A release x.y consists of several files:

The binary package. It contains the jar file with the compiled classes you need when you want to "use" the associations package, i.e. use it in your own programs.
The source package. It contains the sources for all the classes in the binary package.
The tests package. It contains the automated tests I use to try to make and keep the package stable, both as source and compiled class files. Needs junit to be usable.
The documentation package. Currently only contains very incomplete API javadoc.
