Description: Introduction
        ============
        
        This package compiles po files.  It contains a `zest.releaser`_ entry
        point and a stand-alone command line tool.
        
        
        Goal
        ====
        
        You want to release a package that has a ``locales`` dir (or
        ``locale``, or something else as long as it has a ``LC_MESSAGES``
        folder somewhere in it) with translations in ``.po`` files.  You want
        to include the compiled ``.mo`` files in your release as well, but you
        do not want to keep those in a revision control system (like
        subversion) as they are binary and can be easily recreated.  That is
        good.  This package helps with that.
        
        
        Want ``.mo`` files?  Add a ``MANIFEST.in`` file.
        ================================================
        
        When you use ``python setup.py sdist`` to create a source
        distribution, distutils (or setuptools or distribute or distutils2)
        knows which files it should include by looking at the information of
        the revision control system (RCS).  This is why in the case of
        subversion you should use a checkout and not an export: you need the
        versioning information.  (For other RCS or for subversion 1.7+ you
        currently need to install extra packages like setuptools-git.)
        
        Since the compiled ``.mo`` files are best not stored in subversion (or
        any other RCS), you need to give a hint on which files to include.  You
        do this by adding a ``MANIFEST.in`` file.  Let's say your package has
        roughly these contents (not all files are shown)::
        
          your.package/setup.py
          your.package/your/package/locales/nl/LC_MESSAGES/domain.po
        
        Then you need a MANIFEST.in like this::
        
          recursive-include your *
          global-exclude *pyc
        
        This tells distutils to recursively include all (``*``) files and
        directories within the ``your`` directory.  Try it: create a directory
        structure like the above example with a proper ``setup.py``, copy the
        ``domain.po`` file to ``domain.mo`` as a silly test, run ``python
        setup.py sdist`` and check that the ``.mo`` file ends up in the
        created distribution.
        
        Note that the line ``global-exclude *pyc`` may not be strictly
        necessary (at least when using ``zest.releaser`` as it does a fresh
        checkout of a tag when releasing), but it avoids unnecessarily adding
        compiled python files in the release and it does not hurt, except that
        you may get a warning during release::
        
          warning: no previously-included files matching '*pyc' found anywhere in distribution
        
        With that part working, the only thing this ``zest.pocompile`` package
        needs to do, is to actually find all ``.po`` files and compile them to
        ``.mo`` files.  It looks for directories that are named
        ``LC_MESSAGES`` and compiles all ``.po`` files in there.
        
        
        Command line tool
        =================
        
        When you ``easy_install zest.pocompile`` you get a command line tool
        ``pocompile``.  When you run it, this walks the current directory,
        finds all po translation files in a properly formed locales directory
        and compiles them into mo files.  You can also give it a list of
        directories as arguments instead.  Run it with the ``--help`` option
        to get some help.
        
        In the above example, if you are in the ``your.package`` directory and
        run ``pocompile`` it will create this file::
        
          your.package/your/package/locales/nl/LC_MESSAGES/domain.mo
        
        
        zest.releaser entry point
        =========================
        
        You do not need `zest.releaser`_ for proper functioning of
        ``zest.pocompile``.  But if you use the two together, in combination
        with a proper ``MANIFEST.in`` file, releasing a source distribution
        with compiled ``.mo`` files is made easy.
        
        The ``release`` (or ``fullrelease``) command of ``zest.releaser``
        creates a (subversion or other) tag, checks out this tag, creates a
        source distribution (``sdist``) and uploads it to PyPI.  When
        ``zest.pocompile`` is added to the mix, it compiles the ``.po`` files
        immediately after checking out the tag, right in time for creating the
        ``sdist``, which should now contain the ``.mo`` files.
        
        
        Credits
        =======
        
        This package has been cobbled together by Maurits van Rees.
         
        It depends on the `python-gettext`_ package, which itself suggests
        using the Babel_ package, but it does exactly what we need and its
        releases are stored on PyPI, so we ignore that suggestion.
        
        The main functions are taken from the ``build_mo`` command of
        `collective.releaser`_.
        
        Thanks!

        Changelog
        =========
        
        1.1 (2011-12-15)
        ----------------
        
        - Look for ``.po`` files in any ``LC_MESSAGES`` directory.  It no
          longer matters if this is contained in a language directory within a
          ``locales`` or ``locale`` directory, as they could also have names
          like ``plonelocales`` or ``locales_for_version_2_only``.  Note that
          in Plone ``.po`` files can also be in an i18n directory, but those
          should not be compiled; this does not have a ``LC_MESSAGES``
          directory, so we automatically skip it.
