Log4s Error Handling
Log4s uses a class called EsLogLog to report internal error and debug information. EsLogLog writes to Transcript TTY.  What it writes, and whether it writes at all, are controlled by two ini file variables:
debugEnabled - EsLogLog will write debug messages if this value is true; otherwise it will write only errors.
quietMode - EsLogLog will write neither error or debug messages if this value is true.  It will be completely silent.
