### Tox.ini **Tox.ini**
To generate tox.ini, use the `toxgen.py` tool located in `tools/` and provide To generate tox.ini, use the `toxgen.py` script by first installing
that script as input the `tox-tmpl.ini` file to generate the final `tox.ini` [toxgen](https://pypi.python.org/pypi/toxgen/) and then provide that script
file. as input the `tox-tmpl.ini` file to generate the final `tox.ini` file.
For example: *For example:*
$ ./tools/toxgen.py -i tox-tmpl.ini -o tox.ini $ toxgen.py -i tox-tmpl.ini -o tox.ini
