Xgcl software is now available; it provides an interface to X windows
from GCL (Gnu Common Lisp, formerly Austin Kyoto Common Lisp or AKCL).
There is a low-level interface to the Xlib routines, and there is
an easy-to-use interface that provides graphics, menus, and mouse
interaction via functions that are called from Lisp.
Xgcl is built on top of GCL, and it is somewhat larger
(e.g. 6.7 MB for Xgcl vs. 4.9 MB for GCL) because it incorporates
Xlib. To make Xgcl, you must first obtain and make GCL. The code
was written by Gordon Novak, Hiep Nguyen, and William Schelter.
The file is called xgcl-2.tgz . Xgcl and GCL can be FTP'd from:
math.utexas.edu pub/gcl
ftp.cli.com pub/gcl
cs.utexas.edu pub/novak/xgcl (Xgcl file only)
http://www.cs.utexas.edu/users/novak (Xgcl file only)
Put the xgcl-2.tgz file in the same directory as gcl-1.1.tgz .
Uncompress it with: gzip -dc xgcl-2.tgz | tar xvf -
Then see the README in the directory xgcl-2.
