    (description "FLTK is a C++ GUI toolkit providing modern GUI functionality
without the bloat.  It 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.")
