* Extensively documented.

Goals:
* Sharpen low-level programming skills.
* Familiarize with amd64 architecture details.
* Have fun along the way!

# Instructions for running the utilities

## c_toolchain utility docker image

This is the consistent C toolchain environment, containing all the tools needed to run and develop the project.

Dockerfile: `dockerfile.c_toolchain`
Run the docker-compose command to get a `bash` shell that is bound to the `dmzOS` directory:
```docker
docker-compose run --rm c_toolchain
```

Any changes in the container `dmzOS` directory will be reflected in the local `dmzOS` directory.

The image contains `indent` and `clang-format` as `C` code formatters.

A .vimrc file is automatically part of the image, and it contains a rule to make vim run the following formatting command on buffer save:
```bash
indent -kr -ts4 %
```
This is using the Kernighan and Ritchie code styling, as well as identations with 4 spaces.

If you want to use your own `.vimrc`, please replace the existing `.vimrc` file inside the `config` directory with it.
