 I use the adventofcode.py as a launcher to run the solutions from a file per day with a function per part, the inputs are in a folder named for each day, it's a less sophisticated of the version I saw on this [repo](https://github.com/LinusCDE/AdventOfCode2018).
 
 ```
-$ ./adventofcode.py -h
+$ python -m aoc.aoc -h
 usage: adventofcode.py [-h] [--day DAY] [--part PART]
 
 optional arguments:
   -h, --help            show this help message and exit
   --day DAY, -d DAY     Day of the puzzle to run
   --part PART, -p PART  Part of the puzzle of the day to run
 
-$ ./adventofcode.py -d 1 -p 1
-Day 1 part 1 solution : 435
