and will try to understand what is the best solution for it.
I understand there might be a built-in feature in D6 for that kind of task.

If you have any suggestions, please share them here.

Just an update: I'll have a look into porting this module to D6, but it seems to me that the same functionality can now be achieved, using the improved sub-themes system.
So either I'll update the module to D6, or provide an explanation on how to achieve the same effect. without using this module.

I ported this for a client of mine.

@cwells: That's cool. I'll check it out.
