One thing puzzles me though: The devtests are in the v2-branch. So I
would have guessed that they are intended to be used in this form only
for v2-development.
Having looked quickly at the current tests concerning valves they seem
not to be version-dependent. And there is even a
v3HttpListenerDynamicConfig-folder. So propably they _are_ also intended
for v3. But how do I specify which server to use. Are there any
command-line flags? And can I specify which tests to run. This would be
necessary since v3 does not yet support everything v2 supported.
