+SUMMARY="YAML parser and emitter for Python"
+DESCRIPTION="
+YAML is a data serialization format designed for human readability \

+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.

+SUMMARY="HTTP library with thread-safe connection pooling, file post, and more."
+DESCRIPTION="
+- Re-use the same socket connection for multiple requests
+  (HTTPConnectionPool and HTTPSConnectionPool)
+  (with optional client-side certificate verification).
+- File posting (encode_multipart_formdata).
+- Built-in redirection and retries (optional).
+- Supports gzip and deflate decoding.
+- Thread-safe and sanity-safe.
+- Works with AppEngine, gevent, and eventlib.
+- Tested on Python 2.6+, Python 3.2+, and PyPy, with 100% unit test coverage.
+- Small and easy to understand codebase perfect for extending and building upon.
+  For a more comprehensive solution, have a look at \
+  Requests <http://python-requests.org/> which is also powered by urllib3
