Re: Process diagrams with dot and some glue using Org-mode

[Karl Voit <devnull@Karl-Voit.at>]

Sorry, minor mistake: I could not find out why dot is not able to
mix directed and not directed graphs in one diagram. Therefore I had
to replace th "-" in the node table with ">" and the corresponding
results as well:

This results in a diagram as shown in: http://qr.cx/wEFr
