All code is properly documented with extensive inline and definition comments.

Installation

No specific installation instructions are required. Just install a Python 3 version.

Running

To run a specific challenge, you may type the following command (where N is a number between 1 and 10, specifying the challenge number):

python client_N.py

To run and automatically submit a challenge's flag (bonus task),you may run the following command (replacing incognito.guy with the desired username, and N with the challenge number):

python submit.py -u incognito.guy -c N

Alternatively, to run and submit all challenges, you may omit the -c flag (it will execute challenges 1 to 10):

python submit.py -u incognito.guy

These are all the available options for the scorebot submitter:
