License      : MIT
Description  : YAML is a data serialization format designed for human readability and
             : interaction with scripting languages.  PyYAML is a YAML parser and
             : emitter for Python.
             :
             : PyYAML features a complete YAML 1.1 parser, Unicode support, pickle
             : support, capable extension API, and sensible error messages.  PyYAML
             : supports standard YAML tags and provides Python-specific tags that
             : allow to represent an arbitrary Python object.
             :
             : PyYAML is applicable for a broad range of tasks from complex
             : configuration files to object serialization and persistance.
