This version of weka.jar is a developer snapshot version which allows weka.jar
to be run with the latest Java/OpenJDK versions, e.g., Java/OpenJDK 25 LTS.  It
got created to allow out-of-the-box usage of Weka for business adminstration
students who may not have the knowledge yet to setup the environment to allow
one to immediately take advantage of Weka.

The developer snapshot version (3.9.7) in this package was created and made
available by Prof.  Eibe Frank: kudos and *many* thanks!

---

Usage: open a command line window/terminal and issue "setupWeka" on Windows
       and "source sh ./setupWeka.sh"

Test: run "java -jar weka.jar" and the Weka GUI should be brought up.

The directory "WU\02_PavicJacov\nutshells_examples" includes all nutshell
examples in Java that the student created in his seminar paper.  In addition the
subdirectories include the equivalent ooRexx versions.  Hence you can test the
environment by changing into the directory
"WU\02_PavicJacov\nutshells_examples\data_visualization" and then run, e.g.,
"java data_visualization" and then "rexxj data_visualization" (on Unix use
"rexxj.sh" instead).

The samples in "WU/01_TestWeka" only work, if the "wekaDeeplearning4j" package
got successfully installed (cf. the readme.txt file in that directory).

To test ooRexx and its Java bridge BSF4ooRexx85 run "rexxjh rxTestWeka.rxj"
(use "rexxjh.sh rxTestWeka.rxj" on Unix), which will result in the same output
as the Java program.

The subdirectory WU/02_PavicJacov contains an introduction to Weka in form of a
seminar paper with a zip archive of Java nutshell examples. These examples were
used to create the equivalent ooRexx programs. In addition there is an ooRexx
program that demonstrates how to test multiple classifiers and learn about its
options.
