 Description
 ---
-This tool of a very unimaginative name is mainly intended to test implementation of [Force Feedback](https://en.wikipedia.org/wiki/Haptic_technology) on Linux systems. It has a Qt5-based GUI that allows the user to set up parameters of the effects and play them back on their devices. Only Linux Force Feedback API is supported at the moment. Support for other interfaces ([SDL2](https://www.libsdl.org/), [DirectInput](https://msdn.microsoft.com/en-us/library/windows/desktop/ee418273(v=vs.85).aspx)) might be added in the future.

-Note that some Linux distributions may provide `qmake-qt5` and `qmake-qt4` to target different version of the Qt framework. In such a case run `qmake-qt5` instead of qmake.
+Note that at least CMake 2.8.13 is required. SDL2 header files and PkgConfig are required to enable SDL2 support.
