5LONG_DESCRIPTION = """\
6YAML is a data serialization format designed for human readability and
7interaction with scripting languages.  PyYAML is a YAML parser and
8emitter for Python.
9
10PyYAML features a complete YAML 1.1 parser, Unicode support, pickle
11support, capable extension API, and sensible error messages.  PyYAML
12supports standard YAML tags and provides Python-specific tags that allow
13to represent an arbitrary Python object.
14
15PyYAML is applicable for a broad range of tasks from complex
16configuration files to object serialization and persistance."""
