<p style="margin-top:0;margin-bottom:0">I'm using rebar3 for release. I have mentioned
<span style="font-family: Consolas, Courier, monospace;">ssl</span> application in config file prior to
<span style="font-family: Consolas, Courier, monospace;">inets</span> application(though sequence doesn't matter) and as per my understanding rebar3 will take care of start sequence and I don't think so there is an option to define application start sequence
explicitly. Am I right ? </p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Let me know if there is any way to make sure to start
<span style="font-family: Consolas, Courier, monospace;">ssl</span> application before
