      """FLTK (pronounced "fulltick") is a cross-platform C++ GUI toolkit for
         UNIX/Linux (X11), Microsoft Windows, and MacOS X. FLTK provides
         modern GUI functionality without the bloat and supports 3D
         graphics via OpenGL and its built-in GLUT emulation.
  
         FLTK is designed to be small and modular enough to be statically
         linked, but works fine as a shared library. FLTK also includes an
         excellent UI builder called FLUID that can be used to create
         applications in minutes.
