// Author: Doug Card
-// Modified by:
-// Mods: Dec, 1998: Added support for SQL statement logging and database
-// cataloging
+// Modified by: George Tasker
+// Bart Jourquin
+// Mark Johnson, wxWindows@mj10777.de
+// Mods: Dec, 1998:
+// -Added support for SQL statement logging and database cataloging
+// April, 1999
+// -Added QUERY_ONLY mode support to reduce default number of cursors
+// -Added additional SQL logging code
+// -Added DEBUG-ONLY tracking of Ctable objects to detect orphaned DB connections
+// -Set ODBC option to only read committed writes to the DB so all
+// databases operate the same in that respect
