Something like this (or a stat() equivalent) would be good. I'm trying 
to remember if there was a good reason that this wasn't done before.

> 2) Using error codes instead of error messages

Yes...the current system annoys me really badly, so I'll be considering 
how to change that.

This is planned.

> 4) Support for ISO images

That's...intriguing. I'll have to look at the ISO9660 spec and see how 
much work this would be, though.
