Hi there  
I am confident I can write functions in Julia ( thanks to the wonderful book ( the julia language handbook by George Root) but I am NOT confident I know how to tie all the functions together in the same manner I would a python program. Normally I would set up a cronjob which runs a script that has a

```julia

def main():
   # read csv from source curl "https://www.hedginglab.com/api/beta/v1/hvi_daily/?apikey=demo=csv"

if __name__ == " __main__":
    main()

```

which would act as the startup script thus the controller. Can someone point me at any example that shows a recommended approach to this using julia please?  
thank you
