Well, the dot file will probably be lurking in /tmp/usession-*/
somewhere.  I don't know if there's an "official" way of getting hold
of it, though.

One you have the dot file, "dot -Tps flow.dot > flow.ps && lp flow.ps"
or whatever should work fine.

I'm not sure what you're referring to.  The docs you linked to look
correct to me (i.e. there is no bin/translator.py any more in svn).


  we're already scrubbing the face of intuition with steel wool,
  setting it on fire, then putting it out with an axe <wink>.
