None of the tarballs or zip files mentioned in this article have the .jar files or the lib sub-directory. Neither the SourceForge tarball nor the Coulom repository on github have the .jar files. We need a website where we can download the .jar files. Or we need a make file in the tarball which we can use to compile the Java source code into a .jar file on Linux. Isn't there another website, where we can find the .jar files?
The editor for the gogui article should remove the disinformation contained in the gogui article. The .jar file gogui.jar no longer exists in SourceForge. None of the other .jar files exist, either. The .tar.gz source file in SourceForge does not contain a lib subdirectory, where, supposedly, the .jar files are located.
