GNU Java programs under the gnu top-level package

Each of these programs is a package under the gnu top-level package. Some of them are copyright by the Free Software Foundation, and some by their authors. All of them are free software, and unless otherwise noted, the distribution terms are the GNU General Public License (20k characters) (GNU GPL).

If you would like to contribute additional Java programs to the GNU project, please contact <gnu-java@gnu.org>.

Using gnu as the top-level package goes against Sun's recommendation, which some people think is a bad idea, but we have reasons for the decision.
