==== subprocess ====

[[https://github.com/google/python-subprocess32|python-subprocess32]]: Backport of Python 3.2 `subprocess` module to 2.7. Use:

{{{#!highlight python numbers=off
if os.name == 'posix' and sys.version_info[0] < 3:
    import subprocess32 as subprocess
else:
    import subprocess
}}}

Can serve as a complete replacement for Python 2.7's `subprocess` module.
