Newsdeck practice publisher. Each address behaves one way, always:
/rss.xml /atom.xml /gn.xml     stand-in feeds used by the feature audit (dates kept recent)
/page.html                      a web page that points to /rss.xml (website discovery)
/feed                           a normal feed with 5 stories (add ?anything to make a separate copy)
/slow?ms=7000                   a normal feed, sent after the given wait (at most 25 seconds)
/status/500                     answers with that error code (any code from 400 to 599)
/notfeed                        a web page with no feed in it
/empty                          a valid feed with no stories
/huge                           a valid feed with 300 long stories (about 1.3 MB)
/toolarge                       9 MB of feed text (more than Newsdeck accepts)
/redirect?to=ADDRESS            sends the visitor on to ADDRESS (one redirect)
/loop/1                         redirects forever
/down-after/TIME                a normal feed until TIME (milliseconds since 1970), then error 500
/changing?every=60              one story whose headline and summary change every N seconds (same address)
/picture-until/TIME             one story with a picture until TIME, then the same story without it
