"""
Glue execution module to link to the :mod:`fx2 proxymodule <salt.proxy.fx2>`.

Depends: :mod:`iDRAC Remote execution module (salt.modules.dracr) <salt.modules.dracr>`

For documentation on commands that you can direct to a Dell chassis via proxy,
look in the documentation for :mod:`salt.modules.dracr <salt.modules.dracr>`.

This execution module calls through to a function in the fx2 proxy module
called ``chconfig``.  That function looks up the function passed in the ``cmd``
parameter in :mod:`salt.modules.dracr <salt.modules.dracr>` and calls it.
