+SemanticScuttle API
+===================
+
+SemanticScuttle tries to implement the delicious API v1 as closely as sensible.
+
+Where it makes sense and the delicious API just does things plainly wrong
+(i.e. when returning a wrong status code on an error), we do it better.

  * The delicious API behaves like that:
- * - returns "done" even if the bookmark doesn't exist
- *   - we do it correctly
  * - does NOT allow the hash for the url parameter
  * - doesn't set the Content-Type to text/xml
  *   - we do it correctly, too
