Lewis John McGibbney commented on NUTCH-1188:
---------------------------------------------

Thank you for this patch. In the short term, when we get one other +1, I wo=
uld like to commit. Can I ask you to have a look @ NUTCH-1138 and comment o=
n whether the patch is any use for your activities. It is our vision to rem=
ove LogUtil and use the Slf4j/Log4j framework for all logging.
Thank you very much for this patch.

});
