   \brief Creates an extended namespaces

   This program enables the creation of namespaces exploiting Shared Schema facilities and
   namespaces designated to be used as remote namespaces using Remote CMPI facilities.

   Usage:

        CreateExtNs -n <namespace-name> [ -p <parent-namespace> -l <remote-location> ]

   Where
        -n defines the name of the new nameplates.
                Examples: -n root/test
                          -n root/local

        -p Optionally define the new namespace to share schema data with an exciting parent
            namespace.
                Example: -p root/cimv2

        -l Optionally defines this namespace to be represeting a remote locaton with
           hostname <remote-location>. CMPIRDeamon must be running at this location.
                Example: -l localhost
                         -l hpc4711
