Pure-ruby YAML parser

Hi,

Is there a pure-ruby YAML parser available? Does it ship with Ruby by
default?

Looking at ruby/lib/yaml.rb, after trying to load the syck.so shared
library, on failure it tries to require ‘yaml/parser’. This seems to be
the pure-Ruby YAML parser. But I can’t find it anywhere in the Ruby CVS.

Thanks in advance!

Regards,

Michael
