//// History /////////////////////////////////////////////////////////////////
// //
// 10.02.2001 mcn - Created //
// 10.16.2001 mcn - Added static versions of AddLine() so you don't need //
// to explicitly create a log //
// 10.17.2001 mcn - Added support for carriage returns in printed lines //
// 10.24.2002 eap - Added kDebugOutput flag for writing to debug window //
// 10.25.2002 eap - Updated to work under unix //
// 12.13.2002 eap - Added kStdout flag //
