Thanks for the heads up Sairhei! I ended up backporting 9f= ront's ^ and _ to my copy of plan9port. It's not as flexible as hav= ing the named pipe around but it answers the immediate question.

I love Sam, though it is because I know it so well.

btw, anyone written scripts to allow the plan9 wiki to be edited from Sam? = maybe the wiki is outmoded these days?
