26 * Generally, client need to pass own error information/exceptions from within implementations of the callback methods they supply.
27 * However, there's no straightforward way to alter throws clause for these methods, and alternatives like generic {@link Exception} or
28 * library's own {@link HgException} are rather obscure. Suggested approach is to wrap whatever exception user code produces with
29 * {@link RuntimeException} subclass, {@link Wrap}. Then, unwrap and re-throw with checked {@link HgCallbackTargetException}.
30 *
31 * FIXME REVISIT perhaps, shall just throw HgCallbackTargetException from any handler, and do not catch anything in commands at all?
