This file initialises XPCE, the SWI-Prolog native GUI. XPCE is initialised if one of these conditions is true.

• The Prolog flag xpce is true
• There is a GUI. See has_display/0 below. In this case, XPCE is loaded if the Prolog flag xpce is true. Otherwise it is setup to be loaded lazily if one of the GUI IDE tools is invoked.

The source-location of this file is packages/xpce/swipl/swipl-rc. It is installed as <plbase>/<exe-base>.rc, where <exe-base> is swipl-win to associate with the SWI-Prolog gui application on Windows and swipl on Unix/X11 platforms.
