Comment 6 for bug 1282193

translation of cinnamon, cinnamon-control-center and cinnamon-screensaver are in cinnamon-l10n package
from version 3.6 there is also cinnamon-settings-daemon (added today)

translation can be done here:
https://translations.launchpad.net/linuxmint/latest/+lang/it
and will be included in next cinnamon-l10n version

nemo had some files missed from pot generation added recently
if there are still some part not included in latest pot files (check translation link in launchpad) report them
