| 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.""" |
