[rabbitmq-discuss] publisher confirmations

[Roey Berman]

Thanks for the quick reply.

At first I used the code from the example you referred me to but it doesn't
handle the "multiple" flag and NAcks from the server.

I know my code handles the "multiple" flag, but don't know about NAcks.
I don't really know how to test for nacks since I've never gotten them from
rabbitmq server.

Once I know my code handles all responses correctly I will create a pull
request for the pika example code.
