 Pass in as query parameters of any request:

 Remember to URL encode any special characters, which are often seen in passwords and to
 also enable SSL support.

+By calling GET /login?login=fred@example.com&password=ilovecheese, you get back
+a C<token> value which can then be passed to each subsequent call as
+authentication. This is useful for third party clients that cannot use cookies
+and do not want to store a user's login and password in the client. You can also
+pass in "token" as a convenience.
