Subject: Update `trunk/Scripts/centos-art.sh' file:


    - Update comments.

    - Start using `declare -xr' to define variables.

    - Introduce CLI_WRKCOPY variable to store the working copy
      absolute path.

    - Verify the working copy directory. Be sure it is
      `/home/centos/artwork'.  Otherwise, end the script execution.
      We cannot continue if the working copy is stored in a place
      other than `/home/centos/artwork'. This restriction is what let
      us to reuse contents using absolute paths inside a distributed
      environment like that one provided by The CentOS Artwork
      Repository.
