I know I need it if I am to use this library in real world. And I doubt
anyone else has an urge of manually deleting old files.
I can not imagine anyone would opose such a thing. But, then maybe I am

world need - I must be able to see right away a meaningful number for the

Anyway, thanks for your precise and quick response. I've got some direction
now ...
