# To make sure the Python virtual environment will be placed in the

# Get program help:
#  make run

# Run the program:
#  make -- run --arg-name arg-value ...

# Rules:
#  1. -- after make is required!
#  2. Omit the = after the argument names
#  3. If arg-value contains spaces, surround arg-value with "' and '"

 # If the first argument is "run", package arguments into RUN_ARGS
