+  <title>Simple project</title>
+    <para>
+    Let's start with some simple project, the "Hello world" program 
+    for example
+    <scons_example name="ex1">
+    <file name="hello.c" printme="1">
+    /* hello.c */
+    #include &lt;stdio.h&gt;
+    int main(int argc, char* argv[])
+    {
+      printf("Hello world\n");
+      return 0;
+    }
+    </file>
+    </scons_example>
+
+    Prepare simple <filename>SConstruct</filename> script to compile the
+    program.
+    <scons_example name="ex2">
+    <file name="SConstruct" printme="1">
+    # SConstruct
+    env = Environment()
+    hello = Program(["hello.c"])
+    </file>
+    </scons_example>
+    </para>
+
+    <para>
+    Now we'll convert the project to multi-lingual one. I assume, that you
+    already have <ulink
+    url="http://www.gnu.org/software/gettext/manual/gettext.html">GNU gettext
+    utilities</ulink> installed. If not, install it from repository, or
+    download from <ulink url="http://ftp.gnu.org/gnu/gettext/">
+    http://ftp.gnu.org/gnu/gettext/</ulink>. For the purpose of this example,
+    you should have following three locales installed on your system 
+    <literal>en_US</literal>, <literal>de_DE</literal> and
+    <literal>pl_PL</literal>. On debian, for example, you may enable certain
+    locales through <command>dpkg-reconfigure locales</command>.
+    </para>
+
+    <para>
+    We 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;
+    #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"));
+      return 0;
+    }
+    </file>
+    </scons_example>
+    This way we prepared source code. Detailed recipes for such preparation 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> in above source has two purposes.
+    First is is recognized by 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, we use &b-link-Translate; builder and &b-link-MOFiles; builder.
+    First one takes a couple of 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. After all, we install the <literal>MO</literal> files under directory
+    called <filename>locale</filename>.
+    </para>
+
+    <para>  The complete code of 
+    <filename>SConstruct</filename> script for multi-lingual "Hello world" will
+    be following:
+    <scons_example name="ex4">
+    <file name="SConstruct" printme="1">
+    # SConstruct
+    env = Environment( tools = ['default', 'gettext'] )
+    hello = env.Program(["hello.c"])
+    env['XGETTEXTFLAGS'] = [
+      '--package-name=%s' % 'hello',
+      '--package-version=%s' % '1.0',
+    ]
+    po = env.Translate(["pl","en", "de"], ["hello.c"], POAUTOINIT = 1)
+    mo = env.MOFiles(po)
+    InstallAs(["locale/en/LC_MESSAGES/hello.mo"], ["en.mo"])
+    InstallAs(["locale/pl/LC_MESSAGES/hello.mo"], ["pl.mo"])
+    InstallAs(["locale/de/LC_MESSAGES/hello.mo"], ["de.mo"])
+    </file>
+    </scons_example>
+    </para>
+    <para>
+    Generate translation files with <command>scons po-update</command>.
+    You should see the output from SCons simillar to this:
+    <screen>
+    ptomulik@:$ scons po-update
+    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' (new file)
+    msginit --no-translator -l pl -i messages.pot -o pl.po
+    Created pl.po.
+    msginit --no-translator -l en -i messages.pot -o en.po
+    Created en.po.
+    msginit --no-translator -l de -i messages.pot -o de.po
+    Created de.po.
+    scons: done building targets.
+    </screen>
+    </para>
+
+    <para>
+    If everything is right, you shall see following new files.
+    <screen>
+    ptomulik@:$ ls *.po*
+    de.po  en.po  messages.pot  pl.po
+    </screen>
+    </para>
+
+    <para>
