17  * Simple implementation if the registry support functionality.
18  * The logging output is done onto System.out (for both specific and generic logs)
19  * in the following format:
20  *
21  * [Error|Warning|Log]: Main error message
22  * [Error|Warning|Log]: Child error message 1
23  * ...
24  * [Error|Warning|Log]: Child error message N
25  *
26  * The translation routine assumes that keys are prefixed with '%'. If no resource
27  * bundle is present, the key itself (without leading '%') is returned. There is
28  * no decoding for the leading '%%'.
