The file dgux-5.4R3.10-cdrom.tar.gz is a gzipped tar file containing the following files: python-dgux-dist/ README - a brief note about the distribution python - Python 1.3 image btree.py - my favorite Tkinter demo thingy lib.tar.Z - necessary libraries, in case you don't have them The image may be run from anywhere, but the libraries will need to be in the places mentioned in the README file. Read it. cheers Ross Andrus June 1996
