I’m using: SWI-Prolog version 8.5.3-41
I haven’t used Prolog for some years and have just build the most recent version.
I noticed that XPCE was missing and after a quick search I found
packages-xpce. README.md tells that instructions for building XPCE can be found in INSTALL.md but that file is missing?
Is XPCE still used or is there an alternative? Where can I find build instructions?