+    Open <filename>en.po</filename> in <command>poedit</command> and provide
+    english "translation" to message <literal>"Hello world\n"</literal>. Do the
+    same for <filename>de.po</filename> (deutsch) and
+    <filename>pl.po</filename> (polish). Let the translations be, for example:
+    <itemizedlist>
+      <listitem><para>
+        <literal>en: "Welcome to beautiful world!\n"</literal>
+      </para></listitem>
+      <listitem><para>
+        <literal>de: "Hallo Welt!\n"</literal>
+      </para></listitem>
+      <listitem><para>
+        <literal>pl: "Witaj swiecie!\n"</literal>
+      </para></listitem>
+    </itemizedlist>
+    </para>
+    <para>
+    Now compile the project by executing <command>scons</command> command. The
+    output should be similar to this:
+    <screen>
+    ptomulik@:$ scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.
+    scons: Building targets ...
+    msgfmt -c -o de.mo de.po
+    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"
+    msgfmt -c -o pl.mo pl.po
+    Install file: "pl.mo" as "locale/pl/LC_MESSAGES/hello.mo"
+    scons: done building targets.
+    </screen>
+    SCons automatically compiled <literal>PO</literal> files to binary format
+    <literal>MO</literal>, and the <literal>InstallAs</literal> lines installed
+    these files under <filename>locale</filename> folder.
+    </para>
+    <para>
+    Your program should be now ready. You may try it as follows (linux):
+    <screen>
+    ptomulik@:$ LANG=en_US.UTF-8 ./hello
+    Welcome to beautiful world
+    </screen>
+    <screen>
+    ptomulik@:$ LANG=de_DE.UTF-8 ./hello
+    Hallo Welt
+    </screen>
+    <screen>
+    ptomulik@:$ LANG=pl_PL.UTF-8 ./hello
+    Witaj swiecie
+    </screen>
+    </para>
+    <para>
+    To demonstrate further life of translation files, let's change polish
+    translation (<command>poedit pl.po</command>) to <literal>"Witaj drogi
+    swiecie\n"</literal>. Run <command>scons</command> to see how scons
+    reacts to this
+    <screen>
+    ptomulik@:$scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.
+    scons: Building targets ...
+    msgfmt -c -o pl.mo pl.po
+    Install file: "pl.mo" as "locale/pl/LC_MESSAGES/hello.mo"
+    scons: done building targets.
+    </screen>
+    </para>
+    <para>
+    Now, open <filename>hello.c</filename> and add another one
+    <literal>printf</literal> line with new message.
+    <scons_example name="ex5">
+    <file name="hello.c" printme="1">
+    /* hello.c */
+    #include &lt;stdio.h&gt;
+    #include &lt;libintl.h&gt;
+    #include &lt;locale.h&gt;
+    int main(int argc, char* argv[])
+    {
+      bindtextdomain("hello", "locale");
+      setlocale(LC_ALL, "");
+      textdomain("hello");
+      printf(gettext("Hello world\n"));
+      printf(gettext("and good bye\n"));
+      return 0;
+    }
+    </file>
+    </scons_example>
+    </para>
+    <para>
+    Compile project with <command>scons</command>. This time, the
+    <command>msgmerge(1)</command> program is used by SCons to update
+    <literal>PO</literal> file. The output from compilation is like:
+    <screen>
+    ptomulik@:$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 last 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>) is touched (i.e. no content changes, no
+    creation/modification time changed and so on). Let's append another one
+    instruction 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 project. You'll see on your screen
+    <screen>
+    ptomulik@:$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>
+    Now compile the project by executing <command>scons</command> command. The

