It's not.  It's mostly a subset, but there may be some small departures
from the spec as well.

Cool.

I recommend replicating the PyYaml development methodology more than I
recommend porting the PyYaml code itself.  Basically, when I developed
PyYaml, I started by implementing a very bare bones YAML, with just
enough functionality to bootstrap a testing suite, then I started
working through examples in the spec and tried to make them load.

The hardest part of writing a YAML, IHMO, is getting the indentation
worked out, so you might want to read PyYaml/yaml/stream.py for
inspiration.  (It may very well be inspiration for what *not* to do, but
I won't be offended. :)  Everything else is basically a simple matter of
programming.

Can you give a little more background on why you're starting with
PyYaml?

Cheers,
