[Buildbot-devel] Adding a log in a RemoteCommand

[Ben Hearsum]

Thanks Axel, I think you've just solved my problem. I (dumbly) and  
sendStatus()'ing 'stdio', which my brain keeps parsing as 'stdout'. As  
far as I can tell, LoggedRemoteCommand will already handle a 'stdout'  
-- so I'll give that a try tomorrow.

Cheers.
