Invoke __init__.py package with direct call to the module contained in the package
<p>What the cleanest way to invoke <code>__init__.py</code> package with direct call to the module contained in the package?</p>

<pre><code>package
    __init__.py
    mod.py
</code></pre>

<p><code>__init__.py</code>:</p>

<pre><code>from some_installed_package import very_important_callable


very_important_callable()
</code></pre>

<p>mod.py:</p>

<pre><code>#!/usr/bin/env python
def some_code():
    return 'some object'
</code></pre>

<p>In this step I need to invoke <code>__init__.py</code>:</p>

<pre><code>./mod.py
</code></pre>
