  Consistent Overhead Byte Stuffing (COBS)
  ========================================
  
  Python functions for encoding and decoding COBS.
  
  -----
  Intro
  -----
  
  Functions are provided for encoding and decoding according to
  the basic COBS method.  The COBS variant "Zero Pair Elimination" (ZPE)
  is not implemented.
  
  A pure Python implementation and a C extension implementation
  are provided. If the C extension is not available for some reason,
  the pure Python version will be used.
  
  This is fully implemented for Python 2.6. It is partially
  implemented for Python 3.1--the C extension is working, but the
  pure Python code is not.
