ALT Demo Version 0.1
--------------------

This distribution contains a simple graphical demonstration program
for Dave Compton's Application-Level Toolkit (ALT), built on top of
the NewsML Toolkit.  This program interactively uses the following ALT
features:

- Generate a summary overview of a NewsML document (MandatoryData).

- NewsML node deletion.

- Searching for NewsML nodes by name, text content, and language.

- Filtering lists of NewsML nodes by name, text content, and language.

- Querying the element and attribute types allowed in a NewsML document.

To start the program, you must first ensure that the NewsML Toolkit
version 1.1, the ALT, and all required external packages are installed
and accessible in your Java classpath.  You may then simply type

  java -jar alt-demo.jar

to start the program, or, if you prefer, add alt-demo.jar to your
classpath and type

  java ALTDemo

In both cases, you may include the URLs of NewsML documents to open
when the program starts.

This program does not allow full editing of NewsML documents, but it
does allow you to prune unwanted nodes and save the results back to an
XML file.  Currently, the program makes no effort to stop you from
doing something stupid, like removing a node required by the NewsML
specification.


Enjoy!
