How are the ascii diagrams in RFC's generated?

Question

Not sure if this is the correct stackexchange to ask this question, but I was wondering whether anyone knows if the ascii diagrams in http://tools.ietf.org/rfc/rfc5755.txt page 6 are handcrafted or generated using a program that takes the nodes and transitions as input.

If they are generated, does anyone know which program?

Directly searches on Google do not turn up anything relevant.

They are many ASCII diagram converters online. You can draw quickly in any drawing tool for example, MsPaint an then can be converted to ASCII art. — Sunil Bojanapally, Dec 06 '12 at 10:03
don't know how they do it in the RFCs but try this: http://www.asciiflow.com/ Lets you draw with ASCII art, no conversion needed... — eckes, Nov 15 '13 at 10:37

I believe that Emacs picture-mode, table-mode (M-x table-insert or M-x table-recognize) and possibly another modes simplify ASCII editing.

Also read about proposal to use PDF formats for RFC:

If you prefer, you could also draw ASCII diagrams manually with asciiflow. I find this tool pretty handy from time to time. http://asciiflow.com/
