+    :synopsis: Returns system-level server version informations
+
+    The ``_versions`` resource returns a JSON object containing various
+    system-level informations for the running server.
+
+    The literal string ``_local`` serves as an alias for the local node name, so
+    for all stats URLs, ``{node-name}`` may be replaced with ``_local``, to
+    interact with the local node's informations.
