Update documentation manuals.
    
        - Use my personal name in copyright note. It is a contradition to
          release a work using someone else name. In this case The CentOS
          Project is an entity, a group of persons that are not working in
          this document at present time.
          
          It is my wish that this document be maintained by CentOS
          Community as free document (see GFDL license) but until that day
          become true, I keep working and signing my work with my personal
          name on copyright notes, in order to release it using free
          licenses like GPL and GFDL.
    
          When this document be maintained by CentOS Community, there will
          be two copyright notes in this document. One for the time I
          worked on it, and another for the time the CentOS Community
          works on it. At that time, I hope to be inside CentOS Community
          once again, and so help to build a Community that persist longer
          than our lives do. This way the document will be safe on it, and
          somehow, do we all too.
