that I like unit tests, my Unicode conversion work is going to have to
be thorougly tested for reasons I will outline in
http://thdltools.sf.net/BuildSystems.html later today.
Added the freely licensed JUnit 3.8.1 binary to the repository, along
with some README files. Added a new supporting buildfile,
junitbuild.xml. 'ant clean check' is now good to go (though it uses
the text UI for JUnit, and some developers may want the Swing GUI)
Also, I cleaned up build.xml a bit, including adding all buildfiles
(but not junit.jar and things like that) to the source distribution
('ant src-dist') rather than just build.xml.
