 *	SYNOPSIS START

	This sample program demonstrates the cross-platform ODBC database classes
	donated by the development team at Remstar International.

	The table this sample is based on is developer contact table, and shows
	some of the simple uses of the database classes wxDB and wxTable.

 * 
 *		For each database object created which uses this wxDB pointer
 *    connection to the database, when a CommitTrans() or RollBackTrans()
 *    will commit or rollback EVERY object which uses this wxDB pointer.
 *
 *    To allow each table object (those derived from wxTable) to be 
 *    individually committed or rolled back, you MUST use a different
 *    instance of wxDB in the constructor of the table.  Doing so creates 
 *		more overhead, and will use more database connections (some DBs have
 *    connection limits...), so use connections sparringly.
 *
 *		It is recommended that one "main" database connection be created for
 *		the entire program to use for READ-ONLY database accesses, but for each
 *		table object which will do a CommitTrans() or RollbackTrans() that a
 *		new wxDB object be created and used for it.
