Note: Delegator is a replacement for Envoy.
This is a convenience wrapper around the subprocess module.
You don't need this.
But you want it.
Run a command, get the response:
>>> r = envoy.run('git config', data='data to pipe in', timeout=2)
>>> r.status_code
129
>>> r.std_out
'usage: git config [options]'
>>> r.std_err
''Pipe stuff around too:
>>> r = envoy.run('uptime | pbcopy')
>>> r.command
'pbcopy'
>>> r.status_code
0
>>> r.history
[<Response 'uptime'>]
