What is -pa and -pz in erlang?
<p>I was trying to modify <code>mod_log_chat</code> module in <code>ejabberd-contrib</code> where I saw the following command in <code>build.sh</code></p>

<pre class="lang-bash prettyprint-override"><code>erl -pa ../ejabberd-dev/ebin -pz ebin -make
</code></pre>

<p>Can someone explain what is <code>-pa</code> and <code>-pz</code>? I am not getting a satisfactory information from web.</p>
