Hydra -- A fresh look at configuration for machine learning projects

Your code is more complicated than you think. One of the first things every software developer learns about is the command-line. At its core, the command-line is a list of strings that are typically broken down into flags (e.g., -- verbose) and arguments (e.g., -- port 80). This is enough for many simple applications. You can define 2 to 3 command-line arguments in a command-line interface (CLI) parsing library, and you are done.
