How to use localized descriptions ?

["Olivier Vitrat" <olivier.vitrat@gmail.com>]

Hello,

How can I use the localized translation files found on ddtp.debian.net
with the new APT (0.6.46) ? It's supposed to be supported, but how to
configure apt to tell him to get the translation-fr file and use it ?
any documentation anywhere about that new feature ?

thanks !!
