Yes, I know and I have noticed ...

I believe a reminder line could be instructive for the example -
at last for the longer ones. For the IO Example which has a main() funcation,
I believe not having it in there is a serious problem.

In pyme, which was certainly done by a caring developer,
the examples all miss the version check.