+    SCons automatically compiled <literal>PO</literal> files to binary format

+    these files under <filename>locale</filename> folder.
+    </para>
+    <para>
+    Your program should be now ready. You may try it as follows (linux):
+    <screen>

+    </para>
+    <para>
+    To demonstrate further life of translation files, let's change polish
+    translation (<command>poedit pl.po</command>) to <literal>"Witaj drogi
+    swiecie\n"</literal>. Run <command>scons</command> to see how scons
+    reacts to this
+    <screen>
+    ptomulik@:$scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.

+    scons: done building targets.
+    </screen>
+    </para>
+    <para>
+    Now, open <filename>hello.c</filename> and add another one
+    <literal>printf</literal> line with new message.
+    <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"));
+      return 0;
+    }
+    </programlisting>
+    </para>
+    <para>
+    Compile project with <command>scons</command>. This time, the
+    <command>msgmerge(1)</command> program is used by SCons to update
+    <literal>PO</literal> file. The output from compilation is like:
+    <screen>
+    ptomulik@:$scons
+    scons: Reading SConscript files ...
+    scons: done reading SConscript files.
+    scons: Building targets ...
+    Entering '/home/ptomulik/projects/tmp'
+    xgettext --package-name=hello --package-version=1.0 -o - hello.c
+    Leaving '/home/ptomulik/projects/tmp'
+    Writting 'messages.pot' (messages in file were outdated)
+    msgmerge --update de.po messages.pot
+    ... done.
+    msgfmt -c -o de.mo de.po
+    msgmerge --update en.po messages.pot
+    ... done.
+    msgfmt -c -o en.mo en.po
+    gcc -o hello.o -c hello.c
+    gcc -o hello hello.o
+    Install file: "de.mo" as "locale/de/LC_MESSAGES/hello.mo"
+    Install file: "en.mo" as "locale/en/LC_MESSAGES/hello.mo"
+    msgmerge --update pl.po messages.pot
+    ... done.
+    msgfmt -c -o pl.mo pl.po
+    Install file: "pl.mo" as "locale/pl/LC_MESSAGES/hello.mo"
+    scons: done building targets.
+    </screen>
+    </para>
+    <para>
+    The last example demonstrates what happens, if we change the source code
+    in such way, that the internationalized messages do not change. The answer
+    is, that none of translation files (<literal>POT</literal>,
+    <literal>PO</literal>) is touched (i.e. no content changes, no
+    creation/modification time changed and so on). Let's append another one
+    instruction to the program (after the last printf), so its code becomes:
+    <programlisting>
+    /* hello.c */
+    #include &lt;stdio.h&gt;
+    #include &lt;libintl.h&gt;
+    #include &lt;locale.h&gt;
+    int main(int argc, char* argv[])
+    {
+      bindtextdomain("hello", "locale");
+      setlocale(LC_ALL, "");
+      textdomain("hello");
+      printf(gettext("Hello world\n"));
+      printf(gettext("and good bye\n"));
+      printf("----------------\n");
+      return a;
+    }
+    </programlisting>
+    Compile project. You'll see on your screen
+    <screen>
+    ptomulik@:$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.

+
+  It seems like `SCons.Node.FS.Base.get_path()` returns absolute paths
+  for nodes that are outside of current working directory (`env.fs.getcwd()`).
+  In `SConsToolGettext` way we often have `SConscript`, `POT` and `PO` files
+  within `po/` directory and source files (e.g. `*.c`) outside of it. When
+  generating `POT` template file, references to source files are written to
+  `POT` template, so a translator may later quickly jump to appropriate source
+  file and line from its `PO` editor (e.g. `poedit`).  Relative paths in  
+  `PO` file are usually interpreted by `PO` editor as paths relative to the
+  place, where `PO` file lives. The absolute paths would make resultant `POT`
+  file nonportable, as the references would be correct only on the machine,
+  where `POT` file was recently re-created. For such reason, we need a
+  function, which always returns relative paths. This is the purpose of
+  `RPaths` callable object.
+
+  The `__call__` method returns paths relative to current woking directory, but
+  we assume, that *xgettext(1)* is run from the directory, where target file is
+  going to be created.

+  across different drives on windows. We assume here, that single local
+  filesystem holds both source files and target `POT` templates.

