[xwiki-users] localization of XWiki into Arabic

Dear all, I installed the workspace version, which need Jetty and HSQL D Directories don't includes any file containg the localized strings, or may be the are somewhere else, in package? I would like to start the localization of XWiki into Arabic. To do so, I need your help to know the nature of strings to translate. Thanks in advance. -- Youcef
