NOTES eamoon@meadgroup.com 11june99
|
||||
- this node has some holes in it, but it's pretty useful starting
|
||||
point for writing producers.
|
||||
- I've tried to clean up the format negotiation a bit, which didn't
|
||||
fare too well when faced with an apathetic downstream node
|
||||
(LoggingConsumer.)
