Re: syntax diagramming tool

[Robert Lauriston <robert -at- lauriston -dot- com>]

In that Oracle doc it looks to me like both the text command syntax (
http://docs.oracle.com/cd/B19306_01/server.102/b14200/img_text/model_rules_clause.htm
) and the railroad diagram GIF (
http://docs.oracle.com/cd/B19306_01/server.102/b14200/img/model_rules_clause.gif
) are generated from EBNF (or whatever source Oracle uses to define
their SQL grammar).

Do you know any tools that can do that?
