The syck extension is a binding to the Syck library which facilitates
YAML parsing.

YAML(tm) (rhymes with "camel") is a straightforward machine parsable
data serialization format designed for human readability and
interaction with scripting languages. YAML is optimized for data
serialization, configuration settings, log files, Internet
messaging and filtering.
