    This command helps making revent recordings. It will automatically
    deploy revent and even has the option of automatically opening apps.

    Revent allows you to record raw inputs such as screen swipes or button presses.
    This can be useful for recording inputs for workloads such as games that don't
    have XML UI layouts that can be used with UIAutomator. As a drawback from this,
    revent recordings are specific to the device type they were recorded on.

    WA uses two parts to the names of revent recordings in the format,
    {device_name}.{suffix}.revent.

     - device_name can either be specified manually with the ``-d`` argument or
       it can be automatically determined. On Android device it will be obtained
       from ``build.prop``, on Linux devices it is obtained from ``/proc/device-tree/model``.
     - suffix is used by WA to determine which part of the app execution the
       recording is for, currently these are either ``setup`` or ``run``. This
       should be specified with the ``-s`` argument.
