Keywords: networking, GUIs.

XPCE/SWI-Prolog for PC/Linux is now available. XPCE is a symbolic object-oriented interface toolkit for symbolic programming languages. XPCE offers a high level of abstraction for communication with X11, Unix processes, Unix networking facilities (sockets) and Unix files. XPCE's built-in classes (about 150) are mostly written in the C language. The XPCE/Prolog interface allows the user to create instances of these classes and manipulate instances. The user can also create new XPCE classes from Prolog.

XPCE's window related classes provide various styles of menu's, primitive graphical objects, compound graphical objects and Emacs oriented programmable text manipulation windows.

The distribution includes various demo programs, including:

PceDraw: a (diagram) drawing tool
Ispell: graphical interface for Unix ispell
Kangaroo: Jumping kangaroos (animation demo)
PceEmacs: Epoch like editor with modes for Prolog, C, LaTeX, the Unix manuals, gdb, etc.
PceManual: Online hyper-text like manual for XPCE itself
