PYTHON VERSION: >
   PyYaml is developed with Python version 2.2.  I can't live 
   without Python 2.2--too many great features.  Please do 
   yourself a favor and upgrade now.  I know the decision to
   only support 2.2 and above may lock out some potential users,
   but I believe it will pay dividends in the future, because
   the version 2.2 features allow cleaner and more expressive 
   code.  I do intend to support version 2.2 for a long time.

DISCLAIMER: > 
   PyYaml is not ready to be used as a robust serialization tool,
   although it is moving in that direction, and you can certainly
   experiment with it.

   You can use it more safely for one-way applications.  You can
   make YAML be an input-tool only, such as for configuration files
   or data-driven programs.  You can also use YAML as an output-only
   tool, for things like logging and debugging.

   You can report bugs to showell@zipcon.net.  As of this writing
   (August 2002), I am actively improving PyYaml.

   The interface for YAML is stabilizing, but it is too early in 
   the life cycle for me to guarantee backward compatibility in 
   future releases.  I recommend wrapping your YAML calls in your 
   own methods, if you are concerned about changing interfaces.
   The basic paradigm of load, loadFile, save, and saveFile 
   shouldn't change, but the way that you customize the loader 
   and parser's behavior may.

SOME KNOWN BUGS/LIMITATIONS:
  - folded scalars can't lead with blank line
  - emitter gives invalid YAML for multi-line scalars starting w/whitespace
  - trailing white space after quotes not ignored
  - support for inlined hashes and arrays very primitize--can't nest
    structures and must use simple scalars
  - specifiers like !str, !int, etc. are ignored
