// REVISION HISTORY:
//
// 26 Jan 2001 YmL:
//		. initial revision
//
// 2002-06-19 YmL:
//		. added	logging	debug and error	messages to a file.
//
// 2004-02-06 YmL:
//	.	added a newline to generated messages.
//
// 2005-01-09 YmL:
//	.	now checks global $fvDEBUG[ "logfile" ] setting for 
//		logfile to output to. 
//	.	dumping to file has not been combined into a dumpmsg 
//		method.
//
// 2005-02-25 YmL:
//	.	added _error() support for cmdLine programs.
//
// 2005-03-20 YmL:
//	.	changed license for this file to HTMLArea from RPL.
//	.	quick hack to repurpose for Xinha.
