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 persistance."""
