    <title>Set up translations</title>
  </links> 

  <p>You will need to set up your project and build system to work with
  translations.</p>

  <p>Create a <file>po/</file> subdirectory in your project directory and list
  the files which have translatable strings in <file>po/POTFILES.in</file>.
  List files <em>without</em> translatable strings in
  <file>po/POTFILES.skip</file>.</p>

  <p>Add the following lines to your <file>configure.ac</file>:</p>
  <code>
IT_PROG_INTLTOOL([0.50.0])
AC_SUBST([GETTEXT_PACKAGE], [$PACKAGE_TARNAME])
AC_DEFINE_UNQUOTED([GETTEXT_PACKAGE], ["$GETTEXT_PACKAGE"], [Package name for gettext])</code>

  <p>Add the following lines to your <file>Makefile.am</file>:</p>
  <code>
SUBDIRS = po
</code>
  <code>
AM_CPPFLAGS = -DPACKAGE_LOCALEDIR=\""$(datadir)/locale"\"
</code>
  <code>
@INTLTOOL_DESKTOP_RULE@
desktopdir = $(datadir)/applications
desktop_in_files = data/<input>applicationname</input>.desktop.in
desktop_DATA = $(desktop_in_files:.desktop.in=.desktop)
</code>

  <p>Run <cmd>intltoolize</cmd> to copy the intltool build infrastructure to
  the build tree before running <cmd>autoreconf</cmd>.</p>

  <p>Now that your build system and your source strings are ready for
  translation, you need to tell <app>gettext</app> three things:</p>

  <list>
    <item><p>the <em>translation domain</em>, generally the same as the
    application name</p></item>
    <item><p>the location where the built translations are installed</p></item>
    <item><p>the character encoding of the translations, generally
    UTF-8</p></item>
  </list>

  <example>
  <note>
    <p>This example assumes that your application is written in C. It will be
    slightly different for other programming languages.</p>
  </note>

  <p>Add the following line to the source file which contains your
  <code>main()</code> function:</p>

  <code>#include "config.h"</code>

  <p>Then, add the following lines to your <code>main()</code> function:</p>

  <code>
bindtextdomain (GETTEXT_PACKAGE, PACKAGE_LOCALEDIR);
bind_textdomain_codeset (PACKAGE_TARNAME, "UTF-8");
textdomain (GETTEXT_PACKAGE);
</code>
  </example>

  <p>Run <cmd>make <input>projectname</input>.pot</cmd> in the <file>po</file>
  directory. This runs <cmd>intltool-extract</cmd> to extract the translatable
  strings and put them in a po template (POT) file.</p>
