CHANGELOG and documentation

[Tom Tromey]

Anthony> I created a NEWS file a long time ago, but we don't maintain
Anthony> it.  We probably should.

I think we definitely should.  I think we should also add news entries
to the news section of the front page.

Matt> * Reflection (java.lang.reflect.*). [Can someone elaborate?]

Anthony> Reflection works, including invocation, under both x86 and
Anthony> PPC Linux.  Feedback from others is encouraged.

Yes, reflection ought to work anywhere there is a libffi port.  We
just haven't tested it anywhere else.
