class_docstr: (deprecated) Log producer API which sends messages to be logged
  to a 'consumer' object, which then prints them to stdout,
  stderr, files, etc. Used extensively by PyPy-1.1.
code: def __init__(self, keywords, keywordmapper=None, **kw):
      if hasattr(keywords, "split"):
          keywords = tuple(keywords.split())
      self._keywords = keywords
      if keywordmapper is None:
          keywordmapper = default_keywordmapper
      self._keywordmapper = keywordmapper
  
imports: import py
  import sys
label_desc: Use image node_id 1 to create a new Producer object from inherited base classes: object with example: obj = Producer(keywords, keywordmapper)
