   39/** <module> Hook XPCE based graphics tools into IDE
   40
   41Loading this file enables the graphical  frontends for the online manual
   42and profiler. This file is normally   loaded from swipl.rc (swipl-win.rc
   43on Windows); the file that makes XPCE known to Prolog.
   44
   45This file uses call/1 to call the real work to avoid undefined predicate
   46messages when using make/0 (calling list_undefined/0).
   47
   48Since  the  introduction   of   the    more   advanced   autoloader   in
   49library(prolog_autoload), using call/1 no longer   suffices to stop this
   50file from being loaded.
