-See [CONTRIBUTING.md](CONTRIBUTING.md)
+ * `f` will be defined in `f.impl`. This file will be shown in the LyX document

+ * The function `void f_demo() noexcept` will be defined in `f_demo.impl`. 
+ * The function `f_test` will test `f` and also call the function `f_demo`
+ * The function `void f_test() noexcept` will be declared in `f.h`
+ * The function `void f_test() noexcept` will be defined in `f.cpp`
+ * The function `f_test` will be called in the `main` function
