What is libyaml-perl
libyaml-perl is:
YAML is a generic data serialization language that is optimized for human readability. It can be used to express the data structures of most modern programming languages (including Perl, of course). YAML supports Unicode and there are implementations of the parser in many different languages, making it a rather portable serialization format.
Please note that the YAML module is currently a deprecated implementation in Pure Perl, which is probably slow on your system.

For now, YAML::Any is a module provided for this purpose, which simply selects the best YAML implementation available.