+<tool name="gettext">
+<summary>
+This is actually a toolset, which supports internationalization and
+localization of sofware being constructed with SCons. The toolset loads
+following tools:
+
+<itemizedlist mark='opencircle'>
+  <listitem><para>
+    &t-link-xgettext; - to extract internationalized messages from source code to 
+    <literal>POT</literal> file(s),
+  </para></listitem>
+  <listitem><para>
+    &t-link-msginit; - may be optionally used to initialize <literal>PO</literal>
+    files,
+  </para></listitem>
+  <listitem><para>
+    &t-link-msgmerge; - to update <literal>PO</literal> files, that already contain
+    translated messages,</para></listitem>
+  <listitem><para>
+    &t-link-msgfmt; - to compile textual <literal>PO</literal> file to binary
+    installable <literal>MO</literal> file.
+  </para></listitem>
+</itemizedlist>
+
+When you enable &t-gettext;, it internally loads all abovementioned tools,
+so you're encouraged to see their individual documentation.
+
+Each of the above tools provides its own builder(s) which may be used to
+perform particular activities related to software internationalization. You
+may be however interested in <emphasis>top-level</emphasis> builders
+&b-Translate; and &b-InstallMOFiles; described few paragraphs later.
+
+To use &t-gettext; tools, copy <filename>SConsToolGettext</filename>
+folder to your <filename>site_scons/</filename> and simply add
+<literal>'gettext'</literal> tool to your environment:
+<example>
+  env = Environment( tools = ['default', 'gettext'] )
+</example>
+</summary>
+<sets>
+</sets>
+<uses>
+<!-- PLATFORM -->
+</uses>
+</tool>
+
+<builder name="Translate">
+<summary>
+This pseudo-builder belongs to &t-link-gettext; toolset. The builder extracts
+internationalized messages from source files, updates <literal>POT</literal>
+template (if necessary) and then updates <literal>PO</literal> translations (if
+necessary). If &cv-link-POAUTOINIT; is set, missing <literal>PO</literal> files
+will be automatically created (i.e. without translator person intervention).
+The variables &cv-link-LINGUAS_FILE; and &cv-link-POTDOMAIN; are taken into
+acount too. All other construction variables used by &b-link-POTUpdate;, and
+&b-link-POUpdate; work here too.
+
+<emphasis>Example 1</emphasis>.
+The simplest way is to specify input files and output languages inline in
+a SCons script when invoking &b-Translate;
+<example>
+# SConscript in 'po/' directory
+env = Environment( tools = ["default", "gettext"] )
+env['POAUTOINIT'] = 1
+env.Translate(['en','pl'], ['../a.cpp','../b.cpp']) 
+</example>
+
+<emphasis>Example 2</emphasis>.
+If you wish, you may also stick to conventional style known from
+<productname>autotools</productname>, i.e. using
+<filename>POTFILES.in</filename> and <filename>LINGUAS</filename> files
+<example>
+# LINGUAS
+en pl 
+#end
+</example>
+
+<example>
+# POTFILES.in
+a.cpp
+b.cpp
+# end
+</example>
+
+<example>
+# SConscript
+env = Environment( tools = ["default", "gettext"] )
+env['POAUTOINIT'] = 1
+env['XGETTEXTPATH'] = ['../']
+env.Translate(LINGUAS_FILE = 1, XGETTEXTFROM = 'POTFILES.in') 
+</example>
+
+The last approach is perhaps the recommended one. It allows easily split
+internationalization/localization onto separate SCons scripts, where a script
+in source tree is responsible for translations (from sources to
+<literal>PO</literal> files) and script(s) under variant directories are
+responsible for compilation of <literal>PO</literal> to <literal>MO</literal>
+files to and for installation of <literal>MO</literal> files. The "gluing
+factor" synchronizing these two scripts is then the content of
+<filename>LINGUAS</filename> file.  Note, that the updated
+<literal>POT</literal> and <literal>PO</literal> files are usually going to be
+committed back to the repository, so they must be updated within the source
+directory (and not in variant directories). Additionaly, the file listing of
+<filename>po/</filename> directory contains <filename>LINGUAS</filename> file,
+so the source tree looks familiar to translators, and they may work with the
+project in their usual way.
+
+<emphasis>Example 3</emphasis>.
+Let's prepare a development tree as below
+<example>
+ project/
+  + SConstruct
+  + build/        
+  + src/
+      + po/
+          + SConscript
+          + SConscript.i18n
+          + POTFILES.in
+          + LINGUAS
+</example>
+with <filename>build</filename> being variant directory. Write the top-level
+<filename>SConstruct</filename> script as follows
+<example>
+  # SConstruct
+  env = Environment( tools = ["default", "gettext"] )
+  VariantDir('build', 'src', duplicate = 0)
+  env['POAUTOINIT'] = 1
+  SConscript('src/po/SConscript.i18n', exports = 'env')
+  SConscript('build/po/SConscript', exports = 'env')
+</example>
+the <filename>src/po/SConscript.i18n</filename> as
+<example>
+  # src/po/SConscript.i18n
+  Import('env')
+  env.Translate(LINGUAS_FILE=1, XGETTEXTFROM='POTFILES.in', XGETTEXTPATH=['../'])
+</example>
+and the <filename>src/po/SConscript</filename>
+<example>
+  # src/po/SConscript
+  Import('env')
+  env.MOFiles(LINGUAS_FILE = 1)
+</example>
+Such setup produces <literal>POT</literal> and <literal>PO</literal> files
+under source tree in <filename>src/po/</filename> and binary
+<literal>MO</literal> files under variant tree in
+<filename>build/po/</filename>. This way the <literal>POT</literal> and
+<literal>PO</literal> files are separated from other output files, which must
+not be committed back to source repositories (e.g. <literal>MO</literal>
+files).
+
+<note><para>In above example, the <literal>PO</literal> files are not updated,
+nor created automatically when you issue <command>scons '.'</command> command.
+The files must be updated (created) by hand via <command>scons
+po-update</command> and then <literal>MO</literal> files can be compiled by
+running <command>scons '.'</command>.</para></note>
+

