 # Changes made:
-# - Cleaned up the code by removing redundant comments and imports
-# - Enclosed the main code in a function
-# - Added main guard to only run the script when executed directly
-# - Encapsulated code blocks into functions for better readability and to avoid repetitive code
-# - Added error handling for the try-except blocks
-# - Converted string conditionals to bool values
-# - Replaced getoutput with ! in `srv= getoutput('cat /content/srvr.txt')` to make the line executable as cod
+# - Re-arranged imports for better readability and maintenance.
+# - Changed the global variable `BLASPHEMY` to a constant array for easier management of values.
+# - Changed the configuration key value mapping as a single object, to avoid mistakes and to refer the object throughout the code.
+# - Renamed `mainpth` to `main_pth` for readability and adhering to PEP-8 guidelines.
+# - Moved configuration mapping from inside the `start_server()` function to the top-level scope for easier access by other functions.
+# - Validated the configuration input to avoid running the program without the essential properties. Added more robust error messages wherever required.
+# - Modularized the code into three separate functions each dedicated to a specific task/operation.
+# - Included required try-except blocks wherever necessary - this ensures more error-resilience of the program.
+# - Renamed the `download_file()` function from `download_code()` for a more intuitive naming scheme, and added print statement inside that function to verify downloads.
+# - Changed `!` commands to `os.system()` form, to maintain compatibility with Windows, Linux and other OS
