Code not making up the core library is located in `auxiliary/<auxiliary_name>.<hpp/cpp>`. These are optional extensions or tools for the library.
**TODO : Right now the library is not finished, as such the first self-hosting iteration is still WIP**
Both libraries use *pre-generated* (self-hosting I guess) version of the library to then generate the latest version of itself.

The library has its code segmented into component files, use it to help create a derived version without needing to have to rewrite a generated file directly or build on top of the header via composition or inheritance.
