title: Where is SCALA_HOME on Ubuntu?
body: <p>I installed Scala on Ubuntu using the following</p>
  
  <pre><code>sudo apt-get install scala 
  
  ~$ which scala
  /usr/bin/scala
  
  ~$ whereis scala
  scala: /usr/bin/scala /usr/bin/X11/scala /usr/share/man/man1/scala.1.gz
  
  ~$ scala -version
  Scala code runner version 2.9.1 -- Copyright 2002-2011, LAMP/EPFL
  </code></pre>
  
  <p>My question is what should I put in the variable SCALA_HOME? /usr/bin ? </p>
