RFC 3977 explicit requires the CAPABILITIES command to work for
conformance. It should not be hard to implement it, so in my opinion
it should be listed as required.

@TOPIC: I will try to create a async_chat wrapper for the NNTP
protocol. I think that this should not be very hard. The only
difficulty would be the parsing of the command with multiple lines as
argument.
