Some notes about building langpacks.

Create a working directory and choose base repository you are going to use. E. g.: [http://hg.mozilla.org/releases/mozilla-beta beta]

* Clone base directory:
<code>hg clone http://hg.mozilla.org/releases/mozilla-beta</code>

* Create l10n directory. Example with an.
<code>hg clone http://hg.mozilla.org/users/toniher_softcatala.org/an l10n/an</code>

Inside mozilla-beta directory, create a .mozconfig file with the following content:

<pre>
ac_add_options --disable-compile-environment

mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/aragon

ac_add_options --with-l10n-base=/home/toniher/remote-work/mozilla-hg/mozilla-beta/l10n

ac_add_options --enable-application=browser

ac_add_options --enable-official-branding
</pre>

Langpack will be created in a subdirectory inside aragon dir. l10n-base should be changed to fit the path in your system. If creating a langpack for other applications, you should change browser for mail or other.

* Inside mozilla-beta, launch this command: <code>make -f client.mk configure</code>.

* This will generate a <code>Makefile</code> in: aragon/browser/locales

* Go to  aragon/browser/locales, and execute: <code>make langpack-an</code>

* A langpack will be generated in: aragon/dist/linux-x86_64/xpi (depending on your system)

* XPI is a ZIP file. You can change some things inside:
** In install.rdf, increase major version, let's say, from 12.0 to 12.*
** In chrome.manifest file, remove manifest chrome/an.manifest line (not necessary)
** Save them back and you're done.

== Convert PO files to l10n dir ==

If you are using Pootle, you're likely to start with a bunch of PO files and not typical DTD and properties files.

* [http://translate.sourceforge.net/wiki/toolkit/index Install Translate Toolkit]
* [https://translate.svn.sourceforge.net/svnroot/translate/src/trunk/tools/mozilla/get_moz_enUS.py Install get_moz_enUS.py somewhere in your system path]

* Create en-US l10n dir: <code>get_moz_enUS.py -s mozilla-beta -d l10n -p browser</code> (this will create only browser files)
* Create PO templates from l10n/en-US: <code>moz2po -P -t l10n/en-US -i l10n/en-US -o po/pot</code>
* Copy POT files: <code>cp -rf po/pot po/pot.pre</code>
* Rename POT files to PO: <code>find po/pot -name "*.pot" -exec rename "s/\.pot/\.po/" {} \;</code>
* Your locale PO files (e.g. an) are saved in an.pre directory (under an, there are dirs such as browser, toolkit, etc. with PO files inside)
* Merge any missing PO file (even not translated, better than nothing, it would crash otherwise): <code>pomerge -i po/an.pre -t po/pot.pre -o po/an</code> Generates po/an directory.
* Adds any missing one: <code>rsync -r --ignore-existing  po/pot/* po/an</code>
* Generate l10n/an: <code>po2moz -t l10n/en-US -i po/an -o l10n/an</code>
