     The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
     C++  graphical  user interface toolkit for the X Window Sys-
     tem,  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 US.

     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  con-
          tributed  to  the FLTK project - send all contributions
          to "fltk-bugs@fltk.org".

          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 pro-
          vided 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).
