Dear Ryan,
thanks. Your answers helped me a lot. May I ask some further
questions to ensure I got everything right?

At this time my reps will only be used by myself.

Does that mean, that subversion does recognize which data is binary
and which can be understood as text? Or do have to tell subversion
what is what?

And that script would generate the PDF file on checkout? I'm not sure
if I understood this point.

Perhaps sometimes it is easier to check out the PDF files only, e.g.
to print them without having to typeset them.

I'll try that.

Sounds good. I'll try that.
Thanks again.