+- <literal>domain</literal> - domain, i.e. your package/program name
+- <literal>category</literal> - locale category, e.g. <literal>LC_MESSAGES</literal>

+The installation goes in standard way. For example, if

+This scons tool is a part of scons &t-link-gettext; toolset. It provides

+<builder name="POInit">
+<summary>
+This builder belongs to &t-link-msginit; tool. The builder initializes missing
+<literal>PO</literal> file(s) if &cv-link-POAUTOINIT; is set.  If
+&cv-link-POAUTOINIT; is not set (default), &b-POInit; prints instruction for
+user (that is supposed to be a translator), telling how the
+<literal>PO</literal> file should be initialized. In normal projects
+<emphasis>you should not use &b-POInit; and use &b-link-POUpdate;
+instead</emphasis>. &b-link-POUpdate; chooses intelligently between
+<command>msgmerge(1)</command> and <command>msginit(1)</command>. &b-POInit;
+always uses <command>msginit(1)</command> and should be regarded as builder for
+special purposes or for temporary use (e.g. for quick, one time initialization
+of a bunch of <literal>PO</literal> files) or for tests.
+
+Target nodes defined through &b-POInit; are not built by default (they're
+<literal>Ignore</literal>d from <literal>'.'</literal> node) but are added to
+special <literal>Alias</literal> (<literal>'po-create'</literal> by default).
+The alias name may be changed through the &cv-link-POCREATE_ALIAS;
+construction variable. All <literal>PO</literal> files defined through
+&b-POInit; may be easily initialized by <command>scons po-create</command>.
+
+<emphasis>Example 1</emphasis>.
+Initialize <filename>en.po</filename> and <filename>pl.po</filename> from
+<filename>messages.pot</filename>:
+<example>
+  # ...
+  env.POInit(['en', 'pl']) # messages.pot --&gt; [en.po, pl.po] 
+</example>
+
+<emphasis>Example 2</emphasis>.
+Initialize <filename>en.po</filename> and <filename>pl.po</filename> from
+<filename>foo.pot</filename>:
+<example>
+  # ...
+  env.POInit(['en', 'pl'], ['foo']) # foo.pot --&gt; [en.po, pl.po] 
+</example>
+
+<emphasis>Example 3</emphasis>.
+Initialize <filename>en.po</filename> and <filename>pl.po</filename> from
+<filename>foo.pot</filename> but using &cv-link-POTDOMAIN; construction
+variable:
+<example>
+  # ...
+  env.POInit(['en', 'pl'], POTDOMAIN='foo') # foo.pot --&gt; [en.po, pl.po] 
+</example>
+
+<emphasis>Example 4</emphasis>.
+Initialize <literal>PO</literal> files for languages defined in
+<filename>LINGUAS</filename> file. The files will be initialized from template
+<filename>messages.pot</filename>:
+<example>
+  # ...
+  env.POInit(LINGUAS_FILE = 1) # needs 'LINGUAS' file
+</example>
+
+<emphasis>Example 5</emphasis>.
+Initialize <filename>en.po</filename> and <filename>pl.pl</filename>
+<literal>PO</literal> files plus files for languages defined in
+<filename>LINGUAS</filename> file. The files will be initialized from template
+<filename>messages.pot</filename>:
+<example>
+  # ...
+  env.POInit(['en', 'pl'], LINGUAS_FILE = 1)
+</example>
+
+<emphasis>Example 6</emphasis>.
+You may preconfigure your environment first, and then initialize
+<literal>PO</literal> files:
+<example>
+  # ...
+  env['POAUTOINIT'] = 1
+  env['LINGUAS_FILE'] = 1
+  env['POTDOMAIN'] = 'foo'
+  env.POInit()
+</example>
+which has same efect as:

