# magic program > I don't know what's this shitty program doing. I was forced to write it. `./main.py` is named as PROGRAM ALPHA, and `summerize-part-list/main.py` is named as PROGRAM BETA. (Because the program sucks, and too difficult to name them) Firstly, run PROGRAM BETA to generate one dir (with some pdf-s), one sheet (as the input of ALPHA), and another csv (containing errors). Then run ALPHA to get the final result.
