+    <file name="hello.c" printme="1">

+    </para>
+
+    <para>
+    First prepare the <filename>hello.c</filename> program for
+    internationalization. Change the previous code so it reads as follows:
+    <scons_example name="ex3">
+    <file name="hello.c" printme="1">
+    /* hello.c */
+    #include &lt;stdio.h&gt;

+    int main(int argc, char* argv[])
+    {

+      setlocale(LC_ALL, "");
+      textdomain("hello");
+      printf(gettext("Hello world\n"));
+      return 0;
+    }
+    </file>
+    </scons_example>
+    Detailed recipes for such conversion can
+    be found at <ulink
+    url="http://www.gnu.org/software/gettext/manual/gettext.html#Sources">
+    http://www.gnu.org/software/gettext/manual/gettext.html#Sources</ulink>.
+    The <function>gettext("...")</function> has two purposes.
+    First, it marks messages for the <command>xgettext(1)</command> program, which
+    we will use to extract from the sources the messages for localization.
+    Second, it calls the <literal>gettext</literal> library internals to
+    translate the message at runtime.
+    </para>
+
+    <para> 
+    Now we shall instruct SCons how to generate and maintain translation files.
+    For that, use the &b-link-Translate; builder and &b-link-MOFiles; builder.
+    The first one takes source files, extracts internationalized
+    messages from them, creates so-called <literal>POT</literal> file
+    (translation template), and then creates <literal>PO</literal> translation
+    files, one for each requested language. Later, during the development
+    lifecycle, the builder keeps all these files up-to date. The
+    &b-link-MOFiles; builder compiles the <literal>PO</literal> files to binary
+    form. Then install the <literal>MO</literal> files under directory
+    called <filename>locale</filename>.
+    </para>
+
+    <para>  The completed 
+    <filename>SConstruct</filename> is as follows:
+    <scons_example name="ex4">

+    Compile project with <command>scons</command>. This time, the

+    scons: done building targets.
+    </screen>
+    </para>
+    <para>
+    The next example demonstrates what happens if we change the source code
+    in such way that the internationalized messages do not change. The answer
+    is that none of translation files (<literal>POT</literal>,
+    <literal>PO</literal>) are touched (i.e. no content changes, no
+    creation/modification time changed and so on). Let's append another
+    line to the program (after the last printf), so its code becomes:
+    <scons_example name="ex6">
+    <file name="hello.c" printme="1">
+    /* hello.c */
+    #include &lt;stdio.h&gt;
+    #include &lt;libintl.h&gt;
+    #include &lt;locale.h&gt;
+    int main(int argc, char* argv[])
+    {
+      bindtextdomain("hello", "locale");
+      setlocale(LC_ALL, "");
+      textdomain("hello");
+      printf(gettext("Hello world\n"));
+      printf(gettext("and good bye\n"));
+      printf("----------------\n");
+      return a;
+    }
+    </file>
+    </scons_example>
+    Compile the project. You'll see on your screen
+    <screen>
+    user@host:$scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.
+    scons: Building targets ...
+    Entering '/home/ptomulik/projects/tmp'
+    xgettext --package-name=hello --package-version=1.0 -o - hello.c
+    Leaving '/home/ptomulik/projects/tmp'
+    Not writting 'messages.pot' (messages in file found to be up-to-date)
+    gcc -o hello.o -c hello.c
+    gcc -o hello hello.o
+    scons: done building targets.
+    </screen>
+    As you see, the internationalized messages ditn't change, so the

+    <para>
+    Let's start with a very simple project, the "Hello world" program 
+    for example
+    <programlisting>
+    /* hello.c */
+    #include &lt;stdio.h&gt;

+    hello = Program(["hello.c"])

+    <command>msgmerge(1)</command> program is used by SCons to update
+    <literal>PO</literal> file. The output from compilation is like:
+    <screen>
+    user@host:$scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.
+    scons: Building targets ...
+    Entering '/home/ptomulik/projects/tmp'
+    xgettext --package-name=hello --package-version=1.0 -o - hello.c
+    Leaving '/home/ptomulik/projects/tmp'
+    Writting 'messages.pot' (messages in file were outdated)
+    msgmerge --update de.po messages.pot
+    ... done.
+    msgfmt -c -o de.mo de.po
+    msgmerge --update en.po messages.pot
+    ... done.
+    msgfmt -c -o en.mo en.po
+    gcc -o hello.o -c hello.c
+    gcc -o hello hello.o
+    Install file: "de.mo" as "locale/de/LC_MESSAGES/hello.mo"
+    Install file: "en.mo" as "locale/en/LC_MESSAGES/hello.mo"
+    msgmerge --update pl.po messages.pot
+    ... done.
+    msgfmt -c -o pl.mo pl.po
+    Install file: "pl.mo" as "locale/pl/LC_MESSAGES/hello.mo"
+    scons: done building targets.
+    </screen>
+    </para>
+    <para>
+    The next example demonstrates what happens if we change the source code
+    in such way that the internationalized messages do not change. The answer
+    is that none of translation files (<literal>POT</literal>,
+    <literal>PO</literal>) are touched (i.e. no content changes, no
+    creation/modification time changed and so on). Let's append another
+    line to the program (after the last printf), so its code becomes:
+    <programlisting>
+    /* hello.c */
+    #include &lt;stdio.h&gt;
+    #include &lt;libintl.h&gt;
+    #include &lt;locale.h&gt;
+    int main(int argc, char* argv[])
+    {
+      bindtextdomain("hello", "locale");
+      setlocale(LC_ALL, "");
+      textdomain("hello");
+      printf(gettext("Hello world\n"));
+      printf(gettext("and good bye\n"));
+      printf("----------------\n");
+      return a;
+    }
+    </programlisting>
+    Compile the project. You'll see on your screen
+    <screen>
+    user@host:$scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.
+    scons: Building targets ...
+    Entering '/home/ptomulik/projects/tmp'
+    xgettext --package-name=hello --package-version=1.0 -o - hello.c
+    Leaving '/home/ptomulik/projects/tmp'
+    Not writting 'messages.pot' (messages in file found to be up-to-date)
+    gcc -o hello.o -c hello.c
+    gcc -o hello hello.o
+    scons: done building targets.
+    </screen>
+    As you see, the internationalized messages ditn't change, so the
+    <literal>POT</literal> and the rest of translation files have not
+    even been touched.
+    </para>
