pyinvoke 1.0.0

Pyinvoke is a very simple module that is intended to make invoking Python applications in modules less pain. Since Python’s -m option will load the module as __main__ module and not as the module it is intended to be loaded as, you can get interesting errors.

$ python -m module.main
Traceback (most recent call last):
  File "module/main.py", line 7, in <module>
    from .stuff import ham
SystemError: Parent module '' not loaded, cannot perform relative import

Well, shucks! Works as expected with pyinvoke!

$ pip3 install pyinvoke
$ python3 -m pyinvoke module:main
