python3-hiera binary package in Ubuntu Oracular amd64

 Hiera is a key/value lookup tool for configuration data, often used in Puppet
 and created and built to make Puppet better and let you set node-specific data
 without repeating yourself.
 .
 Hiera’s hierarchical lookups follow a “defaults, with overrides” pattern,
 meaning you specify common data once, and override it in situations where the
 default won’t work.
 .
 The hierarchical data can be organised as JSON, YAML, and EYAML files.
 .
 This package installs the library for Python 3 of the hiera bindings to work
 with formatted hierarchical data.
