# 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.
