[Yaml-core] YAML.pm implementation is complete

[Brian I. <in...@tt...>]

I have completed the Perl YAML.pm that I will be using for demoes at the
O'Reilly Open Source Convention next week. It is available at:

    http://ttul.org/~ingy/YAML-0.12.tar.gz

It is not a full implementation of the spec, but does a fairly good job
of the most important features. I added a lot of the new cleaner syntax
we came up with this week. I even added ':' bullets for all list items.
I actually like them.

I'm attaching some sample output.

One thing I noticed is that an empty string gets coded as:

    foo: ""
    bar: value

Which is fine, but some people might want:

    foo:
    bar: value

Well, it turns out that this does the same thing because it is a empty
block. Pretty neat.

Cheers, Brian
