I see Executor(['docker-compose']) works for me

[kurtbrose]

>>> seashore.Executor(s, commands=['docker-compose']).docker_compose
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/kurtrose/sky/build/src/seashore/src/seashore/executor.py", line 187, in __getattr__
    raise AttributeError(name)
AttributeError: docker_compose

I think __getattr__ needs to take into account - / _ transformations?

[kurtbrose]

>>> seashore.Executor(seashore.Shell(), commands=['docker_compose']).docker_compose().interactive()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/kurtrose/sky/build/src/seashore/src/seashore/executor.py", line 150, in __call__
    return self._executor.prepare(self._name, *args, **kwargs)
TypeError: prepare() takes at least 3 arguments (2 given)

okay, I see how to do it:

>>> e = seashore.Executor(seashore.Shell(), commands=['docker_compose']).docker_compose
>>> e.docker_compose.version().interactive()
docker-compose version 1.11.2, build dfed245
docker-py version: 2.1.0
CPython version: 2.7.12
OpenSSL version: OpenSSL 1.0.2j  26 Sep 2016

I guess the only issue is docs
