AddToFunc StartFunction
+ Test (F fvwm-functions-starters-games.fvwm) AddToMenu Main "Games" PopUp Games


... doesn't work

However, I can't tell if the test is successful or not.  Yet


AddToFunc StartFunction
+ AddToMenu Main "Games" PopUp Games


... doesn't work, either.  Otherwise, how would I make sure that the
function that adds the menu entry is being exectued only once, and at
the right time?
