 As described in
 https://lists.buildbot.net/pipermail/devel/2015-August/011904.html

 http://docs.buildbot.net/0.8.12/manual/cfg-
 statustargets.html#configuration claims this works:
 {{{
     from buildbot.plugins import status
     c['status'].append(status.WebStatus(8080))
 }}}

 But it fails with

 {{{
     exceptions.AttributeError: Plugin buildbot.status:WebStatus does not
     implement IStatusReceiver: An object has failed to implement
     interface <InterfaceClass buildbot...IStatusReceiver>
 }}}

 The workaround seems to be to ignore the docs and do

 {{{
     import buildbot.status.html
     c['status'].append(buildbot.status.html.WebStatus(http_port=8080))
 }}}

 Shouldn't either the doc or the code should be fixed so the documented
 sequence works?

Comment:

 I suspect that just adding an `implements(..)` would be sufficient.
