0003 // ELseverityLevel.cc - implement objects that encode a message's urgency
0004 //
0005 //      Both frameworker and user will often pass one of the
0006 //      instantiated severity levels to logger methods.
0007 //
0008 //      The only other methods of ELseverityLevel a frameworker
0009 //      might use is to check the relative level of two severities
0010 //      using operator<() or the like.
