      <para>The idea of this reference card is to provide new users of
      Debian GNU/Linux with the most important commands.  Basic (or
      better) knowledge of computers, files, directories and the
      command line is required.  Some acronyms related to Debian
      GNU/Linux can be found <link linkend="acronyms">here</link>.</para>

    <title>Print, Fold, and Enjoy</title>

    <warning>
      <simpara>The reference card has been designed for printers
      that are able to print whole pages, without large margins!  On
      my own private printer (HP Inkjet) or other so-called consumer
      printers you cannot print the card!</simpara>
    </warning>

      </mediaobject>
    </informalfigure>

    <para>First, the paper side with the title and the legal notice
    (copyleft) are on the back.  Fold the right third of the paper to
    the small mark at the upper margin between the left and middle
    third.  Now fold the left third over the right one.  The title
    page should be in the front, the legal notice on the back.  If
    not, try again.</para>

    <para>Of course, you may alter the reference card to your needs and
    create a customised refcard.  You need to install the build
    dependencies with <command>apt-get build-dep refcard</command>;
    these are mostly:
    <literal>docbook-xsl</literal>,
    <literal>texlive-extra-utils</literal>,
    <literal>pdftk</literal>,
    <literal>po4a</literal>,
    <literal>dblatex</literal>,
    <literal>poppler-utils</literal>, and
    <literal>xsltproc</literal>.</para>

    <!-- para>If you like to have a sponsors advertisement on the back
    (between the last entries and the copyleft notice), e.g. for the
    German version, just call: <command>make refcard-de-a4.pdf
    AD=ad-example.tex</command>.  The file could be sth. like:</para>

    <programlisting linenumbering="numbered" format="linespecific"
    id="ad-example"><xi:include
    xmlns:xi="http://www.w3.org/2003/XInclude" href="ad-example.tex"
    parse="text"/></programlisting -->

    <para>If you like to translate the reference card into your
    language, please contact me first, so that duplicated work is
    prevented.</para>

    <para>If you are going to translate the refcard, make sure to</para>

    <orderedlist>
      <listitem>
	<para>use the file <filename>po4a/entries.pot</filename> as

      </listitem>
      <listitem>
	<para>use <literal>UTF-8</literal> as encoding.</para>
      </listitem>
    </orderedlist>

    <para>Use whatever editor you like, but it must work with UTF-8.
    A nice editor for translations is <literal>poedit</literal>.
    If you happen to use Emacs (<literal>emacs24</literal>),
    try <literal>gettext-el</literal>.</para>

    <warning>
      <simpara>Because other languages might be more verbose than
      English (and German <emphasis>is</emphasis> more verbose), the
      translation might not fit on one sheet!  Translators need to
      re-phrase things!  The translation does not need to be 100%
      exact, it&apos;s more important, that everything fits on the
      card!</simpara>

      <simpara>The reference card has been designed for international
      paper format (ISO A4) - the US letter format has less space.
      This applies to English, French, and Spanish.</simpara>
