-How to help:
-
-- **support more log formats**: by submitting `human.Handler` implementations.
-- **live querying**: add support for filtering in log output in real time.
-- **charting**: some key-values have semantics that could be charted in real time. For
-  instance, durations, frequency of numeric values, etc. See the [l2met][] project.
