Command line
============

You can use these APIs directly from the command-line using the `vaurienctl`
cli tool.

With it, you can either list the available handlers, get the current one or set
the handler to another one. Here is a quick demo::

    $ vaurienctl list-handlers
    delay, error, hang, blackout, dummy
    $ vaurienctl set-handler blackout
    Handler changed to "blackout"
    $ vaurienctl get-handler
    blackout
