 ## Example Programs
 
-* example_1.py - This program demonstrates a synchronous approach 
-to accomplishing tasks. The worker can't delegate
-any tasks and completes them all one after another.
-* example_2.py - This program demonstrates a synchronous approach 
-to accomplishing tasks. The worker can't delegate
-any tasks and completes them all one after another.
-In this version there is a second worker created,
-but the two workers aren't cooperating with each
-other.
-* example_3.py - This program demonstrates a synchronous approach 
-to accomplishing tasks. In this version there is a 
-second worker created, and the workers can delegate 
-back to the control loop to cooperate with each other,
-but there isn't any net benefit because the tasks
-are still running synchronously.
-* example_4.py - This program demonstrates a asynchronous approach 
-to accomplishing tasks. In this version there is a 
-second worker created, and the workers can delegate 
-back to the control loop to cooperate with each other.
-In this version the tasks are asynchronous, so the
-workers run concurrently.
-* example_5.py - This program demonstrates a synchronous approach 
-to accomplishing tasks. In this version there is a 
-second worker created, and the workers can delegate 
-back to the control loop to cooperate with each other,
-but there isn't any net benefit because the tasks
-are still running synchronously. The tasks for this demo are getting the contents of webpages.
-* example_6.py - This program demonstrates a asynchronous approach 
-to accomplishing tasks. In this version there is a 
-second worker created, and the workers can delegate 
-back to the control loop to cooperate with each other.
-In this version the tasks are asynchronous, so the
-workers run concurrently. The tasks for this demo are getting the contents of webpages.
-* example_7.py - This is a bonus example program demonstrating a asynchronous approach to accomplishing tasks. In this version there is a second worker created, and the workers can delegate 
-back to the control loop to cooperate with each other.
-In this version the tasks are asynchronous, so the
-workers run concurrently. The tasks for this demo are getting the contents of webpages and reading files
