/**
 * Unpack the content read from <i>source</i> into <i>targetFolder</i>. If the

 * single folder and unpack the content of that folder, not including the folder
 * itself.//from   www .  j  a  v  a  2s .  c  o  m
 * 
 * @param source
 *            The input source. Must be in <i>TAR</i> format.
 * @param targetFolder
 *            The destination folder for the unpack. Not used when a <tt>fileCatcher</tt> is provided
 * @param skipTopFolder
 *            Set to <code>true</code> to unpack beneath the top folder
 *            of the archive. The archive must consist of one single folder and nothing else
 *            in order for this to work.
 * @param fileCatcher
 *            Used when specific files should be picked from the archive without writing them to disk. Can be
 *            <tt>null</tt>.
 * @throws IOException
