+features
+--------
+
+- Very fast, small and efficient.
+- Uses only integer math.
+- No dependencies (uses only stdint standard library).
+- Single header, KISS.
+- Advanced rendering of variable height floor and ceiling.
+- Textured walls and floor.
+- Depth information (for fog).
+- Camera shearing (looking up/down).
+- Camera movement with collisions.
+- Support for opening door.
+- Pure C, tested to run as C++ as well.
+- Optional framework functions that handle the whole rendering.
+- Still flexible -- pixels are left for you to draw in any way you want.
+- Tested on multiple platforms (PC, Arduboy, Pokitto).
+- Many compile-time options to tune the performance vs quality.
+- Well commented code.
+
+**NOTE**: Backwards compatibility isn't a goal of this libraray. It is meant to
+be an as-is set of tools that the users is welcome to adjust for their
+specific project. So new features will be preferred to keeping the same
+interface.
+
+TODO
+----
+
+- Transparency (conditional ray passing through).
+- Doors in the middle of squares.
+- Rolling doors for `RCL_renderComplex`.
+- Possibly merge all rendering functions into one.
