+"""Utilities for the Nexmark suite.
+
+The Nexmark suite is a series of queries (streaming pipelines) performed
+on a simulation of auction events. This util includes a Command class used
+to terminate the streaming jobs launched in nexmark_launcher.py.
+
+Usage:
+To run a process for a certain duration, define in the code:
+ command = Command(process_to_terminate, args)
+ command.run(timeout=duration)
+
+To test, run in a shell:
+ $ python nexmark_util.py

> Currently we have a Java only implementation of Nexmark, a python based
> implementation would be nice to have to validate the direct and dataflow
> runners, but also to validate the new support of multiple SDKs in multiple
> runners via the runner/fn API.
