-------------------------------------------
Thanks, Rick. The latest patch looks good to me (perhaps except some lines
exceeding 80 chars), so +1 from me.

> It would be nice to be able to tell the compiler to use user-written
> formatters for pretty-printing Derby's abstract syntax trees. For instance,

> DERBY-791, including the Eclipse-based tree grapher written by Kay Röpke.
