def deduce_command():
'''Deduce which command to use for ``powerline``
Candidates:
* ``powerline``. Present only when installed system-wide.
* ``{powerline_root}/scripts/powerline``. Present after ``pip install -e``
was run and C client was compiled (in this case ``pip`` does not install
binary file).
* ``{powerline_root}/client/powerline.sh``. Useful when ``sh``, ``sed`` and
``socat`` are present, but ``pip`` or ``setup.py`` was not run.
* ``{powerline_root}/client/powerline.py``. Like above, but when one of
``sh``, ``sed`` and ``socat`` was not present.
* ``powerline-render``. Should not really ever be used.
* ``{powerline_root}/scripts/powerline-render``. Same.
