# Anything in the code that needs further attention is marked with the

# to how aircraft are marked with streamers to indicate maintaince is
# required before the plane can fly. Typing 'make preflight' will do a
# check for all RBF tags; thus showing the developer what needs to be
# fixed before the program can be released.
