+    XEP-0066: Out-of-Band Data
+
+    Out-of-Band Data is a basic method for transferring files between
+    XMPP agents. The URL of the resource in question is sent to the receiving
+    entity, which then downloads the resource before responding to the OOB
+    request. OOB is also used as a generic means to transmit URLs in other
+    stanzas to indicate where to find additional information.
+
+    Also see <http://www.xmpp.org/extensions/xep-0066.html>.

+    Methods:
