title: -bash: scala: command not found
body: <p>I'm trying to install scala on my mac (Maverick).
  I downloaded and unarchived it.
  I then put myself from where it was unarchived and inside the /bin folder in the terminal.
  But when I run "scala" or "scalac" I get :</p>
  
  <p><code>-bash: scala: command not found</code></p>
  
  <p>Why?</p>
