If I want to say that I support only version 6.1.0 and 6.3.0 of windows, how do I express that in the cookbook metadata?

```
supports 'windows', '~> 6.1.0', '~> 6.3.0' # will throw exception

```

From looking at the [code](https://github.com/chef/chef/blob/master/lib/chef/cookbook/metadata.rb#L729), specifying multiple version arguments will throw an ObsoleteDependencySyntax exception, and calling supports on the same platform will simply [overwrite the last version arg](https://github.com/chef/chef/blob/master/lib/chef/cookbook/metadata.rb#L284) from what I can tell.

```
supports 'windows', '~> 6.1.0'
supports 'windows', '~> 6.3.0' # overwrites the previous

```

Is there actually a way to do this?

Perhaps obtusely helpful, but I would just pick the higher of the two and  
state that version explicitly, i.e.

supports ‘windows’, ‘6.3.0’

But he’d like to support 6.1.0 as well, but not 6.2.0.
