"""
IsOpenStackCompute
==================

The ``IsOpenStackCompute`` component uses ``PsAuxcww`` parser to determine
OpenStack Compute node. It checks if 'nova-compute' process exist, if not raises
``SkipComponent`` so that the dependent component will not fire. Can be added as
a dependency of a parser so that the parser only fires if the
``IsIsOpenStackCompute`` dependency is met.
