+----------------
+This module demonstrates the use of asyncio to handle asynchronous and blocking
+functions in Python. The module contains three functions: a blocking function
+that simulates a long-running process with `time.sleep`, an asynchronous
+function that demonstrates asyncio's sleep, and a main function that runs
+both the blocking and async functions concurrently using a ThreadPoolExecutor 
+for the blocking function.
