Syck is now checked into Ruby CVS.  You'll see it appear in the
Ruby 1.8.0 release forthcoming.  I'd like to propose Syck for
inclusion in PHP and Python as well, since both extensions are
coming along nicely.  Once YAML finds acceptance in these
communities, open source scripting languages will have an
asset not found elsewhere.

Plus, I think we'll save a lot people from writing parsers.  And
consequently, massive regular expressions.

I feel there are great possibilities for YAML and Python, since
they share indentation for scoping.  If the YAML document separator
('---') became a Python construct, you could perform assignment with
YAML rather than Python constructs.

So check YAML out.  The best place to start is the Cookbook.
