zck -? | --help | --usage | --version
DESCRIPTION
The zck utility creates a new zchunk file from the data in the specified input file.

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
