german translation

Please find attached a german translation file. Suggestion: Move the variables from "You may include the following variables: %site_name, %uid, %node_url, %node_type, %title, %teaser, %body." out of the actual language-dependent text into a variable ("You may include the following variables: %variables") and substitute it with a non-translatable text ("%site_name, %uid, %node_url, %node_type, %title, %teaser, %body"). This way, you won't have to update all translations when adding new variables.
