+ * This function adds a stanza handler to the connection. The
+ * handler callback will be called for any stanza that matches
+ * the parameters. Note that if multiple parameters are supplied,
+ * they must all match for the handler to be invoked.
+ *
+ * The handler will receive the stanza that triggered it as its argument.
+ * The handler should return true if it is to be invoked again;
+ * returning false will remove the handler after it returns.
+ *
+ * As a convenience, the ns parameters applies to the top level element
+ * and also any of its immediate children. This is primarily to make
+ * matching /iq/query elements easy.
+ *
+ * The options argument contains handler matching flags that affect how
+ * matches are determined. Currently the only flag is matchBare (a
+ * boolean). When matchBare is true, the from parameter and the from
+ * attribute on the stanza will be matched as bare JIDs instead of
+ * full JIDs. To use this, pass {matchBare: true} as the value of
+ * options. The default value for matchBare is false.
+ *
+ * The return value should be saved if you wish to remove the handler
+ * with deleteHandler().
+ *
+ * Parameters:
+ * (Function) handler - The user callback.
+ * (String) ns - The namespace to match.
+ * (String) name - The stanza name to match.
+ * (String) type - The stanza type attribute to match.
+ * (String) id - The stanza id attribute to match.
+ * (String) from - The stanza from attribute to match.
+ * (String) options - The handler options
+ *
+ * Returns:
+ * A reference to the handler that can be used to remove it.
