cannot redirect the output to a file. See more at
https://bitbucket.org/hpk42/tox/issues/73/pipe-output-of-command-into-file
Bug fixes
~~~~~~~~~
- Fixes problem when the setup.py command try to import the package
its about to install in order to get the information like the
version. E.g. Django does that.
- Fixes problem when the setup.py command plays with `__file__` to
read, exec, or whatever.
