Consider verbose 'usage' messages for infrequently used scripts

This issue is much broader than that.

This is for _anything_ you don't use all the time at high frequency. And then, you have the other way: in the routine, you'll mechanically make mistakes without even noticing.

And you'll discover that some people hardly forget anything compared to others, and that over very long periods of time, including the most unimportant things. Some, to a scary level.
