DESCRIPTION
     The  zckdl  utility attempts to download a zchunk file in an optimized way,
     taking into consideration the chunked structure.

     The zckdl utility accepts the following optional arguments:

     --fail-no-ranges
	     If the server does not support ranges, fail instead of  downloading
	     the whole file.

     -q | --quiet
	     Quiet operation; only display warning and error messages.	If spec-
	     ified twice, only display error messages.

     -s | --source
	     Specify  the  file to use as a source with the premise that most of
	     the chunks in the downloaded file will be the same.

     -v, --verbose
	     Verbose operation; display some diagnostic output.

     -?, --help
	     Display program usage information and exit.

     --usage

     --version
	     Display program version information and exit.

EXIT STATUS
     The zckdl utility exits 0 on success, and >0 if an error occurs.
