title: Erlang: How to include libraries
body: <p>I'm writing a simple Erlang program that requests an URL and parses the response as JSON.</p>
  
  <p>To do that, I need to use a Library called Jiffy. I downloaded and compiled it, and now i have a .beam file along with a .app file. My question is: How do I use it? How do I include this library in my program?. I cannot understand why I can't find an answer on the web for something that must be very crucial.</p>
  
  <p>Erlang has an include syntax, but receives a .hrl file.</p>
  
  <p>Thanks!</p>
