NAME
     zck -- compress a file using the zchunk format

SYNOPSIS
     zck [-D file | --dict=file] [-m chunk | --manual=chunk]
	 [-o file | --output=file] [-s string | --split=string] [-v | --verbose]
	 file
     zck -? | --help | --usage | --version

DESCRIPTION
     The  zck  utility	creates a new zchunk file from the data in the specified
     input file.

     NOTE: If no output file is specified using the -o option, the  zck  utility
     will  place the new file with the .zck extension in the current working di-
     rectory, not in the directory where the original file resides.

     The zck utility accepts the following optional arguments:

     -D, --dict
	     Set the zstd compression dictionary to the specified file.

     -m, --manual
	     Do not do any automatic chunking (implies -s).

     -o, --output
	     Output to the specified file.

     -s, --split
	     Split chunks at the beginning of the specified string.

     -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 zck utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     Create (in the current directory) a zchunk-compressed words.zck file from a
     dictionary:

	   zck /usr/share/dict/words

     The same, but specify an output file:

	   zck -o /tmp/words.txt.zck /usr/share/dict/words

     Generate a zchunk file with chunks separated on HTML sections:

	   zck -s '<h2>' doc.html
