I agree with Matt, I think for the user-facing portion of this it doesn't make much sense to add options when we have a mechanism for specifying arbitrary groups of files. I'm not sure how useful it will be outside purge to specify just regular files or just directories, but I _can_ see a use case for e.g. specifying all executable files.
