 <p>The goal of this tutorial is only to help you realize the possibilities of the Alignment <abbr>API</abbr> and implementation. It can be played by invoking each command line from the command-line interpreter. In this example we use the <tt>tcsh</tt> syntax but the main specific syntax is the first one:</p>
 <div class="terminal">
-$ setenv CWD `pwd`
+$ setenv CWD `pwd` 
 </div>
