Welcome to Udanax Green!

QUICK START: just type "make demo".  Read on for details...

The software consists of two main parts: the back-end and the front-end. (Nowadays people commonly refer to these as the server and client.)

The back-end is written in C. The source code is in the green/ directory. To build the executable, go into the green/ directory and run "make". It should compile painlessly on any Linux system. For some other systems, you may need to edit be_source/Makefile to choose the appropriate options to the C compiler.

The front-end is written in Python. It is located in the pyxi/ directory. It should run on any system that has Python 1.4 or better with Tcl/Tk support. When you start Pyxi, it will also run the back-end in the be/ subdirectory. The set of documents you view and edit is stored in a single file called an enfilade file, located at be/enf.enf. If you want to save a snapshot of the enfilade or replace it with another, just copy or replace this file. If be/enf.enf is not present, Pyxi will start up by copying in the sample dataset, which contains some instructions and the Declaration of Independence.

The back-end has a few known bugs, which have surfaced during testing with the Pyxi front-end. However, it should be stable enough for you to try it out and get a feel for what the powerful data structures and algorithms in the server can do. All of the back-end code was part of the Xanadu hypertext project, and is now released to the public as open source.

This distribution was released on 2 September 1999.
