How to run some clean up code after all the tasks been executed?

[GeorgeX]

Suppose that I have to create an client for some tasks, and it can be very expensive to create the client. After the execution of all the tasks, the `client` better to be closed. but I haven't find a way to do that.

I found the "teardown" keyword. but it looks like it will run for each task/sub-task. 

tried the following code: 

 with get_some_expensive_client(**) as some_client:

        DoitMain(ModuleTaskLoader({

            'task_xyz': func_xyz

        })).run(sys.argv[1:])

It seems working, but the issue is that the client is kind of a global variable. Is there a way for the task function to take an argument? then the `client` can be passed in to the task.

Never mind. There is some simple work around. Thanks for the nice tool: doit!
