"""Script to call executables in `tox` envs.

The script takes two mandatory arguments:
1. the executable to call like e.g. `pylint`
2. a string with comma separated `tox` envs to check for the executable

All other arguments after are passed to the tool on call.

The script considers OS and calls the tool accordingly.
