You should definitely check out my other SDL-related project called [SDL Framework](https://github.com/Lauchmelder23/SDLFramework). It does not use this wrapper library but it sets up some interfaces you can derive from to have a fully-functional and fully-customizable SDL MessageLoop with no effort!
While SDL2 is a great library to handle graphics and audio, it can be laborious to get a quick program up and running. SDLU tries to solve that by implementing objects that sit on top of native SDL2 functions and act as a sort of API between your program and SDL2. However it still allows the user to access SDL2 objects like `SDL_Window` and use them in native SDL2 functions. SDLU also contains primitive shapes that can be quickly set up and rendered onto the screen.
This library aims to minimize the work needed to setup a simple project.
The source code is annotated with doxygen comments. Simply run doxygen on the SDLU directory to generate the documentation for this library. An example project can also be built (Set the `ENABLE_EXAMPLE` flag in CMake), which implements a simple program using the SDLU library.
