What is the purpose of the c flag in the "conda install" command : <p>I'm learning to setup python environments using conda, and I noticed that on the anaconda cloud website they recommend  installing packages using the sintax </p>

<pre><code>conda install -c package
</code></pre>

<p>However on the conda documentation they use the same command without the c flag.</p>

<p>Could anyone explain to me what is the purpose of the c flag and when should it be used?</p>
