        Procrastinate is an open-source Python 3.6+ distributed task processing
        library, leveraging PostgreSQL to store task definitions, manage locks and
        dispatch tasks. It can be used within both sync and async code.
        
        In other words, from your main code, you call specific functions (tasks) in a
        special way and instead of being run on the spot, they're scheduled to
        be run elsewhere, now or in the future.
        
        Here's an example:
        
        .. code-block:: python
        
            # mycode.py
            import procrastinate
        
            # Make an app in your code
            app = procrastinate.App(connector=procrastinate.AiopgConnector())
        
            # Then define tasks
            @app.task(queue="sums")
            def sum(a, b):
                with open("myfile", "w") as f:
                    f.write(str(a + b))
        
            with app.open():
                # Launch a job
                sum.defer(a=3, b=5)
        
                # Somewhere in your program, run a worker (actually, it's often a
                # different program than the one deferring jobs for execution)
                app.run_worker(queues=["sums"])
        
        The worker will run the job, which will create a text file
        named ``myfile`` with the result of the sum ``3 + 5`` (that's ``8``).
        
        Similarly, from the command line:
        
        .. code-block:: bash
        
            export PROCRASTINATE_APP="mycode.app"
        
            # Launch a job
            procrastinate defer mycode.sum '{"a": 3, "b": 5}'
        
            # Run a worker
            procrastinate worker -q sums
        
        Lastly, you can use Procrastinate asynchronously too:
        
        .. code-block:: python
        
            import asyncio
        
            import procrastinate
        
            # Make an app in your code
            app = procrastinate.App(connector=procrastinate.AiopgConnector())
        
            # Define tasks using coroutine functions
            @app.task(queue="sums")
            async def sum(a, b):
                await asyncio.sleep(a + b)
        
            async with app.open_async():
                # Launch a job
                await sum.defer_async(a=3, b=5)
        
                # Somewhere in your program, run a worker (actually, it's often a
                # different program than the one deferring jobs for execution)
                await app.run_worker_async(queues=["sums"])
        
        There are quite a few interesting features that Procrastinate adds to the mix.
        You can head to the Quickstart section for a general tour or
        to the How-To sections for specific features. The Discussion
        section should hopefully answer your questions. Otherwise,
        feel free to open an `issue <https://github.com/peopledoc/procrastinate/issues>`_.
        
        The project is still quite early-stage and will probably evolve.
        
        *Note to my future self: add a quick note here on why this project is named*
        "Procrastinate_".
