What is pipenv [dev-packages] section for? : <p>I'm learning <a href="https://pipenv.readthedocs.io/en/latest/" rel="noreferrer">pipenv</a> and there's something I don't quite understand.  Apparently your Pipfile can contain two sections:</p>

<pre><code>[packages]
...

[dev-packages]
....
</code></pre>

<p>As I understand it, the packages section is where the packages that you install are listed.  But what is the dev-packages section for?  How is it different from the packages section?</p>
