What is pip install -q -e . for in this Travis-CI build tutorial?
<p>I'm following <a href="http://cramer.io/2012/05/03/using-travis-ci/" rel="noreferrer">this tutorial</a> for testing a Django project with Travis-CI. In this example script:</p>

<pre><code>env:
  - DJANGO=1.2.7
  - DJANGO=1.3.1
  - DJANGO=1.4
install:
  - pip install -q Django==$DJANGO --use-mirrors
  - pip install -q -e . --use-mirrors
</code></pre>

<p>What exactly does <code>pip install -q -e .</code> perform? There is no -q flag and I'm not sure what the meaning of this is for <code>-e</code> is in the <a href="https://pip.pypa.io/en/stable/reference/pip_install/#cmdoption-e" rel="noreferrer">pip documentation</a>:</p>

<blockquote>
  <p>[-e flag]: Install a project in editable mode (i.e. setuptools "develop mode") from a local project path or a VCS url.</p>
