Copies a file system entry src to dest. If src is a directory, this method copies its contents recursively. This method preserves file types, c.f. symlink, directory… (FIFO, device files and etc. are not supported yet)
Both of src and dest must be a path name. src must exist, dest must not exist.
If preserve is true, this method preserves owner, group, and modified time. Permissions are copied regardless preserve.
If dereference_root is true, this method dereference tree root.
If remove_destination is true, this method removes each destination file before copy.
