I understand you, and this is no personal problem for me, I can read the help. I just thought, once wikipedia.py has its own showHelp(), it would be elegant to handle the problem with that. Not the most important task.
Why would you want a built-in solution? There is a dedicated program to fix this problem on every operating system out there. Why would you want to build something yourself? Especially since a home-made implementation will probably break those programs.
