Multiline strings in YAML

If you're using Middleman data files (which are awesome), you might run into an issue where you want to store text intended for Markdown processing within a .yaml file. To do so, just use |:

widget:
  content: |
    # This is some markdown content in YAML that will be output as an <h1>.

    This will be output as a paragraph tag.

    So will this!

Technically you can use > instead of |, but > does not output linebreaks when the YAML is parsed, which can create issues when the text is processed through Markdown.
