- `.github/` - files and scripts related to the integration of the RGBDS codebase with
GitHub.
* `scripts/` - scripts used by workflow files.
* `workflows/` - CI workflow description files.
- `contrib/` - scripts and other resources which may be useful to users and developers of
RGBDS.
* `zsh_compl` - contains tab completion scripts for use with zsh. Put them somewhere in
your `fpath`, and they should auto-load.
* `bash_compl` - contains tab completion scripts for use with bash. Run them with `source`
somewhere in your `.bashrc`, and they should load every time you open a shell.
- `include/` - header files for the respective source files in `src`.
- `man/` - manual pages.
- `src/` - source code of RGBDS.
* Note that the code unique to each RGBDS tool is stored in its respective subdirectory
(RGBASM's code is in `src/asm/`, for example). `src/extern/` contains code imported from
external sources.
- `test/` - testing framework used to verify that changes to the code don't break or
modify the behavior of RGBDS.
- `.clang-format` - code style for automated C++ formatting with
[`clang-format`](https://clang.llvm.org/docs/ClangFormat.html).
- `CMakeLists.txt` - defines how to build RGBDS with CMake.
- `compile_flags.txt` - compiler flags for C++ static analysis with
[`clang-tidy`](https://clang.llvm.org/extra/clang-tidy/).
- `Dockerfile` - defines how to build RGBDS with Docker.
- `Makefile` - defines how to build RGBDS with `make`.
