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."""
