 Nowadays all these dependencies can be found in PyPI, so it's not a big problem to meet them. Indeed, after a plain "pip install," you can already call the "neurodamus" entry point and inspect the usage.
 However, as mentioned, without a compiled model for Neuron, there's nothing much it can do. More on that later.
