Syck is, at present, the de facto YAML library for Ruby. 
<http://whytheluckystiff.net/syck/>

YAML is a serialization language.  Hopefully readable.  Sensible to the 
parser in some eyeballs. <http://yaml.org/>

Syck 0.55 patches some memory leaks and parse errors.  Loading of 
objects is now much smoother.  Support for using your own 
yaml_initialize or yaml_new methods.  (See lib/yaml/rubytypes.rb for 
examples.)  I'd say typing is done at this point.

A bit more debugging and I will merge with Ruby CVS.
