 <p>We are going to assume that your first project is a small standalone program using one of the common libraries for Common Lisp. Since Common Lisp is a general purpose high-level programming language, it can handle any common high-level language task.</p>
 <p>Common libraries are installed using <a href="http://www.quicklisp.org/">Quicklisp</a>!</p>
 <p>Go over there and install it, then come back to this tutorial.</p>
-<p>Let&#8217;s assume for the purpose of the starting project that you want to recursively walk a web server and take some action based upon the internal contents. We&#8217;ve supplied a minimal (not very robust or general) solution in <code>web-trotter.lisp</code>, available from <a href="src/web-trotter.lisp">our site</a>.</p>

 <p>Without examining the details of the Trotter, notice that there&#8217;s a line:</p>
 <p><code>(ql:quickload '(:drakma :split-sequence :cl-ppcre :babel))</code></p>
 <p>This tells Quicklisp to ensure that the libraries DRAKMA, SPLIT-SEQUENCE, CL-PPCRE, and BABEL are loaded.</p>
