+Subject: [PATCH 1/2] Support asynchronous calls (#58)
+
+Added support for asynchronous calls of methods. A method is called
+synchronously unless its callback parameter is specified. A callback
+is a function f(*args, returned=None, error=None), where args is
+callback_args specified in the method call, returned is a return
+value of the method and error is an exception raised by the method.
+
+Example of an asynchronous call:
+
+def func(x, y, returned=None, error=None):
+  pass
+
+proxy.Method(a, b, callback=func, callback_args=(x, y))
+
+Upstream-Status: Cherry-pick [https://src.fedoraproject.org/cgit/rpms/python-pydbus.git/]
