=head1    DBobjectdefs

This program module file supports the management of the xCAT data object
definitions.

Supported xCAT data object commands:
     mkdef - create xCAT data object definitions.
     lsdef - list xCAT data object definitions.
     chdef - change xCAT data object definitions.
     rmdef - remove xCAT data object definitions.

If adding to this file, please take a moment to ensure that:

    1. Your contrib has a readable pod header describing the purpose and use of
      the subroutine.

    2. Your contrib is under the correct heading and is in alphabetical order
    under that heading.

    3. You have run tidypod on your this file and saved the html file

        Support for the xCAT defls command.

        Arguments:
        Returns:
                0 - OK
                1 - error
        Globals:

        Error:

        Example:

        Comments:
            Object names derived from -o, -t, w, -a or noderange!
            List of attrs to display is given by -i.
            Output goes to standard out or a stanza/xml file (-z or -x)
