Documentation of FileUtils is very unclear on how errors are handled.

Looking at the documentation at http://ruby-doc.org/stdlib/libdoc/fileutils/rdoc/classes/FileUtils.html on "cp_r" you can see that error handling isn't mentioned at all, and you can't see how errors are handled from the attached source either. I had to follow this path to finally find out how errors were handled:

cp_r -> copy_entry -> Entry_.traverse -> preorder_traverse
