        "\n"
        "Columns with CHAR or VARCHAR as field type are ignored. DATETIME, DATE and TIME "

        "NULL are skipped if not suppressed by the --ignore-null option. Ideally, the query "
        "is compiled in a way that no NULL field is returned. With the --display option the "
        "result of the request is printed on the screen (NULL skipping still in action). "
        "This can be useful to create an ascii file or to show results as 'SHOW DATABASES' "
        "or 'EXPLAIN table'. To redirect the contents into an ascii file, the option -v0 "
        "is useful. To suppredd writing to an output file --null can be used.\n"

        "The default is to read the query from a file called rootify.sql. Except if a different "
