Babel 6 error "Using removed Babel 5 option"
<p>I'm requested to write a new app using some modules from the old one. We'd like also to test a transition to Babel 6 for the old app.</p>

<p>I have two .babelrc, one wrote for Babel 5 in an upper directory and the other for Babel 6 in a sub directory:</p>

<pre><code>├── .babelrc       # babel5 config
├── app
│   └── foo.js     # should work with both babel5 and babel6
└── new_app 
    ├── .babelrc   # babel6 config
    └── bar.js     # import ../app/foo.js
</code></pre>

<p>When I run Babel 6 from the sub directory, it throws an error:</p>

<pre><code>Using removed Babel 5 option etc
</code></pre>

<p>So I tried to add <code>breakConfig: true</code> and it throws another error:</p>

<pre><code>This is not a necessary option in Babel 6
</code></pre>

<p>Is there a way with Babel 6 to skip parsing upper configs as it was with Babel 5 using the <code>breakConfig</code> option?</p>
