SYNOPSYS

       vos_import PATH

       vos_import DIR_PATH USERNAME

DESCRIPTION

       This tool imports external data on the VOSpace file catalog.

       This tool recursively imports nodes on the VOSpace file catalog.

       Only one parameter is required:

       PATH

           the file/directory physical path. It can be a file or a 

           directory.

           If the path is a directory, the command will scan it 

           recursively.

       DIR_PATH:

           the physical path of a directory located within the user directory

           at a given mount point.

       USERNAME:

           the username used for accessing the transfer node.

EXAMPLE

      The following command will import recursively all the nodes contained

      in 'mydir' on the VOSpace for the 'jsmith' user:

      # vos_import /mnt/storage/users/jsmith/mydir jsmith   

    """)

# Create new AMQPClient object

else:

    vosImportCli.help()

# Check the parameter passed by the user

#if os.path.exists(path):

vosImportCli.load(path, username)

#else:

#    vosImportCli.help()
