The online generation system is working at rsync.php.net.
This system generates manuals for all languages with a language-defs.ent file in the translation directory. However the listing of languages at » http://www.php.net/docs and » http://www.php.net/get/docs are static, so only manually added languages show up in those listings.
The build process updates the online manual, and all downloadable ones, excluding the CHM versions. The CHM versions are built on a separate Windows machine, as the compiler is only available for Microsoft Windows.
