/**
*CVS Log info
*$Log$
*Revision 1.4  2005/07/09 23:15:04  ddiego
*merging in changes from devmain-0-6-7 branch.
*
*Revision 1.3.2.3  2005/05/06 21:13:44  marcelloptr
*extended message in dumpDebugInfo
*
*Revision 1.3.2.1  2005/03/15 01:51:51  ddiego
*added support for Format class to take the place of the
*previously used var arg funtions in string utils and system. Also replaced
*existing code in the framework that made use of the old style var arg
*functions.
*
*Revision 1.3  2004/12/01 04:31:41  ddiego
*merged over devmain-0-6-6 code. Marcello did a kick ass job
*of fixing a nasty bug (1074768VCF application slows down modal dialogs.)
*that he found. Many, many thanks for this Marcello.
*
*Revision 1.2.2.2  2004/11/09 02:01:39  ddiego
*made a change to the way the toString() method is implementing formatting the info
*
*Revision 1.2.2.1  2004/10/21 18:19:19  augusto_roman
*Fixed Object's toString() method - it used c_str() instead of ansi_c_str() in sprintf() - aroman
*
*Revision 1.2  2004/08/07 02:49:14  ddiego

*This checks in a bunch of changes to the FoundationKit for OSX
*porting. The thread, mutex, semaphor, condition, and file peers
*have all been implemented and tested. The file peer could be improved
*and needs search functionality. The locale peer is only partially
*complete, but the functions will return values. The unicode transition
*is also finished and works OK now.
