package org.eclipse.core.internal.registry;

import org.eclipse.core.runtime.IStatus;

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