Output YAML data anywhere in WordPress.
Download and install (use the ZIP file for now). Then move the yaml folder to wp-content/uploads, and add the following shortcode to any post or page:
[dataloader file="blogroll.yml" tpl="blogroll.php"]
The shortcode accepts, no, requires, two arguments: a YAML file, and a template file. The YAML file must live in wp-content/uploads/yaml, and the template must be placed in wp-content/uploads/yaml/templates. If your WordPress install uses a custom uploads location, adjust these paths accordingly.
Then, play around with the yaml folder's contents and adjust your shortcode(s) accordingly. (Protect your YAML and PHP template files as you see fit.)
