Can someone explain me exactly (better if with examples) the meaning of the dereference_root option in FileUtils.cp_r and in other class method of the same class?
Thank you in advance.

This program is free software. You can distribute/modify this program under the same terms of ruby. Namespace for several file utility methods for copying, moving, removing, etc. The options parameter is a hash of options, taken from the list :force, :noop, :preserve, and :verbose. :noop means that no changes are made. The other three are obvious.

It applies only if your source file/directory is symbolic link. If it is and you specify this option, then FileUtils.cp_r will follow this link and copy the original files otherwise you will get just a copy of the symlink.
But this doesn't apply recursively. So if you will have other symlinks inside your source folder they will be just copied as is, without 'dereferencing'.
