  <H1>A Quick and Dirty Recursive Descent Parser Generator</H1>

  <P>Here is a recursive descent parser generator, written in
    <a href="http://www.cliki.net/">Common Lisp</a>.</p>

  <P>It generates the scanner and parser in lisp, or in a pseudo-basic.
    It is possible to add generation of the parser in other programming

  <p><b>Note:</b> those are old files, an ancient version of RDP.
    For real uses, get the current sources from gitorious; the RDP
    Generator is now included in the com.informatimago repository:</p>
  <pre class="commands">
    git clone https://git.gitorious.org/com-informatimago/com-informatimago.git

  <p>or you can just get it with <a href="http://quicklisp.org/">quicklisp</a>:</p>
  <pre class="commands">
    (ql:quicklisp :com.informatimago.rdp)