+This scons tool is a part of scons &t-link-gettext; toolset. It provides

+<builder name="POTUpdate">
+<summary>
+The builder belongs to &t-link-xgettext; tool. The builder updates target
+<literal>POT</literal> file if exists or creates one if it doesn't. The node is
+not built by default (i.e. it is <literal>Ignore</literal>d from
+<literal>'.'</literal>), but only on demand (i.e.  when given
+<literal>POT</literal> file is required or when special alias is invoked). This
+builder adds its targe node (<filename>messages.pot</filename>, say) to a
+special alias (<literal>pot-update</literal> by default, see
+&cv-link-POTUPDATE_ALIAS;) so you can update/create them easily with
+<command>scons pot-update</command>. The file is not written until there is no
+real change in internationalized messages (or in comments that enter
+<literal>POT</literal> file). 
+
+<note> <para>You may see <command>xgettext(1)</command> being invoked by the
+&t-link-xgettext; tool even if there is no real change in internationalized
+messages (so the <literal>POT</literal> file is not being updated).  This
+happens every time  a source file has changed. In such case we invoke
+<command>xgettext(1)</command> and compare its output with the content of
+<literal>POT</literal> file to decide whether the file should be updated or
+not.</para></note>
+
+<emphasis>Example 1.</emphasis>
+Let's create <filename>po/</filename> directory and place following
+<filename>SConstruct</filename> script there:
+<example>
+  # SConstruct in 'po/' subdir
+  env = Environment( tools = ['default', 'xgettext'] )
+  env.POTUpdate(['foo'], ['../a.cpp', '../b.cpp'])
+  env.POTUpdate(['bar'], ['../c.cpp', '../d.cpp'])
+</example>      
+Then invoke scons few times:
+<example>
+  user@host:$ scons             # Does not create foo.pot nor bar.pot
+  user@host:$ scons foo.pot     # Updates or creates foo.pot
+  user@host:$ scons pot-update  # Updates or creates foo.pot and bar.pot
+  user@host:$ scons -c          # Does not clean foo.pot nor bar.pot.
+</example>
+the results shall be as the comments above say.
+
+<emphasis>Example 2.</emphasis>
+The &b-POTUpdate; builder may be used with no target specified, in which
+case default target <filename>messages.pot</filename> will be used. The
+default target may also be overriden by setting &cv-link-POTDOMAIN; construction
+variable or providing it as an override to &b-POTUpdate; builder:
+<example>    
+  # SConstruct script
+  env = Environment( tools = ['default', 'xgettext'] )
+  env['POTDOMAIN'] = "foo"
+  env.POTUpdate(source = ["a.cpp", "b.cpp"]) # Creates foo.pot ...
+  env.POTUpdate(POTDOMAIN = "bar", source = ["c.cpp", "d.cpp"]) # and bar.pot
+</example>
+
+<emphasis>Example 3.</emphasis>
