class Fltk(Package):
    """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.
