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. diff --git a/third_party/python/PyYAML/lib/PyYAML.egg-info/SOURCES.txt b/third_party/python/PyYAML/lib/PyYAML.egg-info/SOURCES.txt new
