cl-markup library - Shammer's Philosophy

I found the library which helps writing html in lisp, that library is cl-markup. To use this library, execute the following commands.

(ql:quickload "cl-markup")
(defpackage html-sample (:use :cl :cl-markup))
(in-package :html-sample)

The above commands are preparing. Output html command likes below.

(html
  (:head
    (:meta :content "text/html" :charset "UTF-8")
    (:title "cl-markup sample"))
  (:body
    (:p "Hello, cl-markup!")))

This command result is below, except escape characters.

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
  <head>
    <meta content="text/html" charset="UTF-8">
    <title>cl-markup sample</title>
  </head>
  <body>
    <p>Hello, cl-markup!</p>
  </body>
</html>

I added (ql:quickload :cl-markup) to ccl-init.lisp.

In my next step, how can I write file these html, not standard output. I want to make clear how to use Quicklisp easy. I will tidy the Quicklisp initialization steps.
