+Query logging may be turned on by adding a -D QUERY_LOG=ON. This will create a\r
+file called query.log in the working directory. Straight SQL statements will\r
+be captured, as well as the setup of prepared statements. Each step through a\r
+prepared statement is also logged, but the details are not, so there should be\r
+no sensitive information in this log file.\r
