You need to run the desolat command (with -paths and -paths). Then you need to generate the .po from the po file (use the poedit tool or, not suggested, manually) to your Locale. For example, if you want an Italian translation, you should put cake.po in
/app/Locale/ita/LC_MESSAGES/cake.po
Remember also that for non-basic strings (e.g. month names) you must generate the default.po file in the same folder.
