Allow tox to ignore missing python interpretors - pass when some are missing
Tox should be able to run tests on all available (defined) interpretors but it should not fail if one or more of them are missing.
This is a feature request that would allow users to execute tox on various systems using the same tox.ini command.
It would be essential for tox to return a success return code when this option is used.
One of the main reasons for asking this, is usage of tox in automation, where you want to run tox on different platforms with the same configuration for all of them.
