The Old/Classic Perl YAML Module is a software tool, written in Perl, that allows users to parse and produce YAML documents. This module is considered a classic and is still used for compatibility purposes with older systems.
The rest of the documentation remains largely unchanged, except for the renaming of YAML.pm to YAML::Old. The SYNOPSIS provides an example on how to load a YAML stream of 3 YAML documents into Perl data structures. YAML stands for "Yet Another Markup Language", but it's actually a data serialization language. It's used as an alternative to XML as a serialization format. YAML::Old::Dump is used in the same way as Data::Dumper::Dumper by Dumping the Perl data structures back into YAML.
Overall, YAML::Old is a useful tool for handling YAML in Perl, and the renaming of YAML.pm to YAML::Old provides a clear distinction between the old and new YAML modules. The documentation is clear and concise, and the examples provided give a good understanding of how to use the module.
