OK, several people have asked the question, "What if everyone did
that?" But no one has answered the question. :-) I don't yet see the
problem if everyone did that. You'd have JARs with Main classes, the
manifest in each would point at the Main, and you could execute any of
the jar files with "java -jar foo.jar". Other JARs might have Main
classes in the default package, but they would be properly shadowed by
the Main in the JAR being executed. There'd be no conflict.

The standard convention of a README works fine. I see this as an easter
