(synopsis "3D C++ GUI library")
(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.")
