adds files this adds mkfile and plumbto.c source code. The project works already, you need the channel in your plumb rules echo plumb to chanselect >> /mnt/plumb/rules the messages need destination to this channel, as well as the attribute: channels=chan1,chan2,chan3 Whenever a message arrives there, the window pops up and you can click the correct destination channel (these are buttons). The message is altered (the channels attribute is removed) and delivered.
