plumbto - select plumb destination channel
Plumbto listens on the chanselect plumb channel for messages
containing the channels attribute. It then presents a but-
ton for each destination channel in the comma-separated list
provided as a value for the channels attribute.
After selection, the channels attribute is removed and the
message is forwarded to the selected port.
Plumbto hides itself on startup. It unhides automatically
when receiving a message.
