Re: purging entries for schemas no longer installed?

I think we can add a remove-local-gconf script to the "post" part when
we build the package. (if you are under rpm package manager). 

We can add a very powerful uninstall application to this script. So we
can follow the instruction of this uninstall application to whether
remove or backup our local data. It depends on the developers of each
application.
