I've done a lot of stuff to that code that you send.
I'm doing some more small changes and will send it very soon.

I don't know if you read that comments in the code I already send you, but I
implemented a lot of that stuff.

I would have to warn you that I did a lot of smaller, not_so_important changes
too. For example, I changed some of the variable names which I found a bit 
confusing and also did some beautification of the code. :)
So you will have to tell me if you mind me doing stuff like that, so I could 
know for the future. :)

About that error stuff...

I implemented _some_ error checking in _a few_ subroutines.
It's not much and it's there just for as an example.

It looks like:

        if (! chdir $dir) {
                return if error($elt, "Unable to change directory to $dir.\n");

which is similar to what you proposed in one of your messages.

But I'll send you the code soon, so you can see it yourself.
