Subject: [ANN] YAML.rb 0.49.1 -- Perfecting the parser, new merge indicator, base60

YAML.rb 0.49.1 now out.  [http://yaml4r.sf.net/]

This version includes a few fixes to work better with Windows and
various versions of Ruby.  We're parsing better than ever.  And I've
even got a few new features for ya.

  - The merge indicator is now '<<'.  If you're not familiar with
    this indicator, that's because it was quietly introduced in
    0.49.  A merge will mix mapping elements into another mapping:

      mapping:
        name: Joe
        job: Accountant
        <<:
          age: 38

    The above document comes out as a Ruby Hash:

      { 'mapping' =>
        { 'name' => 'Joe',
          'job' => 'Accountant',
          'age' => 38
        }
      }

    As you can see the deeper hash is merged into the hash containing
    the merge key.  This is very useful for inheritance:

      - &ACCOUNTANT
        job: Accountant
        hourly_rate: 150

      - name: Joe
        <<: *ACCOUNTANT

      - name: Mike
        <<: *ACCOUNTANT

    You can mixin multiple mappings as well.  See
    http://yaml.org/type/merge for the full specification in the
    YAML type repository.

  - Base60 added for time and degrees representation.

      the following are equal:
        - 1:30
        - 90
      these two are equal as well:
        - 190:20:30
        - 685230    # = 190 h 20 m 30 s

    This will show up at http://yaml.org/type/int in a few days.

Nice little features long requested on yaml-core.  Enjoy 0.49.1.  Please
contact me with your bug reports and assistance.  I'd like 0.50 to be a
solid package, which is only possible with your kind help.
