| 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 persistance.""" |
