28 /**
29  * The purpose of this class is to create localized ConfigException
30  * objects conveniently. The code is here instead of in ConfigException itself
31  * to avoid passing in a StringManager reference everytime a ConfigException
32  * is thrown -- and the concommitant increase in the number of constructors.
33  * To use this class you create one instance for each calling class so that
34  * the correct properties file is chosen automatically.
35  *
36  * Note that StringManager only uses the *package* name to locate the properties file.
37  * Also note that only this package can access this class. Thus the StringManager
38  * can be shared by all callers of this class.
