-        For any executed query, prints either the query, the parse
-        tree, the execution plan, or the query rewriter output to the
-        server log. <option>DEBUG_PRETTY_PRINT</option> selects are
-        nicer but longer output format.
+        These flags enable various debugging output to be sent to the
+       server log.  For each executed query, prints either the query text,
+       the resulting parse tree, the query rewriter output, or the execution
+       plan. <option>DEBUG_PRETTY_PRINT</option> indents these displays
+       to produce a more readable but much longer output format.
+       Setting <option>DEBUG_LEVEL</option> above zero implicitly turns
+       on some of these flags.
