Thank you very much for pointing me to the -X option which I had not
noticed before.

Why is it hard to fix if -X actually exists? Why not have -X as default?
Is the current default behaviour good for anything?

I still suggest putting some semantical description into the
hierarchical libraries extension document, so that people like me do not
jump to wrong conclusions because of the similarity with directory
