libyaml-pp-perl binary package in Ubuntu Jammy amd64

 YAML::PP is a modern, modular YAML processor.
 .
 It aims to support YAML 1.2 and YAML 1.1.
 .
 YAML is a serialization language. The YAML input is called "YAML Stream". A
 stream consists of one or more "Documents", separated by a line with a
 document start marker '---'. A document optionally ends with the document end
 marker '...'.
 .
 This allows one to process of continuous streams additionally to a fixed
 input file or string.
 .
 The YAML::PP frontend will currently load all documents, and return only the
 last if called with scalar context.
 .
 The YAML backend is implemented in a modular way that allows one to add
 custom handling of YAML tags, perl objects and data types. The inner API is
 not yet stable.
