Please list here any libraries and external programs in which your program depends (or will depend) and which are not normally found in a minimum Free Operating system.

If you project includes Java classes, please make sure that they can be run in one of the available Free Java environments (see http://www.gnu.org/software/java/). And explain that in this registration form. One common source of trouble is the use of Swing, since there are currently no free implementations of it (JDK is not Free Software).
