NAME
     unzck -- decompress a file in the zchunk format

SYNOPSIS
     unzck [-c | --stdout] [--dict] [-v | --verbose] file
     unzck -? | --help
     unzck --usage
     unzck --version

DESCRIPTION
     The unzck utility extracts the original file from a zchunk-compressed one.

     NOTE:  The unzck utility will place the new file without the .zck extension
     in the current working directory, not in the directory where  the	original
     file resides.

     The unzck utility accepts the following optional arguments:

     -c, --stdout
	     Extract  the data to the standard output stream, do not write it to
	     a file.

     --dict  Only extract the zstd compression dictionary.

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

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

     --usage
	     Display brief program usage information and exit.

     --version
	     Display program version information and exit.

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

EXAMPLES
     Create (in the current directory) an uncompressed words file  from  a  com-
     pressed one:

	   unzck /mnt/xfer/words.zck

     Do  not create the words file, but send the contents to the standard output
     stream:

	   unzck -c /mnt/xfer/words.zck
