title: Makefile on terminal
body: <p>I have seen a "basic Makefile tutorial" today, but I still don't understand a few things:</p>
  
  <ol>
  <li>What does the '&amp;' character do in the line: "emacs Makefile &amp;" ?</li>
  <li>After I have opened the emacs editor and created the Makefile file, how do I use it in order to compile my "source_code.c" file??</li>
  </ol>
  
  <p>Thanks in advance,</p>
