# Checklist for correct CML2
# 1) Have you defined a prompt for each menu, choice_type?
# 2) Have you defined a default for each symbol?
# 3) Have you put 'symbols' keyword before each symbol, menu and choice?


# Important note on derived symbols
# DO NOT place any declaration for derived symbols like normal symbols,
# otherwise the derivation will be silently ignored, and you will be left
# wondering why.
