<para>
With DocBook, your world gets clearer. I will describe files such as <filename>docbook-example02.sgml</filename>. 
The following procedure illustrates how to make one:
</para>
    <procedure>
      <step>
	<para>Start a text editor such as <application>emacs</application>.</para>
      </step>
      <step>
	<para>Type the contents of your file. When you are done, save the file
	  using the key sequence <keycombo><keycap>Ctrl-x</keycap><keycap>Ctrl-s</keycap></keycombo> or 
	  the menu command <menuchoice><guimenu>File</guimenu>
	    <guimenuitem>Save Buffer</guimenuitem></menuchoice>.
	</para>
	<para>If you did not supply a file name earlier,
	  <application>emacs</application> will prompt you with the
	  <computeroutput>File to save in:</computeroutput>
	  message. Type a file name such as
	  <userinput>docbook-example02.sgml</userinput>, then press
	  <keycap>Enter</keycap> to save the file.</para>
      </step>
      <step>
	<para>
	  To check that you have actually made a file, use the <command>ls</command> command:
	</para>
	<screen><computeroutput>me@machine:~/docbook$</computeroutput> <userinput>ls -l</userinput>
-rw-r--r--    1 me       me           1702 May 23 14:54 docbook-example02.sgml
</screen>
     </step>
    </procedure>
    <para>When you have checked that you have a file, you can go on to <xref linkend="nextstep">.</para>
</chapter>
  <chapter id=nextstep>
    <title>The next step</title>
    <para>Here is what you want to do next …</para>
  </chapter>
