 NAME = 'PyYAML'
 VERSION = '5.4.1'
 DESCRIPTION = "YAML parser and emitter for Python"
 LONG_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 persistence."""
