Subject: [ANN] PyYAML-3.07: YAML parser and emitter for Python

 Announcing PyYAML-3.07

A new release of PyYAML is now available:


* The emitter learned to use an optional indentation indicator
  for block scalar; thus scalars with leading whitespaces
  could now be represented in a literal or folded style.
* The test suite is now included in the source distribution.
  To run the tests, type 'python test'.
* Refactored the test suite: dropped unittest in favor of
  a custom test appliance.
* Fixed the path resolver in the LibYAML-based dumper.
* Forced an explicit document end indicator when there is
  a possibility of parsing ambiguity.
* More improvements: the package should be usable
  when any combination of setuptools, Pyrex and LibYAML
  is installed.
* Windows binary packages are built against LibYAML-0.1.2.
* Other minor fixes and improvements (Thank to Ingy dot Net
  and Andrey Somov).

About PyYAML

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.
