At the 2007 International Rexx Symposium the logging framework for Open Object Rexx (ooRexx) got introduced, using the name "log4r". As it had turned out there had been a package existing already by the same name, created for the programming language "Ruby".

In order to not allow any confusion the ooRexx logging framework (modelled after Apache's log4j) had been renamed to "log4rexx" and got published by the author on 2007-05-21.