+The sources may be specified within separate file, for example
+<filename>POTFILES.in</filename>:
+<example>      
+  # POTFILES.in in 'po/' subdirectory
+  ../a.cpp
+  ../b.cpp
+  # end of file
+</example>    
+The name of the file (<filename>POTFILES.in</filename>) containing the list of
+sources is provided via &cv-link-XGETTEXTFROM;:
+<example>      
+  # SConstruct file in 'po/' subdirectory
+  env = Environment( tools = ['default', 'xgettext'] )
+  env.POTUpdate(XGETTEXTFROM = 'POTFILES.in')
+</example>    
+
+<emphasis>Example 4.</emphasis>
+You may use &cv-link-XGETTEXTPATH; to define source search path. Assume, for
+example, that you have files <filename>a.cpp</filename>,
+<filename>b.cpp</filename>, <filename>po/SConstruct</filename>,
+<filename>po/POTFILES.in</filename>. Then your <literal>POT</literal>-related
+files could look as below:
+<example>
+  # POTFILES.in in 'po/' subdirectory
+  a.cpp
+  b.cpp
+  # end of file
+</example>
+
+<example>
+  # SConstruct file in 'po/' subdirectory
+  env = Environment( tools = ['default', 'xgettext'] )
+  env.POTUpdate(XGETTEXTFROM = 'POTFILES.in', XGETTEXTPATH='../')
+</example>
+
+<emphasis>Example 5.</emphasis>
+Multiple search directories may be defined within a list, i.e.
+<literal>XGETTEXTPATH = ['dir1', 'dir2', ...]</literal>. The order in the list
+determines the search order of source files. The path to the first file found
+is used.
+
+Let's create <filename>0/1/po/SConstruct</filename> script:
+<example>
+  # SConstruct file in '0/1/po/' subdirectory
+  env = Environment( tools = ['default', 'xgettext'] )
+  env.POTUpdate(XGETTEXTFROM = 'POTFILES.in', XGETTEXTPATH=['../', '../../'])
+</example>
+and <filename>0/1/po/POTFILES.in</filename>:
+<example>
+  # POTFILES.in in '0/1/po/' subdirectory
+  a.cpp
+  # end of file
+</example>
+Write two <filename>*.cpp</filename> files, the first one is
+<filename>0/a.cpp</filename>:
+<example>
+  /* 0/a.cpp */
+  gettext("Hello from ../../a.cpp")
+</example>
+and the second is <filename>0/1/a.cpp</filename>:
+<example>
+  /* 0/1/a.cpp */
+  gettext("Hello from ../a.cpp")
+</example>
+then run scons. You'll obtain <literal>0/1/po/messages.pot</literal> with the
+message <literal>"Hello from ../a.cpp"</literal>. When you reverse order in
+<varname>$XGETTEXTFOM</varname>, i.e. when you write SConscript as
+<example>
+  # SConstruct file in '0/1/po/' subdirectory
+  env = Environment( tools = ['default', 'xgettext'] )
+  env.POTUpdate(XGETTEXTFROM = 'POTFILES.in', XGETTEXTPATH=['../../', '../'])
+</example> then the <filename>messages.pot</filename> will contain
+<literal>msgid "Hello from ../../a.cpp"</literal> line and not 
+<literal>msgid "Hello from ../a.cpp"</literal>.
