-    Important note to IDE users:
-  ============================================================================
-
-  This file *may* be edited *before* building FLTK with your IDE project,
-  i.e. in /path/to/fltk/ide/<your-ide>/FL/abi-version.h:
-
-    (1) Define FL_ABI_VERSION as described below.
-    (2) Rebuild the entire FLTK library.
-    (3) Optional: install files as usual including THIS file.
-
-  DO NOT edit this file after building the FLTK library, i.e. when this
-  file is already installed in a (system) directory used to build your
-  programs.
-
-  Editing this file w/o rebuilding the entire FLTK library will change
-  the ABI and thus render your programs unusable - they may crash or
-  show other unpredictable errors. You have been warned!
-
-  Define FL_ABI_VERSION as 10x0y for FLTK ABI version 1.x.y .
-  Do NOT define FL_ABI_VERSION if you want the ABI compatible default build.
-
-  ============================================================================
-    End of important note to IDE users.
