What is a Kotlin module?
<p>In the Kotlin documentation they are mentioning some kind of <em>module</em> for instance in the <a href="https://kotlinlang.org/docs/reference/visibility-modifiers.html">documentation</a> for the <code>internal</code> modifier.</p>

<p>However I couldn't find any definition of the term <em>module</em> itself. So what is meant by <em>module</em>?</p>
