Module PCE. This module defines the core of XPCE. It is designed in
such a way that it may be compiled using the SWI-Prolog qcompile/1
compiler, which makes XPCE an autoloadable module of SWI-Prolog.
Various things are Prolog-implementation specific in this module and
therefore each Prolog system will require a different version of this
module.
This module only defines some paths, some things to make the .qlf
compiler work on it and finally it just loads the XPCE modules and
reexports the content of these files.
