+ * Name: Ouroboros API
+ * Author: Diftraku <diftraku[at]derpy.me>
+ * Description: Ouroboros-like API for Shimmie
+ * Documentation:
+ *   Currently working features
+ *   <ul>
+ *     <li>Post:
+ *       <ul>
+ *         <li>Index/List</li>
+ *         <li>Show</li>
+ *       </ul>
+ *     </li>
+ *     <li>Tag:
+ *       <ul>
+ *         <li>Index/List</li>
+ *       </ul>
+ *     </li>
+ *   </ul>
+ *   Tested to work with CartonBox using "Danbooru 1.18.x" as site type.
+ *   Does not work with Andbooru or Danbooru Gallery for reasons beyond me, took me a while to figure rating "u" is bad...
+ *   Lots of Ouroboros/Danbooru specific values use their defaults (or what I gathered them to be default)
+ *   and tons of stuff not supported directly in Shimmie is botched to work
