Period at end of comment .  Also why to stdout rather than a well defined file
or use redirect_stdout?

[davidjames, 2010/09/25 22:43:46]

What's redirect_stdout? Is there a difference between using redirect_stdout and
just outputting to stdout?

If we directed output to a file, would said file be accessible from the buildbot
web UI? If so, great, that's exactly what we want.

My understanding is that it isn't easy to make new files accessible from the
buildbot web UI. So outputting to stdout along with build output is next best
thing.

But if it's not terribly hard to write output to a file and make that file
accessible from the web UI, I'd love to do that.
