title: What does the : character mean in LD_LIBRARY_PATH?
body: <p>I don't understand what this script is doing. What is the <code>:</code> sign within LD_LIBRARY_PATH doing?</p>
  
  <pre><code>#!/bin/ksh
  LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH ${B%/bin/*}/lib/exec/${0##*/} "$@"
  </code></pre>
  
  <p>Thanks</p>
