For the Fedora 20 unversioned docdirs change, https://fedoraproject.org/wiki/Changes/UnversionedDocdirs the libwps package will need a fix, as currently it duplicates the documentation from the -doc subpackage in the base package. This is because %doc now picks up files stored in %{_docdir}/%{name}.
The duplicated doc files currently also cause a conflict on e.g. i686, because the noarch -doc package may have been built on a different arch.
