Description:

Syck is an extension for reading and writing YAML swiftly in popular scripting
languages. As Syck loads the YAML, it stores the data directly in your
language's symbol table. This means speed. This means power. This means Do not
disturb Syck because it is so focused on the task at hand that it will slay you
mortally if you get in its way.

From http://yaml.org:
YAML(tm) (rhymes with "camel") is a straightforward machine parsable data
serialization format designed for human readability and interaction with
scripting languages such as Perl and Python. YAML is optimized for data
serialization, configuration settings, log files, Internet messaging and
filtering.

The syck-php package contains the syck php extension.
