       fltk - the fast light tool kit

       The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a C++
       graphical user interface toolkit for the X Window System, MacOS(r), and
       Microsoft Windows(r) that supports OpenGL(r).  It was originally
       developed by Mr. Bill Spitzak and is currently maintained by a small
       group of developers across the world with a central repository in the

       FLTK is provides under the terms of the GNU Library General Public
       License, with the following exceptions:

              1. Modifications to the FLTK configure script, config header
              file, and makefiles by themselves to support a specific platform
              do not constitute a modified or derivative work.

              The authors do request that such modifications be contributed to
              the FLTK project - send all contributions through the "Software
              Trouble Report" on the following page:


              2. Widgets that are subclassed from FLTK widgets do not
              constitute a derivative work.

              3. Static linking of applications and widgets to the FLTK
              library does not constitute a derivative work and does not
              require the author to provide source code for the application or
              widget, use the shared FLTK libraries, or link their
              applications or widgets against a user-supplied version of FLTK.

              If you link the application or widget to a modified version of
              FLTK, then the changes to FLTK must be provided under the terms
              of the LGPL in sections 1, 2, and 4.

              4. You do not have to provide a copy of the FLTK license with
              programs that are linked to the FLTK library, nor do you have to
              identify the FLTK license in your program or documentation as
              required by section 6 of the LGPL.

              However, programs must still identify their use of FLTK. The
              following example statement can be included in user
              documentation to satisfy this requirement:

              [program/widget] is based in part on the work of the FLTK
              project (http://www.fltk.org).
