As you know, internationalization (phew!) is needed for our software stack. Pau Espin Pedrol had the kindness to translate shr-settings and libframeworkd-phonegui-efl (the library handling the UI of the telephony stack) to spanish and catalan. We took advantage of his translation to reenable the locales generation in unstable. Thus, now, these two translations are available in unstable.
If you are interested in translating these libraries yourself in any language, please refer to http://trac.shr-project.org/trac/wiki/Translating
Meanwhile, thanks a lot Pau :-)
